Trądzik
Objawy

Trądzik pospolity (acne vulgaris) jest przewlekłą chorobą skóry wynikającą z zatkania mieszków włosowych przez nadmiar sebum i keratynę, z udziałem bakterii Cutibacterium acnes, co prowadzi do różnorodnych zmian skórnych: zaskórników zamkniętych i otwartych, grudek, krost, guzków oraz torbieli. Lokalizacja zmian obejmuje głównie twarz, plecy, klatkę piersiową i ramiona. Nasilenie trądziku klasyfikuje się jako łagodne (<20 zaskórników i/lub <15 zmian zapalnych), umiarkowane (20-100 zaskórników, 15-50 zmian zapalnych, do 5 guzków) oraz ciężkie (>100 zaskórników, >50 zmian zapalnych, >5 guzków lub torbieli). Patogeneza obejmuje nadprodukcję sebum pod wpływem androgenów, zatkanie ujść mieszków, proliferację bakterii i rozwój stanu zapalnego, co może prowadzić do bliznowacenia i przebarwień pozapalnych.

Objawy trądziku

Trądzik (acne vulgaris) to częsta choroba skóry, która występuje, gdy mieszki włosowe zostają zatkane przez nadmiar sebum i martwe komórki naskórka. Jest to schorzenie dotykające głównie nastolatków, choć może wystąpić w każdym wieku. Objawy trądziku mogą różnić się w zależności od nasilenia choroby i obejmują charakterystyczne zmiany skórne występujące najczęściej na twarzy, plecach, klatce piersiowej oraz ramionach12.

Rodzaje zmian trądzikowych

W trądziku można wyróżnić kilka podstawowych typów zmian skórnych, które różnią się wyglądem i stopniem nasilenia stanu zapalnego1:

  • Zaskórniki zamknięte (whiteheads) – małe, białe lub cieliste guzki pod powierzchnią skóry, powstające gdy nadmiar sebum i martwe komórki naskórka zatykają pory12
  • Zaskórniki otwarte (blackheads) – drobne czarne lub żółtawe guzki, które powstają gdy zablokowane pory pozostają otwarte, a ich zabarwienie nie jest wynikiem zabrudzenia, lecz oksydacji sebum i odkładania się melaniny12
  • Grudki (papules) – małe, zaczerwienione, wypukłe i często bolesne lub tkliwe guzki, będące wynikiem stanu zapalnego11
  • Krosty (pustules) – podobne do grudek, ale z białą lub żółtą czapeczką wypełnioną ropą w środku, powstają, gdy bakterie namnażają się w nadmiarze sebum22
  • Guzki (nodules) – duże, twarde, bolesne guzy pod skórą, które mogą powodować ból i prowadzić do bliznowacenia12
  • Torbiele (cysts) – głębokie, bolesne, wypełnione ropą zmiany pod skórą, stanowiące najcięższą formę trądziku, niosące największe ryzyko powstania blizn11

Lokalizacja zmian trądzikowych

Trądzik najczęściej występuje w miejscach o dużej koncentracji gruczołów łojowych. Typowe lokalizacje obejmują11:

  • Twarz – występuje u prawie wszystkich osób z trądzikiem
  • Plecy – dotyka ponad połowę osób z trądzikiem
  • Klatka piersiowa – występuje u około 15% osób z trądzikiem
  • Szyja, barki i ramiona – również są często dotknięte zmianami

Nasilenie trądziku

Stopień nasilenia trądziku jest istotnym elementem oceny klinicznej i ma wpływ na wybór odpowiedniego leczenia. Nasilenie trądziku zazwyczaj kategoryzuje się jako łagodne, umiarkowane lub ciężkie11.

Trądzik łagodny

Charakteryzuje się przede wszystkim obecnością zaskórników (otwartych i zamkniętych) z niewielką liczbą grudek i krost zapalnych. Objawy są zazwyczaj ograniczone do twarzy, a zmiany nie są liczne11. W przypadku trądziku łagodnego występuje mniej niż 20 zaskórników i/lub mniej niż 15 zapalnych grudek i krost1.

Trądzik umiarkowany

W trądziku umiarkowanym występuje więcej rozsianych zaskórników, grudek i krost zapalnych. Zmiany mogą pojawiać się nie tylko na twarzy, ale również na plecach i klatce piersiowej1. W tej postaci obserwuje się od 20 do 100 zaskórników i/lub od 15 do 50 zmian zapalnych (grudek i krost), może występować do 5 guzków1.

