Tretinoin: a prescription retinoid, what the sources say

Reviewed October 17, 2026

The short answer

Tretinoin is a retinoid medicine. Healthline calls it a prescription-strength cream or gel, and WebMD says to use it only if a healthcare provider has prescribed it to you. This page only reports what those sources say. It gives no dosing, strength or schedule advice: that belongs to your prescriber.

What is it used for?

Cleveland Clinic has separate medication sheets for tretinoin cream, one for acne and one for facial wrinkles. Healthline names acne, sun damage and fine wrinkles as the main uses, and adds that deep wrinkles will not disappear.

How does it work?

Healthline explains that tretinoin irritates the skin and makes skin cells multiply and die off more quickly, letting newer cells replace them.

Irritation and sun sensitivity

• Cleveland Clinic: slight irritation, redness or dryness usually needs no medical attention, but report it if it lasts or bothers you. Treated skin that burns, itches, crusts or peels is something to report promptly.
• WebMD: skin can turn flaky, dry, red, swollen or blistered. If this worsens or lingers, stop using it and contact your provider.
• Cleveland Clinic and WebMD: sun sensitivity can go up. Both recommend sunscreen and protective clothing and say to avoid sunlamps and tanning beds.
• WebMD: applying extra, or applying it more often than instructed, gives no quicker or better result and may bring redness and peeling.
• WebMD recommends a moisturizer, since harsh cleansers, astringents and alcohol-based products can add to dryness. Cleveland Clinic also says to avoid abrasive cleaners and alcohol products.

Pregnancy and breastfeeding

Cleveland Clinic includes pregnancy, plans for pregnancy and breast-feeding on its list of things to mention to your care team before using tretinoin. Healthline says controlled studies are too few to judge safety in pregnancy, and that it is not yet known if tretinoin reaches breast milk; its advice for breastfeeding is to avoid tretinoin. If you are pregnant, planning a pregnancy or breastfeeding, ask your prescriber before using it.

Other products

Cleveland Clinic names drying products, including salicylic acid and benzoyl peroxide, as possible interactions. It also says other acne treatments should stay off the same patch of skin unless your care team wants both used. Ask your prescriber about what else to use alongside it.

What not to conclude

This page cannot tell you whether tretinoin suits you or how to use it. Nitavera is an ingredient-name checker: it cannot see a prescription, a strength or your medical history. Questions about starting, stopping or combining it go to your prescriber or pharmacist.
