Tretinoin vs. Adapalene

See how Tretinoin and Adapalene compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Tretinoin and adapalene are both topical retinoids that treat acne vulgaris by unclogging pores and calming inflammation, but tretinoin also has an FDA approval for fine wrinkles and hyperpigmentation.

  • Adapalene tends to cause milder irritation than tretinoin, which is one reason it is a common first retinoid for teens and people with sensitive skin.

  • Tretinoin covers a wider range of approved and off-label uses, while adapalene is approved only for acne in patients 12 and older but is sold over the counter.

Tretinoin vs. Adapalene Indications

Tretinoin

Tretinoin is FDA-approved for treating acne vulgaris and, in the Renova formulation, for reducing the look of fine wrinkles, mottled hyperpigmentation, and rough skin texture from sun damage. Doctors also prescribe it off-label for general anti-aging and for melasma or other hyperpigmentation.

  • Acne vulgaris (all forms)

  • Fine wrinkles (Renova)

  • Mottled hyperpigmentation (Renova)

  • Off-label: melasma/hyperpigmentation

Adapalene

Adapalene is FDA-approved only for treating acne vulgaris in patients 12 years of age and older. It has no other approved dermatologic uses, and its milder irritation profile makes it a common starting retinoid for teens and first-time users.

  • Acne vulgaris in ages 12+

  • Available by prescription or OTC

  • Combination products with benzoyl peroxide

  • Not approved for wrinkles or pigmentation

Tretinoin vs. Adapalene Pros and Cons

Tretinoin

Tretinoin has decades of clinical use and comes in multiple strengths and formulations, giving prescribers flexibility for different skin types and concerns. It carries a higher risk of irritation than newer retinoids and is not sold over the counter.

Pros

  • Also FDA-approved for wrinkles and hyperpigmentation (Renova)

  • Available in multiple strengths and formulations

  • Generic pricing is roughly $15 to $60 per month

  • Long track record since FDA approval in 1971

Cons

  • Higher rates of burning and irritation than adapalene

  • Pregnancy Category C; must avoid during pregnancy

  • Not available over the counter

  • Not approved for use under age 12

Adapalene

Adapalene has a narrower, better-tolerated profile that makes it a common entry-level retinoid, but it lacks tretinoin's approvals for wrinkles and pigmentation. Brand and combination versions can cost significantly more than generic tretinoin.

Pros

  • Available over the counter as Differin Gel 0.1%

  • Approved for use in adolescents as young as 12

  • Sold in combination with benzoyl peroxide

  • Generally milder irritation than older retinoids

Cons
