Tretinoin vs. Differin
See how Tretinoin and Differin compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Tretinoin and Differin are both topical retinoids for acne, but tretinoin is also FDA-approved for fine wrinkles and hyperpigmentation, while Differin's approval covers acne only.
Tretinoin causes more skin irritation, with burning reported in up to 8% of users, while Differin's side effects are generally reported at rates just above 1%.
Differin is available over the counter at 0.1% strength, while tretinoin always requires a prescription.
Tretinoin vs. Differin Drug Summary
Tretinoin
Tretinoin is a topical retinoid, a vitamin A derivative, that treats acne vulgaris and is also FDA-approved to reduce fine wrinkles and mottled hyperpigmentation under the Renova brand. It works by speeding up skin cell turnover and is applied as a thin layer once daily, usually at night. It was the first topical retinoid the FDA approved, back in 1971.
Differin
Differin (adapalene) is a topical retinoid used to treat acne vulgaris in patients 12 and older. It normalizes skin cell turnover to unclog pores and reduce breakouts, applied as a thin film once daily in the evening. It is sold both over the counter at 0.1% strength and by prescription at a stronger 0.3% strength.

Tretinoin vs. Differin Indications
Tretinoin
Tretinoin is FDA-approved for treating acne vulgaris and, in its Renova formulation, for smoothing fine wrinkles and evening out mottled hyperpigmentation from sun damage. Doctors also prescribe it off-label for general anti-aging use and melasma, though those uses fall outside its official labeling.
Treats acne vulgaris
Reduces fine wrinkles and hyperpigmentation (Renova)
Off-label for photoaging and melasma
Available in cream, gel, and microsphere gel forms
Differin
Differin is FDA-approved solely for treating acne vulgaris in people age 12 and older. It is not indicated for wrinkles, pigmentation, or other skin conditions, keeping its labeling narrower than tretinoin's.
Treats acne vulgaris
Approved for ages 12 and up
Available in gel, cream, and lotion
Sold both over the counter and by prescription
Tretinoin vs. Differin Pros and Cons
Tretinoin
Tretinoin has decades of clinical use and the broadest FDA labeling of any topical retinoid, covering both acne and visible signs of photoaging. It tends to cause more irritation than adapalene, especially early in treatment, and always requires a prescription.
Pros
Also FDA-approved for fine wrinkles and hyperpigmentation (Renova)
Available in multiple strengths and formulations, including cream and gel
Longest track record of any topical retinoid, approved since 1971
Cons
Higher rates of burning and irritation than Differin (up to 8%)
Not approved for children under 12 in the gel microsphere form
Pregnancy Category C with an explicit fetal risk warning
Differin
Differin offers a gentler side effect profile and the convenience of an over-the-counter option, making it an easier starting point for many people. Its FDA approval is limited to acne, so it lacks the anti-aging indication that tretinoin carries.
Pros
Available over the counter at 0.1% strength, no prescription needed
Lower reported irritation rates, with common effects just above 1%
No boxed warning on the label
Cons
Only approved for acne, not for wrinkles or pigmentation
Carries a specific warning about hypersensitivity and anaphylaxis risk
Fewer strength and formulation options than tretinoin
