What side effects can topical acne medicines cause?

Dryness, redness, peeling, and mild stinging can happen with topical acne medicines, especially retinoids such as tretinoin. Irritation may be more noticeable when treatment starts or when several drying products are used together. Not every reaction is an expected adjustment, and painful or severe symptoms should not be ignored.

Tell your physician if your skin becomes very tender, cracked, crusted, or persistently irritated. They may recommend a change in your routine, application schedule, or treatment. Avoid applying more than prescribed. Do not layer on scrubs, alcohol-based toners, or strong exfoliants without checking first. Gentle cleansing, moisturizer, and sun protection are important while using these medicines.

Stop using the product and seek urgent medical help if you have trouble breathing, widespread hives, or swelling of the lips, tongue, or face. Side effects can also depend on any added ingredients in a combination prescription. Read the pharmacy information, and ask your physician or pharmacist which warning signs apply to your exact formula.
