If acne reliably appears on your chin and around your mouth every month before your period, it's likely hormonal acne.
Hormonal acne develops when fluctuations in androgens (male hormones) stimulate the sebaceous glands. It's common not only in puberty but also among adults in their 20s–40s, especially women.
Characteristics of hormonal acne
There are signs that distinguish it from ordinary acne.
- Location: Chin, around the mouth, jawline, neck
- Cyclical pattern: Worsens from 2 weeks before to right before menstruation
- Form: Deep, firm inflammatory acne (papules and nodules)
- Recurrence: Keeps appearing in the same spot
Why does it worsen before your period?
In the second half of the menstrual cycle (the luteal phase), progesterone rises and estrogen falls. As the relative influence of androgens grows, sebum production increases and clogged pores lead to acne.
| Phase | Hormonal state | Skin condition |
|------|-----------|---------|
| Right after menstruation | Estrogen rising | Stable, clear skin |
| Ovulation | Hormonal balance | Relatively good |
| 2 weeks before menstruation | Progesterone rising | Sebum begins to increase |
| Right before menstruation | Androgen influence ↑ | Acne worsens |
How to manage hormonal acne
1. Consistent ingredient care (most important)
With hormonal acne, responding "after it erupts" is too late. Manage it daily, consistently, regardless of your cycle.
- Niacinamide: Sebum control + inflammation relief
- Salicylic acid (BHA): Focused application on the chin and around the mouth
- Azelaic acid: Anti-inflammatory + improves hyperpigmentation, relatively safe even during pregnancy
- Retinoids: Use in the evening; suppresses follicular hyperkeratinization
2. Lifestyle habits
- Reduce dairy and high-GI foods (sugar, refined carbs)
- Get at least 7 hours of sleep (sleep deprivation raises cortisol)
- Manage stress
3. Professional treatment (for recurring/severe cases)
If lifestyle management doesn't resolve it, you may consider oral contraceptives (hormone regulation) or spironolactone prescribed by a dermatologist. A specialist consultation is essential.
Can cosmetics regulate hormones?
Cosmetics address sebum, dead skin, and inflammation on the skin's surface, but they cannot regulate hormones themselves. Therefore, hormonal acne should be approached with a combination of ingredient care (topical) + lifestyle habits + professional treatment when needed.
Frequently asked questions
Is chin acne always due to hormones?
It's a common cause of acne on the chin and around the mouth, but mask-wearing (maskne) and the habit of frequently touching your face can also be causes.
Should hormonal acne also not be popped?
Correct. Hormonal acne is deep and inflammatory, so popping it tends to leave scars.
Is it enough to manage only before my period?
No. Acne forms inside the pores 2–3 weeks before it becomes visible on the surface, so consistent everyday care is needed to prevent it.
