You are no longer a teenager, take good care of your skin — yet those pimples keep coming back again and again. Especially along the jawline, on the chin, or down toward the neck. And always in the same week of the month. If this sounds familiar, there is a good chance it is not about poor cleansing. It is 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: jawline, chin, and neck. It usually follows the menstrual cycle and returns in a predictable pattern, regardless of what you apply topically.
This distinguishes it from classic teenage acne, which spread across the entire face and was caused by a more general hormone increase during puberty. Hormonal acne in adult women is more focused, deeper, and much more persistent — because it is driven by cyclical hormonal fluctuations, not a single puberty surge.
5 signs that your acne is hormonal
Most people are familiar with the classic teenage acne picture — scattered pimples on the nose and forehead. Hormonal acne looks different. Here are the five signs that clearly point in that direction:
1. It is located 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 down toward the neck are the strongest signal 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 develop deeper in the skin than superficial acne. They are often hard, very inflamed, and painful — the "nodules" that feel as if they are cemented under the skin and rarely come to the surface.
3. They appear cyclically. Do you notice your skin worsening one to two weeks before your menstruation and then improving afterward? This is a classic pattern of hormonal acne, driven by decreasing estrogen and increasing progesterone in the luteal phase. The skin is not 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 classic acne treatments. Have you tried benzoyl peroxide, salicylic acid, and drying products—without lasting effect? This is typically because these products don’t address the underlying cause. Hormonal acne requires a different approach than puberty-related acne.
That’s why hormones make your skin oilier—and more vulnerable
Androgens are a group of hormones that include 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 significant effect on the skin’s oil production.
Insulin also plays a central role. A diet high in fast carbohydrates increases the secretion of insulin and IGF-1 (insulin-like growth factor), both of which further stimulate the sebaceous glands. This explains why hormonal acne can be influenced by your diet, not just your hormonal cycle. If you want to learn more about the connection between diet and skin reactions, you can read our article on food and skin triggers in perioral dermatitis—many of the mechanisms are comparable.
When sebum production increases, pores are more easily blocked. The bacterium Cutibacterium acnes thrives in the oxygen-poor, fatty environment. The result is inflammation, redness, and visible pimples—usually exactly where your skin is most sensitive to androgen signals.
Key facts about hormonal acne:
🔬 54% of women aged 25-40 experience acne (Telkkälä et al., 2025)
🔬 DHT is 5-10× more potent than testosterone in stimulating the sebaceous glands
🔬 Over 90% of hyperandrogenism cases 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 for teenage acne have the opposite effect on hormonal acne. Here are the three most common mistakes we see:
Mistake 1: Over-cleansing and drying out the skin. It is a natural reaction to cleanse more and use stronger products when the 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 compromised, an inflammatory response is triggered that worsens hormonal breakouts. You can read more about what happens when the skin barrier is compromised, and why it backfires to fight the skin with overly aggressive products.
Mistake 2: Treating symptoms rather than the cause. Products designed to reduce bacteria and tighten pores do not address the hormonal cause. The routine must support the skin barrier and reduce inflammation — not fight the skin as if it were a cleaning problem.
Mistake 3: Changing products too quickly. Hormonal acne follows a 3-4 week cycle. Many switch products after two weeks without visible improvement — precisely because they haven’t given the routine time to complete a full cycle. Give a new routine at least 6-8 weeks, preferably two full menstrual cycles, before assessing whether it works.
Cleanse gently — protect the barrier
Our mild foaming facial cleanser with betaine removes dirt and excess sebum without stripping the skin’s natural moisture balance — exactly what hormonally sensitive skin needs.
See the facial cleanser →How to build a routine that helps with hormonal acne
The most important principle is simple: support the barrier, reduce inflammation, and be consistent. Here is a routine you can build on:
Morning: Cleanse with a mild foaming cleanser that does not disrupt the skin’s pH or moisture balance. Betaine — a natural osmolyte — is an ingredient that actively protects moisture balance during cleansing. Finish with a light, non-comedogenic day cream and always SPF 50. UV exposure can worsen acne scars and prolong healing time of inflamed pimples.
Evening: Cleanse again with the gentle cleanser. During active periods — typically the 7-10 days before menstruation — you can apply ZZ-Creme locally directly on inflamed pimples. ZZ-Creme contains zinc and sulfur, both proven effective for inflamed skin conditions, and targets active inflammation without drying out the surrounding skin.
