Tazarotene: what it treats, how to use it, side effects
Last updated September 3, 2026.
Tazarotene (brand names Tazorac, Fabior, Avage) is the most potent prescription topical retinoid, used once nightly for acne and plaque psoriasis. More powerful than over-the-counter retinols and tretinoin in head-to-head terms, and more irritating, with a hard pregnancy rule.
What does it treat?
The 0.1% cream or gel treats acne vulgaris; the 0.05% and 0.1% cream treats plaque psoriasis; the Avage version is for fine facial wrinkling and discoloration alongside sun-protection programs. Like all retinoids, it normalizes how skin cells turn over and unclogs pores, rather than killing bacteria.
How do you take it?
A thin layer on affected areas once daily in the evening, on clean, fully dry skin, kept out of the eyes, mouth, and vagina. Start with a pea-size amount and expect irritation in the first weeks; buffering over moisturizer and every-other-night starts are legitimate ramp strategies. Acne improves in about 4 weeks, psoriasis in 1 to 4 weeks, with best results taking months. The pregnancy rule is absolute: a negative pregnancy test within 2 weeks before starting, effective contraception throughout, and stop immediately if pregnancy happens.
Side effects to know
- Common: burning, stinging, redness, peeling, itching, and dryness, worst in weeks 1 to 4, plus heightened sun sensitivity.
- Serious: severe irritation requiring a pause, and fetal harm if used in pregnancy; tazarotene is a teratogen and the label contraindicates pregnancy outright.
Who should not take it?
Anyone pregnant or trying to conceive, and anyone with hypersensitivity to it. Eczematous, sunburned, or broken skin should heal first. People with unusual sun sensitivity or outdoor occupations need an honest conversation about compliance with sun protection. Other retinoids and harsh exfoliants stack irritation, not benefit. Keep expectations calibrated: the purge-and-peel phase is the price of admission.
When is it an emergency?
Call 911 for a severe allergic reaction with facial swelling or trouble breathing. Blistering, severe swelling, or eye involvement from the cream warrants same-day contact with your prescriber. A positive pregnancy test while using it means stop and call your doctor promptly.

Common questions
How is tazarotene different from tretinoin?
Both are prescription topical retinoids, but tazarotene is the more potent and selective one, and is approved for psoriasis as well as acne. With potency comes irritation: more peeling and burning in the first month. For acne unresponsive to tretinoin or for psoriasis, that extra strength is the point.
Why is the pregnancy rule so strict?
Tazarotene is a teratogen, meaning it can cause fetal harm, and the label contraindicates it in pregnancy. The protocol is concrete: a negative pregnancy test within 2 weeks of starting, effective contraception the whole time, and immediate discontinuation if pregnancy occurs. Even though skin absorption is low, the risk is not treated as theoretical.
My skin is peeling and angry after two weeks. Normal?
Normal and expected: burning, redness, and peeling peak in the first few weeks, then settle as skin adapts. The fixes are less product (a true pea-size), a slower start (every other night), and moisturizer buffering. Blistering, cracking, or pain means pause and call, not push through.
Can I use it with benzoyl peroxide or salicylic acid?
Carefully, and usually on a schedule your dermatologist sets, such as benzoyl peroxide in the morning and tazarotene at night. Layered on the same application they mostly just multiply irritation. Salicylic-acid cleansers are usually fine; leave-on acids are where restraint matters.
Does it really work for psoriasis?
Yes, it is labeled for plaque psoriasis at 0.05% and 0.1%, and it flattens plaques and reduces scaling over 1 to 4 weeks and beyond. It often pairs with a topical steroid in rotation, because steroid-sparing control is the long game in psoriasis.
Will it help wrinkles and dark spots too?
The Avage version is approved for fine facial wrinkling and discoloration within a full skincare and sun-avoidance program, and retinoids broadly are the evidence-backed topical for photoaging. It takes months, and the sun-protection part is not decorative: unprotected UV can undo the gains and add irritation.
