Why adults get acne

Adult acne is acne that lasts past the teen years or starts in adulthood. It means it can resist standard treatment, and in women hormonal therapies are of special value. Adult female acne affects 12 to 54% of women across studies and is persistent, late onset or recurrent; stress, diet, tobacco and cosmetics can trigger it. Check which type yours is.

Over-the-Counter (OTC) Active Ingredients

OTC products may hold benzoyl peroxide at 2.5 to 10% or salicylic acid at 0.5 to 2%. Adapalene 0.1% gel is OTC since 2016, and since May 2026 so is a gel of adapalene 0.1% with benzoyl peroxide 2.5%, for ages 12 and up.

Prescription & Clinical Treatments

Ranks 3 to 9 need a prescription, so ask your doctor about them. In the SAFA trial of 410 women, spironolactone beat a placebo at 12 weeks, and clascoterone was tested in 1,440 males and females.

Daily Routine Best Practices

Cleanse gently
Wash once or twice a day with a mild soap and don't scrub.
Moisturize consistently
Use non-comedogenic products; a moisturizer helps with retinoid dryness.
Sunscreen
Wear it daily: adapalene makes skin sensitive to sunlight.

If you are pregnant

Never take isotretinoin: it causes birth defects. Ask your doctor before using adapalene or benzoyl peroxide.

When to see a dermatologist

Go if pharmacy products fail after several months, or for cysts, scars or emotional stress.

Quick answers

Why is my pimple turning into a hard lump under the skin?

The clog sits deep in the skin, the body reacts, and you get a hard, painful nodule or cyst. Don't squeeze it, and see a doctor if they keep coming.

What is mistaken for cystic acne?

A boil from a staph infection can look like a big acne cyst. If a lump gets hot, swollen and red, get it checked.

What kills acne naturally?

Nothing natural matches the ranked options. Gentle washing, no picking and non-comedogenic products help; a tan only hides acne.

Is acne genetic?

Partly. Acne runs in families, and genes are one factor behind adult acne in women, next to hormones and stress.

What age is acne worst?

It is most common in the teen years and usually fades after them, but it can last into middle age or start for the first time as an adult.