Trądzik ciężki

Trądzik ciężki charakteryzuje się licznymi dużymi, bolesnymi grudkami, krostami, guzkami lub torbielami. W tej postaci często występuje ryzyko bliznowacenia1. W ciężkim trądziku występuje ponad 100 zaskórników, ponad 50 zmian zapalnych i ponad 5 guzków lub torbieli1. Zmiany mogą obejmować nie tylko twarz, ale również szyję, plecy, klatkę piersiową i ramiona3.

Mechanizm powstawania trądziku

Rozwój trądziku jest złożonym procesem, który obejmuje kilka powiązanych ze sobą mechanizmów patofizjologicznych1.

mikrozaskórnika”>Powstawanie mikrozaskórnika

Podstawową zmianą w trądziku jest mikrozaskórnik (microcomedo), który stanowi prekursora wszystkich klinicznych objawów trądziku1. Rozwój trądziku rozpoczyna się, gdy mieszki włosowe zostają zatkane przez nadmiar sebum (łoju) i martwe komórki naskórka2. Proces ten jest stymulowany przez hormony, szczególnie androgeny, które zwiększają produkcję sebum przez gruczoły łojowe2.

W miarę gromadzenia się materiału keratynowego i sebum mikrozaskórnik przekształca się w zaskórnik zamknięty. Poprzez stopniowe rozszerzanie się ujścia mieszka włosowego powstaje zaskórnik otwarty1.

Rola bakterii i stanu zapalnego

W rozwoju trądziku istotną rolę odgrywają bakterie Cutibacterium acnes (dawniej Propionibacterium acnes), które normalnie bytują na skórze1. Gdy mieszki włosowe zostają zablokowane, bakterie te namnażają się w nadmiarze sebum, rozkładając je na substancje drażniące skórę, co prowadzi do stanu zapalnego1.

W miarę nasilania się stanu zapalnego mieszki włosowe mogą pęknąć, uwalniając bakterie, keratynę i prozapalne lipidy do otaczającej skóry właściwej, co nasila stan zapalny i prowadzi do tworzenia się guzków i torbieli1. Zapalenie powierzchowne prowadzi do powstania krost, natomiast głębsze zapalenie powoduje tworzenie się grudek, a jeszcze głębsze – torbieli1.

Progresja trądziku

Trądzik, w przeciwieństwie do pojedynczych pryszczy, rozwija się przez dłuższy czas i utrzymuje się przez dłuższy okres1. Przebieg trądziku można podzielić na kilka etapów, które odzwierciedlają postępującą naturę tej choroby1.

Etapy rozwoju trądziku

  1. Etap niezapalny (komedony) – początkowa faza rozwoju trądziku, charakteryzująca się powstawaniem zaskórników otwartych i zamkniętych wskutek nieznacznych zatorów w mieszkach włosowych1
  2. Etap łagodnego zapalenia – pojawia się zaczerwienienie i lekki stan zapalny na powierzchni skóry, tworzą się grudki (papules), które są czerwone i obrzęknięte z powodu zapalenia skóry2
  3. Etap umiarkowanego zapalenia – stan zapalny staje się bardziej widoczny, pojawiają się krosty (pustules) z charakterystyczną czerwoną podstawą zakończoną żółtawą lub białą główką wypełnioną ropą2
  4. Etap guzków – na tym etapie można wyczuć twarde, bolesne guzki pod powierzchnią skóry, będące wynikiem głębszego stanu zapalnego3
  5. Etap torbieli – najcięższy etap trądziku, charakteryzujący się dużymi, zawierającymi ropę torbielami głęboko umiejscowionymi w podskórnych warstwach skóry, powodującymi dyskomfort i stan zapalny3

Cykl życia pryszcza

Pojedynczy pryszcz przechodzi przez swój własny cykl życiowy. Zanim stanie się widoczny, mikroskopijne ilości sebum i złuszczonych komórek mogą zostać uwięzione w porach, tworząc mikrozaskórniki – „zarodki” pryszczy, które są niewykrywalne gołym okiem1.

