Evidence by claim
- Smooths wrinklesModerate evidence
- Retinol
Randomized trials involving 69 participants measured changes in skin texture and appearance after retinol application. While these studies observed shifts in skin markers and visible surface lines, some testing conditions differed from typical daily use. Because these findings rely on specific lab settings, the evidence supporting these visible changes is considered moderate.
