You’re no longer a teenager, you take careful care of your skin - and yet those pimples keep coming back again and again. Especially along the jawline, on the chin, or extending down toward the neck. And always during the same week of the month. If that sounds familiar, there’s a good chance it’s not about inadequate cleansing. It’s about hormones.
What is hormonal acne?
Hormonal acne is a skin condition that occurs when fluctuations in the body’s hormones - primarily androgens - increase sebum production in the skin. This creates an environment where pores become blocked and bacteria thrive. Hormonal acne typically appears in the lower third of the face: the jawline, chin, and neck. It usually follows the menstrual cycle and returns in a predictable pattern, no matter what you apply to your skin.
This sets it apart from classic teenage acne, which spread across the entire face and was caused by a more general hormonal increase during puberty. Hormonal acne in adult women is more localized, deeper, and much more persistent - because it is driven by cyclical hormonal fluctuations, not a single surge during puberty.
5 signs your acne is hormonal
Most people know the classic teenage image of acne - scattered pimples on the nose and forehead. Hormonal acne looks different. Here are five signs that clearly point to it:
1. It appears along the jawline and on the chin. Hormonal acne has a characteristic pattern in the lower third of the face. Pimples along the jawline, on the chin, and extending down toward the neck are the strongest sign that hormones are involved. These areas have a high density of androgen-sensitive sebaceous glands that react more strongly to hormonal fluctuations than the forehead and nose.
2. Pimples are deep and tender to the touch. Hormonal pimples form deeper in the skin than surface acne. They are often hard, highly inflamed, and painful - those "nodules" that feel as if they’re cemented under the skin and rarely come to the surface.
3. They appear in cycles. Do you notice your skin getting worse one to two weeks before your period and improving again afterward? This is a classic pattern for hormonal acne, driven by falling estrogen and rising progesterone during the luteal phase. Your skin isn’t constantly bad - it follows a pattern you can learn to recognize over time.
4. It started in adulthood. Hormonal acne typically affects women in their 20s, 30s, and 40s — often with no history of acne during their teenage years. A systematic review article from 2025 (Telkkälä et al.) shows that up to 54 percent of women aged 25 to 40 experience some form of acne.
5. It doesn't respond to conventional acne treatments. Have you tried benzoyl peroxide, salicylic acid, and drying products — without lasting results? This is typically because these products don't address the underlying cause. Hormonal acne requires a different approach from puberty-related acne.
Why hormones make your skin oilier — and more vulnerable
Androgens are a group of hormones that includes testosterone and dihydrotestosterone (DHT). They stimulate the sebaceous glands in the skin to produce more sebum. According to research, DHT is 5-10 times more potent than testosterone, so even a small increase in androgen levels can have a major effect on the skin's oil production.
Insulin also plays a central role. A diet rich in fast-acting carbohydrates increases the release of insulin and IGF-1 (insulin-like growth factor), both of which further stimulate the sebaceous glands. This explains why hormonal acne can be affected by your dietary habits, not just your hormone cycle. To learn more about the connection between diet and skin reactions, read our article about food and skin triggers for perioral dermatitis — many of the mechanisms are comparable.
When sebum production increases, pores become more easily clogged. The bacterium Cutibacterium acnes thrives in the low-oxygen, oil-rich environment. The result is inflammation, redness, and visible pimples — most often exactly where your skin is most sensitive to androgen signals.
Key figures about hormonal acne:
🔬 54% of women aged 25-40 experience acne (Telkkälä et al., 2025)
🔬 DHT is 5-10× more potent than testosterone at stimulating the sebaceous glands
🔬 Over 90% of cases of hyperandrogenism in women with acne are associated with PCOS
🔬 Up to 90% improvement is seen with hormonal treatment in women (Elsaie, 2016)
The 3 most common mistakes with hormonal acne
Many of the strategies that work against teenage acne work directly against their intended purpose when it comes to hormonal acne. Here are the three mistakes we see most often:
Mistake 1: Over-cleansing and drying out the skin. It’s natural to cleanse more and use stronger products when your skin breaks out. But with hormonal acne, cleansing is rarely the problem. Strong products and frequent exfoliation can damage the skin barrier — and when the barrier is damaged, an inflammatory response is activated that worsens hormonal breakouts. You can read more about what happens when the skin barrier is compromised, and why fighting your skin with overly aggressive products backfires.
Mistake 2: Treating the symptoms instead of the cause. Products designed to reduce bacteria and tighten pores do not address the hormonal cause. The routine should support the skin barrier and calm inflammation — not fight the skin as if it were a hygiene problem.
Mistake 3: Switching products too quickly. Hormonal acne follows a 3-4 week cycle. Many people switch products after two weeks without visible improvement — precisely because they haven’t given the routine time to cover a full cycle. Give a new routine at least 6-8 weeks, ideally two full menstrual cycles, before assessing whether it works.
Cleanse gently — protect the skin barrier
Our gentle foaming facial cleanser with betaine removes dirt and excess sebum without stripping the skin’s natural moisture balance — exactly what hormonally vulnerable skin needs.

The most important principle is simple: support the skin barrier, calm inflammation, and be consistent. Here’s a routine you can build on:
Morning: Cleanse with a gentle foaming cleanser that does not disrupt the skin’s pH or moisture balance. Betaine — a natural osmolyte — is an ingredient that actively protects the moisture balance during cleansing. Finish with a lightweight, non-comedogenic day cream and always use SPF 50. UV exposure can worsen acne scars and prolong the healing time of inflamed pimples.