Gdy zatkany por (zaskórnik) zostaje zainfekowany i zapalony przez bakterie naturalnie występujące na skórze, tworzy się czerwony, bolesny guzek – pryszcz. Większość pryszczy zaczyna się goić i kurczyć w ciągu tygodnia, choć czasem może wydawać się, że trwa to wieczność2.

Podczas gojenia się pryszczy mogą wystąpić problemy skórne, takie jak swędzenie, łuszczenie się lub złuszczanie – wszystko to naturalne objawy naprawy otaczającej skóry2.

Trądzik w różnych grupach wiekowych

Trądzik jest najbardziej powszechny wśród nastolatków, ale może wystąpić w każdym wieku – od dzieciństwa po dorosłość1.

Trądzik u nastolatków

Trądzik dotyka około 80-90% młodych ludzi, przy czym 20-30% z nich będzie szukać pomocy medycznej1. Trądzik młodzieńczy jest ściśle związany ze zmianami hormonalnymi zachodzącymi w okresie dojrzewania, kiedy to zwiększona produkcja androgenów, zwłaszcza testosteronu, stymuluje gruczoły łojowe do produkcji większej ilości sebum1.

U nastolatków trądzik zwykle pojawia się na twarzy, plecach, klatce piersiowej i ramionach2. Większość przypadków trądziku ustępuje samoistnie po okresie dojrzewania, zazwyczaj w połowie lub pod koniec lat 20-tych2.

Trądzik u dorosłych

Trądzik u dorosłych (postadolescent acne) może być przetrwały, z początkiem w okresie nastoletnim, lub o późnym początku, rozpoczynającym się po 25. roku życia1. Dotyka on do 15% kobiet i jest u nich znacznie częstszy niż u mężczyzn1.

U około 5% mężczyzn trądzik utrzymuje się w wieku 25 lat, podczas gdy u kobiet odsetek ten wynosi 12%. W wieku 45 lat trądzik ma nadal 5% kobiet2. Trądzik u dorosłych kobiet często pojawia się wzdłuż linii żuchwy, co może sugerować zaburzenie hormonalne1.

U dorosłych trądzik może mieć następujące cechy charakterystyczne1:

  • Jest zazwyczaj łagodny do umiarkowanego pod względem nasilenia
  • Dotknięte kobiety często skarżą się na powiększone pory
  • Zmiany zapalne są częste na linii żuchwy i szyi
  • Zaostrzenia przedmiesiączkowe są powszechne
  • Makrozaskórniki (duże zaskórniki zamknięte) są częstsze niż u młodszych osób

Powikłania trądziku

Trądzik, zwłaszcza nieleczony lub w ciężkiej postaci, może prowadzić do różnych powikłań, zarówno fizycznych, jak i psychologicznych2.

Bliznowacenie

Bliznowacenie jest jednym z najpoważniejszych powikłań trądziku i szacuje się, że dotyka 95% osób z trądzikiem pospolitym1. Blizny są spowodowane stanem zapalnym w skórze właściwej i nieprawidłowym procesem gojenia1.

Blizny potrądzikowe mogą przybierać różne formy2:

  • Małe, płaskie blizny, które są ledwo zauważalne
  • Wyraźnie widoczne blizny wgłobione (tzw. „ice-pick scars” – przypominające nakłucia lodu)
  • Większe doły, płytkie zagłębienia w skórze
  • Czerwone, wypukłe blizny

Bliznowacenie jest najbardziej prawdopodobne w przypadku ciężkiego trądziku, ale może wystąpić przy każdej formie trądziku pospolitego1. Ryzyko powstania blizn jest szczególnie wysokie w przypadku torbielowatej postaci trądziku, gdzie zmiany penetrują głęboko w warstwy skóry4.

Przebarwienia

Po ustąpieniu zmian trądzikowych często pozostają przebarwienia pozapalne (post-inflammatory hyperpigmentation – PIH)2. Są to płaskie plamy, które mogą być różowe, czerwone, fioletowe, czarne lub brązowe2.

W przeciwieństwie do blizn, przebarwienia te ostatecznie ustępują samoistnie, choć może to trwać nawet rok lub dłużej2. Osoby z ciemniejszymi typami skóry są bardziej narażone na przebarwienia pozapalne2.

