Tretinoin: cost, evidence, and the honest comparison
Tretinoin is vitamin A acid. It speeds cell turnover and, over months, changes how skin builds collagen — the mechanism behind both its acne and its anti-aging effects.
What it's approved for
Topical treatment of acne vulgaris; also long used for photoaged skin, where the controlled-trial evidence is decades deep.
What the research actually shows
The 1988 double-blind vehicle-controlled JAMA trial established tretinoin's effect on photoaged skin, and the evidence has compounded since. Most premium 'custom anti-aging formulas' are built around this generic molecule.

Side effects, stated plainly
Irritation, dryness, peeling, and sun sensitivity are expected early and usually settle. Retinoids are avoided in pregnancy.
What it costs
Generic tretinoin with a prescription costs a fraction of custom-formula subscriptions — and the subscriptions' real trick is billing cadence, with 'monthly' prices that bill every two months or ship every 56 days.

Common questions
Is a custom formula better than generic tretinoin?
Custom compounds add convenience and combination actives; the core evidence belongs to the tretinoin inside them. If price matters, generic plus sunscreen is the evidence-dense, cheap path — our tables show both.
