Acne is one of the most common skin conditions in the world, and the pharmacy aisle for it is overwhelming. Most mild acne can be treated with over-the-counter products, if you choose the right active ingredient, use it consistently and give it enough time. This guide explains what the main options do and when it is time to get professional help.
Types of acne
Acne starts when pores become clogged with oil and dead skin cells, often with bacteria and inflammation involved. Lesions range from blackheads and whiteheads (non-inflammatory) to red pimples and pustules (inflammatory) and, in severe cases, deep nodules and cysts that can scar. Mild acne is usually blackheads, whiteheads and a few pimples. Moderate to severe acne involves many inflamed lesions or any nodules and cysts.
Over-the-counter ingredients
The American Academy of Dermatology (AAD) highlights three main non-prescription options:
- Benzoyl peroxide reduces the bacteria that contribute to acne. It works best alongside another treatment and comes as washes, gels, creams and bars. It can bleach fabrics and cause dryness or irritation, so start with a lower strength.
- Salicylic acid helps open clogged pores and exfoliates the skin. It is effective for whiteheads and pimples.
- Adapalene is a retinoid available without a prescription in some countries. It clears pores and treats blackheads, whiteheads and some pimples, and can help fade dark spots left after acne clears. It can cause dryness and peeling at first.
Other ingredients you may see include azelaic acid and sulfur products. Which ones are available over the counter varies by country, so ask your pharmacist what suits you.
A simple routine
- Morning: wash gently with a mild cleanser, apply a non-comedogenic moisturizer, and finish with a broad-spectrum sunscreen of SPF 30 or higher. The AAD recommends a non-comedogenic, water-resistant option. See our sunscreen guide.
- Evening: cleanse, then apply your treatment, such as adapalene or benzoyl peroxide. Retinoids are often applied in the evening.
- Introduce one product at a time, a few days apart, so you can tell what causes irritation.
- Use as directed. The AAD points out that applying more does not clear acne faster and can cause irritation.
- If a retinoid irritates your skin, use a smaller amount, apply it less often, or apply moisturizer first, and ask a pharmacist or dermatologist for advice.
Habits to avoid: picking or squeezing lesions (which can cause scarring), scrubbing hard, over-washing, and using several strong actives at the same time.
How long to wait
Acne treatments are not instant. The AAD says to expect at least 6 to 8 weeks before you see fewer breakouts, and to stick to the plan during that time. Some people notice mild worsening or purging early on with retinoids. If there is no improvement after about 6 to 8 weeks of consistent use, or if skin is very irritated, it is time to ask for advice.
Prescription treatments
If over-the-counter products are not enough, a doctor or dermatologist can prescribe stronger options, which the AAD lists as including:
- Topical retinoids such as tretinoin, tazarotene and trifarotene.
- Topical antibiotics, usually combined with benzoyl peroxide or a retinoid to reduce antibiotic resistance.
- Combination products that contain more than one active ingredient.
- Clascoterone, a topical anti-androgen approved in some countries for people aged 12 and older.
- Oral antibiotics such as doxycycline, usually for a limited number of months and alongside topical treatment.
- Hormonal treatments, such as certain combined contraceptive pills or spironolactone, for some women with hormonal acne.
- Isotretinoin, for severe nodular acne that has not responded to other treatments. It is very effective but can cause severe birth defects, so strict pregnancy-prevention and monitoring programs apply.
- In-office procedures, including corticosteroid injections, chemical peels, light therapy and extraction.
When to see a dermatologist
The AAD suggests seeing a board-certified dermatologist if you keep breaking out despite treatment. Seek advice sooner if you have:
- Deep, painful nodules or cysts.
- Scarring or dark marks that are not fading.
- Acne that affects your mood or self-esteem.
- Sudden severe acne in adulthood, or acne with other symptoms such as irregular periods or excess hair growth.
- Uncertainty about whether it is acne, since conditions such as perioral dermatitis, folliculitis and hidradenitis suppurativa can look similar.
- Benzoyl peroxide, salicylic acid and adapalene are the main non-prescription options.
- Expect 6 to 8 weeks before judging results, and be consistent.
- Introduce products one at a time and moisturize to limit irritation.
- Do not pick or over-scrub; use sunscreen daily.
- Deep cysts, scarring or distress deserve prompt dermatology care.
Frequently asked questions
Does diet cause acne?
Evidence suggests diet may play a role for some people, with high-glycemic foods and some dairy products most often discussed, but it is not the main cause for most. If you notice a pattern, discuss it with your doctor rather than cutting out whole food groups.
Can I use these products if I am pregnant?
Some acne treatments are not recommended in pregnancy, including oral isotretinoin and often topical retinoids. Always check with a doctor or pharmacist before using any acne product while pregnant or trying to conceive.
Why is my skin getting drier or redder?
Benzoyl peroxide and retinoids commonly cause dryness and irritation at first. Use a moisturizer, reduce frequency and ask for advice if it is severe.
Does toothpaste work on pimples?
No. It can irritate the skin and is not an acne treatment.
