Why adults get acne
Adult acne (acne in people over 25) affects up to 15% of women and 5% of men. It occurs when sebaceous glands overproduce oil (sebum), which clogs pores and creates an environment where Cutibacterium acnes bacteria thrive, triggering inflammation. In adults, the main drivers differ from teen acne: hormonal fluctuations are the leading cause in women, particularly around the menstrual cycle, during perimenopause, and in polycystic ovary syndrome (PCOS). Stress (which raises androgens), comedogenic skincare products, and certain medications (lithium, corticosteroids, some oral contraceptives) are other common triggers.
Adult acne tends to appear on the lower face (jaw, chin, neck) rather than the forehead — a pattern strongly associated with hormonal causes. Comedonal acne (blackheads and whiteheads only) responds well to topical retinoids. Inflammatory acne (red papules and pustules) typically requires topical antibiotics or benzoyl peroxide. Nodular or cystic acne — deep, painful lesions — may need oral antibiotics or isotretinoin, and leaves the highest risk of scarring if untreated.
Key facts
- ✓Topical retinoids (tretinoin, adapalene) are the first-line treatment for most types of adult acne
- ✓Hormonal acne in women often responds well to combined oral contraceptives or spironolactone
- ✓Isotretinoin (Roacutan) is the most effective treatment for severe cystic acne but requires close monitoring
- ✓Over-washing and harsh scrubs worsen adult acne by damaging the skin barrier
- ✓Dietary factors (high-glycemic foods, dairy) may exacerbate acne in susceptible individuals

Topical treatments: Tretinoin (0.025–0.1%) and adapalene are retinoids that normalize cell turnover and prevent clogged pores. They require consistent use for 8–12 weeks before full results appear and cause initial dryness and peeling — this is normal. Topical clindamycin or erythromycin (ideally combined with benzoyl peroxide to prevent resistance) target the bacterial component. Benzoyl peroxide (2.5–5%) has both antimicrobial and comedolytic effects and is available OTC, but can bleach fabrics.
Systemic treatments: Oral doxycycline or minocycline (100 mg/day) for 3–6 months treat moderate-to-severe inflammatory acne. Combined oral contraceptives (ethinyl estradiol + drospirenone or levonorgestrel) reduce androgenic stimulation of sebaceous glands in women. Isotretinoin (0.5–1 mg/kg/day for 4–6 months) produces remission in severe cystic acne in 85% of cases but is teratogenic and requires pregnancy prevention measures and liver monitoring.

Book nowSkincare routine for acne-prone skin
A simple, non-irritating skincare routine is as important as medication. Use a gentle, non-comedogenic cleanser twice daily (avoid scrubbing). Apply a non-comedogenic moisturizer — even oily skin needs hydration, especially when using retinoids. Use SPF 30+ sunscreen daily (retinoids increase sun sensitivity). Avoid picking or squeezing lesions, which deepens inflammation and worsens scarring. Change pillowcases frequently and avoid touching your face.
Check all skincare and makeup products for "non-comedogenic" labeling. Ingredients like mineral oil, lanolin, and certain silicones can clog pores in acne-prone skin. Niacinamide (5–10%) is a well-tolerated ingredient that reduces inflammation and sebum production without irritation. Hyaluronic acid is a safe humectant that hydrates without clogging pores.
FAQ
Can a general physician treat adult acne?
Yes, for mild to moderate acne. A general physician can prescribe topical retinoids, topical antibiotics, benzoyl peroxide, and oral doxycycline. For severe cystic acne or cases requiring isotretinoin, dermatology referral is appropriate.
Is there a hormonal test I should get?
If you have acne with irregular periods, hirsutism, or hair loss, the doctor may order testosterone, DHEA-S, and LH/FSH to evaluate for PCOS. For most adult acne, hormonal tests aren't necessary.
How long does acne treatment take?
Most topical treatments require 8–12 weeks for noticeable results. Oral antibiotics typically show improvement in 4–6 weeks. Patience and consistency are essential — stopping treatment too early is the most common reason for failure.
Can an online doctor prescribe tretinoin or isotretinoin in Peru?
Yes. A Delvir physician can prescribe tretinoin and topical antibiotics online after evaluating your case. Isotretinoin requires a more thorough assessment due to its monitoring requirements — the doctor will guide you through what's needed.
Conclusion
Adult acne is highly treatable with the right approach. The key is an accurate assessment of the type and cause, followed by evidence-based treatment and a consistent skincare routine. Don't rely on trial-and-error with OTC products — a medical consultation gets you to the right treatment faster.