Wpływ psychologiczny

Trądzik może mieć głęboki i długotrwały wpływ psychologiczny na pacjentów, niezależnie od nasilenia choroby2. Badania pokazują, że osoby z trądzikiem mogą doświadczać1:

  • Obniżonej samooceny
  • Niepewności
  • Lęku
  • Depresji
  • W skrajnych przypadkach, myśli samobójczych

U nastolatków z trądzikiem występuje wyższe ryzyko rozwoju depresji niż u nastolatków z okazjonalnymi pryszczami2. Efekty psychologiczne zazwyczaj poprawiają się wraz z leczeniem2.

Kiedy szukać pomocy medycznej

Trądzik często ustępuje samoistnie, ale w niektórych przypadkach konieczna jest konsultacja z lekarzem lub dermatologiem2.

Należy skonsultować się z lekarzem, jeśli11:

  • Masz trądzik umiarkowany lub ciężki, który powoduje guzki pod skórą i przetrwałe pryszcze
  • Trądzik prowadzi do bliznowacenia
  • Trądzik powoduje ciemne plamy
  • Trądzik nie reaguje na dostępne bez recepty środki
  • Trądzik ma duży wpływ na twoją samoocenę i jakość życia

Wczesne leczenie, zanim trądzik rozwinie się do postaci torbieli i guzków, może zapobiec powstawaniu ciężkich ciemnych plam i blizn1. Bez leczenia trądzik może się nasilić1.

Leczenie trądziku wymaga cierpliwości i wytrwałości. Nawet przy odpowiednim leczeniu, poprawa może być stopniowa i mogą wystąpić okresowe zaostrzenia. Jednak przy zastosowaniu nowoczesnych metod, lekarze mogą pomóc w oczyszczeniu skóry praktycznie każdemu3.

    Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acne is most common among teenagers, though it affects people of all ages. […] Effective acne treatments are available, but acne can be persistent. The pimples and bumps heal slowly, and when one begins to go away, others seem to crop up. […] Acne signs vary depending on the severity of your condition: Whiteheads (closed plugged pores), Blackheads (open plugged pores), Small red, tender bumps (papules), Pimples (pustules), which are papules with pus at their tips, Large, solid, painful lumps under the skin (nodules), Painful, pus-filled lumps under the skin (cystic lesions). […] Acne usually appears on the face, forehead, chest, upper back and shoulders.

    https://www.aad.org/public/diseases/acne/really-acne/symptoms
    When you have acne, you can develop any (or a combination) of these breakouts on your skin: […] A whitehead forms when excess oil and dead skin cells build up and plug the opening of a pore. This causes a blemish that is raised and white or flesh colored. […] This type of acne also develops when excess oil and dead skin cells build up inside a pore. As the buildup accumulates, it widens the opening of the pore and you see a blackhead. […] Sometimes excess oil, dead skin cells, and bacteria get trapped inside a pore. The bacteria, which are normally found on our skin, can multiply quickly in the excess oil. As the pore fills with bacteria, inflammation (swelling) develops and a pimple appears. […] When a pore fills with enough excess oil, dead skin cells, and bacteria to cause inflammation (swelling) that goes deep into the skin, an acne nodule or cyst develops. Because these breakouts go deep into the skin, they can feel tender or painful.

    Acne is a common skin condition where the pores of your skin clog. Pore blockages produce blackheads, whiteheads and other types of pimples. Pimples are pus-filled, sometimes painful, bumps on your skin. […] Symptoms of acne on your skin include: Pimples (pustules): Pus-filled bumps (papules). Papules: Small, discolored bumps, often red to purple or darker than your natural skin tone. Blackheads: Plugged pores with a black top. Whiteheads: Plugged pores with a white top. Nodules: Large lumps under your skin that are painful. Cysts: Painful fluid-filled (pus) lumps under your skin. Acne can be mild and cause a few occasional pimples, or it can be moderate and cause inflammatory papules. Severe acne causes nodules and cysts. […] Acne is largely a hormonal condition thats driven by androgen hormones, especially testosterone. This typically becomes active during teenage and young adult years. You might also notice acne forming around the time of your period as a result of hormone activity. Sensitivity to these hormones combined with surface bacteria on your skin and substances released from your bodys glands can result in acne.

