You keep dealing with breakouts that come back again and again, even though you've changed your routine, tried the serums everyone raves about on TikTok and invested in popular Korean products. Sometimes they clear up fast, other times they hurt and leave marks behind. The cause is what makes the difference. Hormonal acne and bacterial acne look similar on the surface, but the mechanisms behind them are different, and the treatment has to match.
This article is for informational purposes only and does not replace a dermatological consultation. If the lesions persist or get worse, book an appointment for a proper diagnosis and a personalised plan.
What hormonal acne is and how to recognise it
Hormonal acne develops against a background of hormonal fluctuations, particularly androgens. These hormones stimulate the sebaceous glands and increase sebum production [1]. Excess sebum clogs the pores and encourages deep inflammation.
In many women between 20 and 50, breakouts intensify before menstruation, during stressful periods or after stopping contraceptives [1]. If you notice painful spots on your chin and jawline that return every month, that's a clear clue.
What it usually looks like:
- Deep nodules or cysts, tender to the touch
- Located along the jawline, chin and sometimes the neck
- Fewer blackheads
- Post-inflammatory pigmentation marks that linger
The advantage of identifying it correctly: you can address the internal cause and reduce recurrence. The downside: it responds more slowly to treatments applied only on the surface.
A combined strategy is needed. A dermatologist may recommend combined oral contraceptives, spironolactone or, in severe forms, isotretinoin. These options can have side effects and require close medical monitoring. Don't start them without a recommendation.
Topically, retinoids, azelaic acid and niacinamide help control inflammation and regulate sebum. For example, an azelaic acid serum such as Azelaic Acid Serum can reduce redness and post-acne marks, and works well in an evening routine if your skin tolerates the ingredient.
Another useful step is choosing products based on how your skin reacts. If you notice excess sebum, congested pores and recurring inflammation, a product like Zinc PCA Facial Serum can be worked into a carefully built routine. Use it alongside the ingredients your specialist recommends. Introduce products gradually and keep track of how your skin responds, especially when acne has a hormonal component.
What bacterial acne is and how it differs
Bacterial acne involves the overgrowth of the bacterium Cutibacterium acnes inside clogged pores. The bacterium is part of the skin's normal flora, but it multiplies quickly in the presence of sebum and built-up dead cells [2].
It shows up most often in the T-zone – forehead, nose, upper cheeks – and includes pustules with visible pus or numerous comedones (blackheads and whiteheads). For instance, if you notice small, superficial breakouts after workouts or after using a very occlusive foundation, there's most likely a bacterial component.
The advantage: it responds well to the right topical ingredients. The limitation: it comes back if you don't keep excess sebum and pore congestion under control.
Useful ingredients include salicylic acid, benzoyl peroxide and retinoids. If you want to better understand how BHA works, read about salicylic acid and its benefits. Salicylic acid penetrates the pores, dissolves sebum plugs and reduces inflammation.
For a balanced routine, choose products made for oily skin and gradually introduce chemical exfoliants with AHA or BHA. Use them 2-3 times a week, not daily at first, to avoid irritation.
Hormonal acne vs. bacterial acne – a clear comparison
| Criterion | Hormonal acne | Bacterial acne |
|---|---|---|
| Location | Chin, jawline | T-zone |
| Type of lesions | Deep nodules, cysts | Pustules, papules, comedones |
| Link to the menstrual cycle | Frequently present | Absent |
| Response to topicals | Slow, partial | Good, visible in 6-8 weeks |
| Internal component | Frequent | Rarer |
Many women have a mixed form. Hormones increase sebum, and bacteria take advantage of the environment created. If you have both painful nodules along the jawline and blackheads on your forehead, talk to your dermatologist about a combined plan.

How to choose the right treatment
Start with a realistic assessment of your symptoms. Note where the lesions appear, whether they're painful and whether they line up with your menstrual cycle. Watch how quickly your skin reacts to an exfoliant or a soothing serum.
For hormonal acne:
- See a dermatologist or endocrinologist for tests if the breakouts persist.
- Use retinoids or azelaic acid to control inflammation.
- Reduce stress and prioritise sleep; lack of rest affects hormonal balance.
For bacterial acne:
- Cleanse your skin gently morning and evening.
- Introduce salicylic acid or benzoyl peroxide.
- Avoid very occlusive foundations; choose lightweight BB or CC creams suited to oily skin.
Whatever the type, apply sun protection daily. SPF prevents post-inflammatory marks from getting worse [3].
Be careful about layering active ingredients. If you use retinol, don't apply strong exfoliants on the same evening. Excessive irritation can make inflammation worse. During pregnancy or breastfeeding, avoid retinoids and discuss any new product with your doctor.
The skincare routine that supports acne-prone skin
A well-structured routine helps skin stay balanced, whatever the cause of the acne.
- Gentle cleansing – a gel with a pH close to that of the skin.
- Active treatment – BHA, retinol, azelaic acid or niacinamide, matched to your type of acne.
- Hydration – choose lightweight formulas with peptides or collagen to support the skin barrier.
- Sun protection – every day, including in the cold season.
Korean products from brands such as Medicube, Dr. Althea or Biodance often include ingredients like peptides or PDRN (polydeoxyribonucleotide), which support skin regeneration. They don't treat the hormonal or bacterial cause, but they help repair the barrier and fade post-acne marks.
Don't squeeze your spots. You increase the risk of scarring and infection. Change your pillowcases regularly and clean your makeup brushes weekly.
When to seek medical help
Book a consultation if:
- The lesions are painful and deep
- Scars or persistent marks appear
- You see no improvement after 8-12 weeks of a correct routine
- Acne is affecting your self-esteem
Your doctor may recommend hormone tests or systemic treatments, depending on the picture. Early intervention reduces the risk of permanent scarring.

Frequently asked questions
Can I have hormonal acne if I'm over 30?
Yes. Adult acne is frequently linked to hormonal fluctuations and often appears on the jawline and chin. Age doesn't rule out a hormonal component.
How long until I see results?
With topical treatments for bacterial acne, many people see improvement after 6-8 weeks. With hormonal therapies, results can take 3-6 months, under medical supervision.
Can I combine salicylic acid with retinol?
You can alternate them – for example BHA in the morning and retinol in the evening, or on different days. Applying them at the same time can irritate the skin. Introduce ingredients gradually and watch how your skin reacts.