During calmer periods: Focus on strengthening the skin barrier. A light hydrating 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 you should avoid
Not all ingredients are created equal when it comes to hormonal acne. Here is what research points to:
Ingredients that help:
Niacinamide (B3) is one of the most well-documented ingredients for acne. Studies show that 2-5% niacinamide reduces sebum production, calms redness and inflammation, and strengthens the skin barrier function by increasing the production of intercellular lipids in the outer skin layer. It is an ingredient that works on several mechanisms driving hormonal acne.
Zinc is naturally anti-inflammatory and inhibits the growth of bacteria that drive acne inflammation. It is one of the core ingredients in ZZ-Creme and has documented effects 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 skin barrier’s integrity with 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 and damage the skin barrier. Strong physical exfoliants during active breakouts increase inflammation. And always check your makeup products — many foundations and concealers contain comedogenic ingredients that contribute to clogged pores alongside hormones. See here for inspiration on how hormones affect sensitive skin in a broader context.
Pro tip: Always check the comedogenic rating of your products — especially in makeup. Many foundations and primers contain oils and waxes that block pores and worsen hormonal breakouts. A comedogenic ingredient is not a problem for all skin types, but if relevant, you should check a reputable comedogenic database before introducing a new product.
When should you seek medical help?
Hormonal acne can often be well managed with a carefully considered skincare routine. But there are situations where it is important to seek professional help:
See your general practitioner or a dermatologist if the breakouts are severe, deep, and leave scars. Seek help if you have other signs of hormonal imbalance — irregular menstruation, sudden hair loss on the scalp, or excessive hair growth on the face or body. PCOS (polycystic ovary syndrome) is associated with over 90 percent of hyperandrogenism cases in women with acne, and it requires medical evaluation. Your doctor can order blood tests for hormone levels if needed and possibly refer you for hormonal treatment such as birth control pills or spironolactone, both of which are documented to be effective for hormonal acne. Also seek help if the breakouts negatively affect your well-being and self-image — this is a legitimate reason to seek treatment.
Frequently asked questions about hormonal acne
What is hormonal acne?
Hormonal acne is a form of adult acne that occurs due to hormonal fluctuations — primarily androgens that increase sebum production in the skin. The condition typically appears on the jawline and chin and usually 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 on the jawline?
Androgens affect the sebaceous glands in the face unevenly. The jawline, chin, and lower cheeks have a particularly high density of androgen-sensitive sebaceous glands that react most strongly to hormonal fluctuations. This is the direct cause of the classic jawline pattern, which is the clearest sign that the acne is hormonally driven.
Can you get hormonal acne as an adult without having had it as a teenager?
Yes, and it is actually very common. Hormonal acne is primarily an adult issue. A systematic review from 2025 shows that up to 54 percent of women between 25 and 40 years old experience acne. It can debut in the 20s or 30s — even in women who had completely clear skin during their teenage years.
Are PMS pimples the same as hormonal acne?
PMS pimples are part of hormonal acne. They typically appear 1-2 weeks before menstruation, when estrogen drops and progesterone rises in the luteal phase. Many women experience breakouts that precisely follow this pattern — and this is one of the clearest signs that the acne is hormonally driven, not caused by a skincare problem.
Can diet affect hormonal acne?
Yes. Research shows that a diet high in fast carbohydrates increases insulin and IGF-1, both of which stimulate sebum production. Dairy products, especially skim milk, are in some studies associated with increased acne — likely due to growth factors in milk proteins. Reducing sugar and processed carbohydrates is one of the dietary adjustments with the best evidence base.
What are the best ingredients for hormonal acne?
Niacinamide (B3) is one of the most well-documented ingredients — it reduces sebum production, calms inflammation, and strengthens the skin barrier. Zinc is an effective anti-inflammatory and antibacterial agent. Betaine and hyaluronic acid support the skin barrier, which is easily compromised during hormonal outbreaks. Salicylic acid can be used cautiously to clear clogged pores during calm periods.
When should I see a doctor for hormonal acne?
See a doctor if the outbreaks are severe and leave scars, if you have other signs of hormonal imbalance such as irregular menstruation or hair loss, or if you do not see improvement after 3 months of consistent routine. PCOS should be investigated in persistent severe acne combined with hormonal symptoms. Your doctor can refer you for hormonal treatment or to a dermatologist.
