Retinoids are vitamin A-based medicines that unclog pores and calm inflammation to treat acne. For 2026, they remain a first-choice option for teens, adult women, and children age 9 and older, backed by strong guideline support, with best results from a slow start plus moisturizer and sunscreen.
Acne affects about 50 million people in the United States and an estimated 85% of U.S. adolescents, with persistence into adulthood common, according to a 2025 cosmetics epidemiology review in Cosmetics. That pattern makes teens, adult women, and preadolescents age 9 and older the main retinoid-treatment population.

How do retinoids clear acne?
Retinoids normalize how skin cells shed inside the hair follicle. They loosen tiny plugs called microcomedones, help drain sebum and C. acnes, make the follicle more aerobic, and suppress inflammatory pathways.
The NIH/PMC review of tretinoin describes this as deeper pore-level action rather than simple surface exfoliation. That mechanism matters because many breakouts start as unseen microcomedones. By stopping new plugs and calming inflammation, retinoids reduce both blackheads and whiteheads and red, tender bumps over time.
Which retinoids are approved for acne?
Four topical retinoids are FDA-approved for acne: tretinoin, first approved in 1971, adapalene in 1996, tazarotene in 1997, and trifarotene 0.005% cream in October 2019, according to Dermatology Times reporting on the FDA approval. All four treat facial acne when prescribed for the right patient.
Trifarotene stands out for coverage. It is approved for face and trunk in patients 9 years and older. That makes age, face-versus-body breakouts, and skin sensitivity practical factors when a clinician chooses among the four.
What does the evidence show?
The American Academy of Dermatology's 2024 acne guidelines give a strong recommendation, based on moderate-certainty evidence, for topical retinoids alone or in fixed-dose combinations with benzoyl peroxide and/or antibiotics, as reported in American Academy of Dermatology guidance via Newswise. Combination use is now the expected path for many patients.
Systematic reviews find topical retinoids reduce visible inflammatory and non-inflammatory lesions and inhibit new microcomedone formation. The Pharmaceutics systematic review via NIH/PMC highlights trifarotene's PERFECT 1 and 2 trials, with facial lesion reduction as early as week 1 and the only retinoid with demonstrated truncal-acne efficacy. A separate NIH/PMC systematic review from May 2024 found retinoids most improved overall severity and non-inflammatory lesions, while topical antibiotics mainly reduced inflammatory lesions, supporting combinations to broaden effect and limit antibiotic resistance.
How can you start without quitting early?
All topical retinoids commonly cause dryness, redness, peeling, stinging, and an early treatment flare. UNC Health dermatology experts advise a low-and-slow routine to build tolerance: start 2–3 nights weekly, use only a pea-sized amount on dry skin, buffer with moisturizer, and wear daily SPF 30, as explained in their dermatologist retinoid FAQ. A simple starting routine looks like this:.
- Apply a pea-sized amount to clean, fully dry skin 2–3 nights per week
- Moisturize before, after, or both to buffer irritation
- Use broad-spectrum SPF 30 every morning and reapply for long sun exposure
- Increase nights gradually only if peeling and stinging stay mild
Who should avoid retinoids?
Oral isotretinoin carries an FDA boxed warning for severe birth defects with mandatory iPLEDGE restricted distribution. Topical retinoids are also generally avoided in pregnancy, according to the FDA isotretinoin REMS Prescriber Guide from 2021.
Anyone who is pregnant or may become pregnant should seek non-retinoid alternatives. Bring a current medication list, pregnancy plans, and breastfeeding status to the dermatology visit so the clinician can select a safer acne plan.
