What is Retin-A?

Tretinoin is a topical retinoid — the active form of vitamin A. Stronger than OTC retinol (which must be converted to retinoic acid by skin enzymes; tretinoin is already retinoic acid). Used for acne, photoaging, hyperpigmentation, fine lines.

How does Retin-A work?

Binds to retinoic acid receptors in skin cells, increases cell turnover, normalizes keratinization (reduces clogged pores), boosts collagen production, decreases melanin transfer (reduces hyperpigmentation).

Who can take Retin-A?

Most adults. Not safe in pregnancy or breastfeeding (use azelaic acid instead). Causes initial irritation; build tolerance over 4-8 weeks. Sensitive skin starts at 0.025% strength.

How is Retin-A taken?

Pea-sized amount nightly on clean dry skin. Start every other night for 2 weeks, then nightly. Layer moisturizer 15 minutes after.

How much does Retin-A cost?

Compounded tretinoin formulas via telehealth $25-50/month. Direct-from-pharmacy generic $10-30/month for 20-45g tube (lasts 2-3 months).

What side effects can Retin-A cause?

Initial 'retinization period' weeks 1-8: redness, dryness, flaking, potential breakouts. Increased sun sensitivity — always use SPF 30+ daily. Avoid eye area.

What if I miss a dose of Retin-A?

Tretinoin is applied nightly. If missed: skip and resume next night. Do not double-apply — this increases irritation without proportional benefit. Missing occasional applications doesn't undo progress; consistency over months is what produces results.

What if I overdose on Retin-A?

Topical tretinoin overdose typically presents as severe local irritation — burning, redness, peeling, and blistering — not systemic toxicity. Oral retinoid ingestion (rare unless someone swallows the cream) can cause headache, vomiting, and signs of vitamin A toxicity. Call US Poison Control at 1-800-222-1222 if a child ingests the cream or for severe local reactions; seek emergency care for systemic symptoms. Discontinue use and let skin recover for the most common 'I used too much' presentation.