    Most teenagers will have pimples at some point. Some only have a few small pimples that soon go away again. Others develop persistent and clearly visible acne. This can be very distressing, particularly in puberty. […] The severity of acne can vary quite a bit. Doctors distinguish between mild, moderate and severe forms of acne. There are also inflammatory and non-inflammatory types of acne. Non-inflammatory acne is a milder type, which most people would refer to as pimples or blackheads rather than acne. […] Unlike normal pimples, acne develops over a longer period of time and stays longer. It sometimes leaves small red marks or scars behind. Normal pimples usually form quickly and then go away again soon afterwards. […] Mild acne: People with mild acne have comedones (blackheads or whiteheads). These are clogged pores in the skin.

    Acne vulgaris is a chronic inflammatory disorder affecting the pilosebaceous unit, typically following a prolonged course. This common skin disorder that can present with both inflammatory and non-inflammatory lesions. Acne vulgaris is a common cutaneous inflammatory disorder of the pilosebaceous unit, which runs a chronic course. The condition commonly manifests with papules, pustules, or nodules primarily on the face, although it can also affect the upper arms, trunk, and back. The severity of this condition can vary, ranging from a mild presentation with only a few comedones to more severe forms characterized by disfiguring inflammatory manifestations, which can lead to hyperpigmentation, scarring, and adverse psychological effects. Acne develops as a result of hypersensitivity of the sebaceous glands to normal levels of circulating androgens. The pathogenesis of acne vulgaris involves the interaction of several host factors, including the stimulation of sebaceous glands by circulating androgens, dysbiosis of the pilosebaceous follicle microbiome, and cellular immune responses. The microcomedo serves as the primary lesion and is the precursor for all clinical manifestations of acne vulgaris. Microcomedones gradually evolve and develop into other acne lesions, which include closed comedones (whiteheads), open comedones (blackheads), and inflammatory papules, pustules, and nodules. The progression of microcomedones into other types of acne lesions has been theorized to involve the following 4 primary pathogenic events: Increased sebum production (seborrhea), follicular hyperkeratinization, C acnes, formerly, Propionibacterium acnes (An anaerobic diphtheroid that naturally exists as part of the skin flora.), and inflammation. The gradual accumulation of keratinous material and sebum converts a micro comedo into a closed comedo. Through continuous distension, the follicular orifice gradually expands, resulting in the formation of an open comedo. Eventually, follicles rupture with the release of bacteria, keratin, and proinflammatory lipids into the surrounding dermis, exacerbating the inflammation with subsequent nodule formation. Acne vulgaris is commonly observed in adolescents and young adults. Its prevalence rates are estimated to range from 35% to over 90% among adolescents. The natural course of this disease can commence as early as ages 7-12 (preadolescent acne) and resolve by the third decade of an individual’s life. However, there are instances where acne can persist into adulthood or even develop for the first time during adulthood. Acne vulgaris is typically diagnosed based on physical examination rather than laboratory tests. The assessment of acne severity depends on multiple factors. The features that must be considered for a comprehensive evaluation of acne severity include the psychological impact of acne on the patient, clinical type of lesions, scarring, draining lesions, or sinus tracts, as well as the patient’s response to treatment. The extent of skin involvement in acne varies greatly, ranging from a few small comedones to many inflamed nodules. Acne can leave various scars after healing, which may present as depressed scars or hypertrophic and keloidal scars. Acne vulgaris can be associated with certain rare syndromes, including SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, and osteitis) with features of inflammatory arthritis or osteitis, particularly of the anterior chest wall. The overall prognosis of acne is generally good with appropriate treatment. While acne may not be life-threatening, it can have significant and lasting psychosocial effects. Individuals with acne and acne scars often experience increased levels of anxiety and depression.

    Acne is a common skin condition causing pimples and other abnormalities on the face and upper torso. […] Bumps, such as blackheads, whiteheads, pimples, cysts, and sometimes abscesses, form on the skin, usually on the face, chest, shoulders, or back. […] Acne is characterized by many types of skin abnormalities (lesions). They vary in size and severity, and some go deeper into the skin than others do: […] A pimple is an inflamed whitehead. The blocked sebum-filled hair follicle promotes overgrowth of the bacterium Cutibacterium acnes, which is normally present in the hair follicle. This bacterium breaks down the sebum into substances that irritate the skin. The resulting inflammation causes the skin bumps that are commonly known as acne pimples. Deeper inflammation causes cysts and sometimes an abscess.

