The three main over-the-counter options

Details are from each product's Drug Facts label on DailyMed. Benzoyl peroxide and salicylic acid labels both list the purpose as acne treatment or acne medication. The adapalene label calls it a retinoid.

Benzoyl peroxide spot treatments

Neutrogena's On-the-Spot label lists benzoyl peroxide 2.5% as the active ingredient, for the treatment of acne. Its directions: clean the skin thoroughly, cover the entire affected area with a thin layer one to three times daily, and start with one application daily because excessive drying may occur. If bothersome dryness or peeling occurs, reduce to once a day or every other day.

Watch for two practical issues on the label. Benzoyl peroxide may bleach hair or dyed fabrics, so keep it away from your hairline, colored towels and pillowcases. And skin irritation may occur, characterized by redness, burning, itching, peeling or possibly swelling; the label says irritation may be reduced by using the product less often or in a lower concentration. Do not use it if you have very sensitive skin or are sensitive to benzoyl peroxide.

Salicylic acid spot treatments

Philosophy's Clear Days Ahead label lists salicylic acid 2.0% for the treatment of acne. Its directions match the benzoyl peroxide pattern: cleanse skin thoroughly, cover the entire affected area with a thin layer 1-3 times daily, start with 1 application daily and increase gradually if needed, and cut back to once a day or every other day if bothersome dryness or peeling occurs.

The label advises asking a doctor or pharmacist before use if you are using other topical acne medications at the same time, because that may increase dryness or irritation. If redness or irritation persists, contact your doctor.

Adapalene: not a spot treatment

Adapalene 0.1% gel, sold as Differin Gel and as other brands, is an over-the-counter retinoid. Its label says to cover the entire affected area with a thin layer, for example the entire face if your acne is on the face, once daily and no more. Applying more than directed will not provide faster or better results, but may worsen skin irritation.

• Expect a slow start. During the early weeks, acne may appear to worsen before it improves, which the label calls normal.
• Give it time. It may take up to 3 months of once daily use to see results; ask a doctor if you see no improvement after 3 months.
• Sun and waxing. Limit sun exposure, including tanning beds, use sunscreen outdoors, and do not wax treated areas.
• Pregnancy. If pregnant or breast-feeding, ask a doctor before use, and stop and ask a doctor if you become pregnant or plan to.
• Age. For adults and children 12 years and older; ask a doctor for children under 12.

Using spot treatments without overdoing it

• One at a time. The benzoyl peroxide label says irritation and dryness are more likely if you use another topical acne medication at the same time; if irritation occurs, use only one at a time.
• Clean first. Every label says to clean the skin before applying. See our facial cleanser guide for gentle options.
• Sunscreen. The benzoyl peroxide label says to avoid unnecessary sun exposure and use a sunscreen; see our mineral sunscreen guide.
• Avoid eyes, lips and mouth. All three labels warn against contact with the eyes.
• Covering a spot. For a pimple you want to protect from picking, see our acne patches guide.

When to see a doctor

The labels say to stop use and ask a doctor if irritation becomes severe. The adapalene label adds signs of an allergic reaction to watch for, such as itching, rash, hives, swelling of the lips or eyelids, and shortness of breath; get help right away for those. Keep all acne medications out of reach of children, and contact Poison Control if one is swallowed.

See a doctor or dermatologist if over-the-counter products are not helping, if acne is deep and painful, or if it is leaving scars or dark marks. Prescription treatments are available.
