Tretinoin (Generic Retin-A)
genericFDA-approved for acne and photoaging (fine wrinkles, mottled skin, roughness)
Est. Cost
$20 - $90 per tube (1-3 month supply)
/month
Tretinoin is a prescription-strength retinoid and the active form of vitamin A. Unlike over-the-counter retinol, tretinoin does not need to be converted by the skin to be effective — it works directly on skin cell receptors to accelerate cell turnover, boost collagen production, and improve skin texture. It has been used for decades as a treatment for both acne and the visible signs of photoaging, including fine lines, rough texture, and mottled pigmentation.
Dosage Format
Applied once daily in the evening to clean, dry skin. Available in 0.025%, 0.05%, and 0.1% strengths. Most providers suggest starting at the lowest concentration and gradually increasing as tolerated.
Type
Generic
Best For
Adults looking for the most well-studied prescription retinoid for fine lines, uneven skin tone, and texture improvement
Key Benefit
Tretinoin is the only topical retinoid with decades of published clinical data supporting its use for photoaging, and it remains the gold standard in prescription anti-aging skincare.

How Tretinoin (Generic Retin-A) Works
Tretinoin binds to retinoic acid receptors in skin cells, influencing gene expression to speed up cell turnover and stimulate collagen synthesis. By encouraging faster shedding of old, damaged skin cells and promoting the growth of new ones, tretinoin may help reduce the appearance of fine wrinkles, smooth rough texture, and even out pigmentation over time. These changes typically develop gradually over weeks to months of consistent use. The initial adjustment period often involves dryness, flaking, and mild irritation — sometimes called the 'retinoid purge' — which generally subsides as the skin adapts.
Side Effects
Common
- • Dryness and peeling, especially in the first few weeks
- • Mild redness and irritation
- • Increased sun sensitivity
- • Temporary worsening of acne (purging) in some users
- • Slight stinging or burning on application
Serious (Rare)
- • Severe allergic reaction (rash, swelling, difficulty breathing) — seek emergency care
- • Excessive or persistent irritation, blistering, or crusting — discontinue and contact your provider
- • Should not be used during pregnancy or breastfeeding — tretinoin is a known teratogen
Who Is Eligible
Tretinoin is generally prescribed to adults who want to address acne, fine lines, photoaging, or uneven skin tone. It is not recommended for people who are pregnant, planning to become pregnant, or breastfeeding. Those with eczema, rosacea, or very sensitive skin should discuss with their provider before starting tretinoin, as it may exacerbate irritation. Concurrent use of other strong exfoliants may need to be paused.