    Acne has a lifecycle, or more accurately, a progression of stages, and understanding these stages is pertinent to their management. Each stage of acne has its challenges, and it is critical to manage them effectively to prevent the progression of this skin condition. […] You may not even be aware that the acne process has started at this stage, as it doesn’t exhibit the typical inflammation that often accompanies acne breakouts. This initial phase can be deceiving, leading individuals to overlook the early signs of acne development. Non-inflammatory or comedonal acne represents the initial stage of acne development. This type typically originates from minor obstructions within the hair follicles, leading to the formation of comedones. […] You can observe open and closed comedones on your skin. Blackheads, known as open comedones, appear as dark spots on your skin due to sebum oxidation in the follicle. On the other hand, whiteheads, also called closed comedones, are follicles closed from the skin’s surface, leading to a different appearance than blackheads.

Because when youre trying to treat acne, understanding whats happening to your skin is the first step toward a clearer complexion. […] Before you can even see whats happening, microscopic amounts of oil and debris can become trapped inside your pores. The result are microcomedones undetectable to the naked eye but essentially, baby blemishes. […] The buildup of sebum and dead cells essentially forms a plug that blocks the pore opening, leading to even more buildup.

    Acne vulgaris is the most common skin disease in industrial nations. It usually begins during puberty, in line with hormone changes, and may persist into later adulthood. Approximately 80-90% of young people are affected to some degree with blemishes and 20-30% of these people will seek medical support. There are also increasing numbers of adults, particularly women, experiencing acne later in life. […] With acne, skin becomes oily and open and closed comedones (black and whiteheads) appear on the face and often the neck, shoulders, chest and back too. In moderate and severe acne, skin becomes reddened and inflamed papules and pustules develop. Acne can be emotionally distressing, annoyingly persistent and can lead to post-inflammatory hyperpigmentation (PIH) and/or long-term scarring. […] The consequence is reddened and inflamed skin. In severe cases of acne, the follicle wall bursts in the late phase of inflammation. Lipids, fatty acids, corneocytes, bacteria and cell fragments are released, causing extended and deep inflammations in the adjacent tissue.

    Acne in adults is also called postadolescent acne. It can be persistent, with onset during teenaged years, or late onset beginning after the age of 25 years. Acne affects up to 15% of women, but is usually reported to be less common in men. […] Adult acne can be predominantly inflammatory, with papules and pustules, or predominantly comedonal, often with many large closed comedones (whiteheads). Deep inflammatory lesions and macrocomedones may result in scarring. […] Adult acne usually presents as acne vulgaris (common acne). But it often has the following characteristics. Acne is very persistent in some people and may continue into the 30s and 40s. It tends to be mild to moderate in severity. Affected women often complain of enlarged pores. Some reports have suggested it is more common in people with olive skin (skin phototype IV). Inflammatory lesions are common on the jawline and neck but may be seen anywhere on face, neck, chest or back. Premenstrual flares are common. Macrocomedones (large whiteheads) are more common than in younger individuals. They are mostly found on chin, cheeks and forehead. Environmental factors have been associated with comedonal acne, particularly oily face creams and smoking. Dietary factors, particularly refined carbohydrates (sugars), are blamed for increasing prevalence of acne. Onset of inflammatory acne is often attributed to stress.

    Adult acne can still happen and is a common condition among women – even after age 30. […] Women are more prone to adult breakouts compared to men. In fact, a Rutgers Robert Wood Johnson Medical School study finds about half of women in their 20s, one-third of women in their 30s and one-quarter of women in their 40s will be bothered by breakouts. […] “Adult-onset acne is more prevalent in women and more likely to appear along the jawline than in the “T-zone” of the forehead, nose and chin,” said Clarissa Yang, MD, Chief of Dermatology at Tufts Medical Center. “Jawline acne in women can suggest a hormonal imbalance.” […] The hormonal imbalance that results in jawline acne is thought to be caused by a relative increase in androgen levels, explained Dr. Yang. Androgens are male hormones which can result in increased oil gland production and clogging of pores.

    Acne occurs mainly during puberty, when the sebaceous glands are stimulated by increased hormone levels, especially the androgens (such as testosterone), resulting in excessive sebum production. By a person’s early to mid 20s, hormone levels usually have decreased enough that acne lessens or disappears. However, some women have acne into their 40s. […] Most acne occurs on the face but is also common on the neck, shoulders, back, and upper chest. […] There are 3 levels of acne severity: Mild acne, Moderate acne, Severe acne.