Evening: Cleanse again with the gentle cleanser. During active periods — typically the 7-10 days before your period — you can apply ZZ-Creme directly to inflamed pimples. ZZ-Creme contains zinc and sulfur, both proven effective for inflammatory skin conditions, and targets active inflammation without drying out the surrounding skin.
During calmer periods: Focus on strengthening the skin barrier. A lightweight moisturising day cream with niacinamide, hyaluronic acid and lactic acid supports the skin’s ability to regulate itself — and reduces vulnerability to the next hormonal breakout.
Ingredients that help — and those to avoid
Not all ingredients are created equal when it comes to hormonal acne. Here’s what research suggests:
Ingredients that help:
Niacinamide (B3) is one of the best-documented ingredients for acne. Studies show that 2-5% niacinamide reduces sebum production, calms redness and inflammation, and strengthens skin barrier function by increasing the production of intercellular lipids in the outermost layer of the skin. It is an ingredient that works on several of the mechanisms that drive hormonal acne.
Zinc is naturally anti-inflammatory and inhibits the growth of bacteria that drive acne inflammation. It is one of the key ingredients in ZZ-Creme and has a documented effect on inflamed skin conditions.
Betaine (osmolyte) actively protects the skin barrier during cleansing and prevents moisture from being drawn out of the skin — important for maintaining the integrity of the skin barrier during daily cleansing.
Hyaluronic acid attracts moisture and keeps the skin soft and supple without adding oils that can clog pores.
Ingredients to avoid with hormonal acne: Heavy, occlusive creams with mineral oils or certain silicones can clog already vulnerable pores. High concentrations of alcohol dry out the skin and damage the skin barrier. Harsh physical exfoliants during active breakouts can worsen inflammation. And always check your makeup products — many foundations and concealers contain comedogenic ingredients that contribute to clogged pores alongside hormones. See how hormones affect sensitive skin in a broader context for inspiration.
Pro tip: Always check the comedogenic rating of your products — especially makeup. Many foundations and primers contain oils and waxes that clog pores and worsen hormonal breakouts. A comedogenic ingredient is not a problem for all skin types, but if it’s relevant to you, check a reputable comedogenicity database before introducing a new product.
When should you seek medical help?
Hormonal acne can often be managed effectively with a well-considered skincare routine. But there are situations where it’s important to seek professional help:
See your primary care doctor or a dermatologist if your breakouts are severe, deep, and leave scars. Seek help if you have other signs of hormonal imbalance — irregular periods, sudden hair loss on the scalp, or excessive facial or body hair. PCOS (polycystic ovary syndrome) is associated with over 90 percent of cases of hyperandrogenism in women with acne and requires medical evaluation. If needed, your doctor can order blood tests to check hormone levels and may refer you for hormonal treatment such as birth control pills or spironolactone, both of which have been shown to be effective for hormonal acne. Also seek help if your breakouts negatively affect your well-being and self-image — that is a valid reason to seek treatment.
Frequently asked questions about hormonal acne
What is hormonal acne?
Hormonal acne is a form of adult acne caused by hormonal fluctuations — primarily androgens, which increase sebum production in the skin. It typically appears along the jawline and on the chin and often follows the menstrual cycle. It is most common in women in their 20s, 30s, and 40s, and differs from puberty-related acne, which is more generally spread across the face.
Why does hormonal acne appear along the jawline?
Androgens affect the sebaceous glands unevenly across the face. The jawline, chin, and lower cheeks have a particularly high density of androgen-sensitive sebaceous glands that respond most strongly to hormonal fluctuations. This is the direct cause of the classic jawline pattern, which is the clearest sign that acne is hormonally driven.
Can you develop hormonal acne as an adult if you didn’t have it as a teenager?
Yes, and it’s actually very common. Hormonal acne is primarily an adult problem. A 2025 systematic review shows that up to 54 percent of women aged 25 to 40 experience acne. It can first appear in your 20s or 30s — even if you had completely clear skin as a teenager.
Is PMS acne the same as hormonal acne?
PMS breakouts are a form of hormonal acne. They typically appear 1-2 weeks before menstruation, when estrogen levels fall and progesterone levels rise during the luteal phase. Many women find that their breakouts follow this exact pattern — and it’s one of the clearest signs that their acne is hormonally driven, not caused by a skincare problem.
Can diet affect hormonal acne?
Yes. Research shows that a diet rich in refined carbohydrates increases insulin and IGF-1, both of which stimulate sebum production. Dairy products, especially skim milk, have been associated with increased acne in some studies — probably due to growth factors in milk proteins. Reducing sugar and processed carbohydrates is one of the dietary changes with the strongest evidence base.
What are the best ingredients for hormonal acne?
Niacinamide (B3) is one of the best-documented ingredients — it reduces sebum production, calms inflammation, and strengthens the skin barrier. Zinc is an effective anti-inflammatory and antibacterial ingredient. Betaine and hyaluronic acid support the skin barrier, which is easily compromised during hormonal breakouts. Salicylic acid can be used cautiously to clear clogged pores during calmer periods.
When should I see a doctor about hormonal acne?
See a doctor if your breakouts are severe and leave scars, if you have other signs of hormonal imbalance such as irregular periods or hair loss, or if you do not see improvement after 3 months of a consistent routine. PCOS should be investigated if persistent severe acne occurs alongside hormonal symptoms. Your doctor can refer you for hormonal treatment or to a dermatologist.
