A routine for oily and acne-prone skin: cleansing, OTC treatments and patience

Oily skin and acne are not the same thing, but they often travel together. Oil (sebum) is one of the four factors in acne, alongside clogged pores, bacteria and inflammation. The good news is that some of the most effective acne treatments in the world are available without prescription in the US. The bad news is that most people use them too strongly, too often, and stop too soon.

At a glance

Wash up to twice a day and after sweating, with a mild cleanser and your fingertips. Scrubbing makes acne worse.
The three main over-the-counter treatments are benzoyl peroxide, salicylic acid and adapalene 0.1%.
Keep a light, noncomedogenic moisturizer and a daily sunscreen; treatments dry the skin and some increase sun sensitivity.
Give any treatment 6 to 8 weeks before judging it.

Cleansing without stripping

The American Academy of Dermatology's advice for oily skin is about balance: control excess oil without removing all of the skin's natural moisture. Harsh, alcohol-based or gritty cleansers, and frequent washing, can irritate skin and make it feel even oilier. In practice:

Use a mild, foaming or gel cleanser, morning and evening, and after exercise or heavy sweating.
Apply it with your fingertips and rinse with lukewarm water. Skip washcloths, sponges and scrubs.
Look for "oil-free" and "noncomedogenic" on moisturizers, sunscreens and makeup.
Blotting papers can remove midday shine without disturbing makeup or sunscreen.
Don't pick, squeeze or pop. It prolongs healing and raises the risk of dark marks and scars.

The three OTC treatments

Over-the-counter acne treatments in the US
Ingredient	What it does	Typical strength	Watch out for
Benzoyl peroxide	Kills acne bacteria, helps unclog pores; reduces antibiotic resistance when used with antibiotics	2.5% to 10%; the AAD suggests starting at 2.5% to 5%	Dryness; bleaches fabric, towels and pillowcases
Salicylic acid	Oil-soluble exfoliant (BHA) that clears clogged pores	0.5% to 2% in OTC acne products	Dryness, stinging; avoid broad use on large areas
Adapalene 0.1%	Retinoid that prevents the blockages that become pimples	0.1% gel, OTC in the US since 2016 for ages 12+	Dryness, irritation in the first weeks; sun sensitivity; avoid in pregnancy

Benzoyl peroxide at 2.5% is often as effective as higher strengths, with less irritation; it is a sensible starting point. Wash-off benzoyl peroxide cleansers are another gentle way in. Adapalene is used once a day, in the evening, as a thin layer over the whole acne-prone area, not just on spots. Our guide to retinoids explains how to start it without giving up.

Dermatology guidelines, including the American Academy of Dermatology's 2024 guidelines of care for acne, recommend topical retinoids and benzoyl peroxide as core treatments, alone or in combination.

A routine that works for most people

Morning

Gentle cleanser, or a benzoyl peroxide wash, left on for a minute and rinsed.
Light moisturizer, oil-free gel or lotion. In very humid weather, some people skip it if their sunscreen is moisturizing.
Sunscreen, broad-spectrum SPF 30 or higher, in a gel or fluid texture labelled noncomedogenic.

Evening

Cleanse to remove sunscreen and sweat.
Treatment: adapalene or salicylic acid or a benzoyl peroxide leave-on. One at a time to start, ideally every other night for the first two weeks.
Moisturizer.

Supporting players

Niacinamide at 2% to 5% may help redness and oiliness and is well tolerated.
Exfoliating acids such as lactic or glycolic acid can help texture and marks, but stack irritation with retinoids. If you use one, such as the lactic acid serum we decode, alternate nights.
Hypochlorous acid mists, such as the SOS spray, are gentle and popular after workouts, but evidence for acne is limited. They are an extra, not a treatment.

Oily skin in a hot, humid climate

Heat and humidity increase sweating, and many people feel oilier in the tropics. Sweat itself doesn't cause acne, but sweat trapped under heavy creams, helmets, masks or tight clothing can trigger breakouts and a related problem, heat rash. Wash after heavy sweating, choose lighter textures, and reapply sunscreen rather than layering more of everything. Our guide to skincare in a hot, humid climate has a full routine.

Myths about oily skin

"Oily skin doesn't need moisturizer." Acne treatments dry the skin, and irritated, dehydrated skin often looks oilier. A light moisturizer usually makes treatments easier to tolerate.
"Washing more often controls oil." Over-washing irritates; the AAD's advice is up to twice a day and after sweating.
"Sun clears acne." A tan can hide redness for a while, but UV damages skin, darkens acne marks, and some treatments make skin burn more easily.
"Toothpaste dries spots." It irritates skin; use a proper spot treatment.

What to expect

The timeline

The AAD advises giving an acne treatment 6 to 8 weeks to work, and continuing once acne clears to keep it from returning. In the first weeks of a retinoid, skin may feel dry and acne may briefly look worse; that usually settles. If a product causes burning, swelling or a spreading rash, stop it.

Makeup and hair products

Makeup doesn't have to be avoided with acne, but choose products labelled oil-free or noncomedogenic, clean brushes and sponges regularly, and remove makeup every evening. Hair products that contain oils or heavy silicones can cause breakouts along the hairline and forehead; keep them off the face, and wash your face after applying them.

When to see a dermatologist

Deep, painful nodules or cysts.
Acne that leaves scars or dark marks.
No improvement after two to three months of consistent OTC treatment.
Sudden adult acne with other symptoms such as irregular periods or excess hair growth.
Acne that affects your mood or confidence. It's a medical condition, and effective prescription treatments exist.
