Using tretinoin cream on sun-damaged skin doesn’t always make it feel smoother to the touch, even after two years of use—so it might work better for reducing wrinkles or dark spots than for smoothing rough skin texture.

Topical tretinoin for treating photoaging: A systematic review of randomized controlled trials

Systematic Review

Human

2022 Mar

The study found that tretinoin cream consistently improved many signs of sun-damaged skin, including wrinkles and discoloration, over two years. The claim says it doesn’t work well for rough skin texture, but the study’s results suggest it likely does, so the claim is wrong.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Using a special cream with tretinoin (0.025% to 0.1%) every day or every other day for up to two years can noticeably reduce sun damage like wrinkles, dark spots, and dull skin — and you might start seeing results in just one month.

Using a cream with tretinoin in strengths between 0.025% and 0.1% can really help reduce sun damage on your skin, but the super weak 0.01% version doesn’t do much—plus, a strong 5% peel works just as well for looks but changes your skin’s inner structure differently.
