Brand note
StriVectin is an anti-aging brand that leans on peptides and retinol, but its formulas often include fragrance, which can be a trade-off for sensitive skin. The Daily Reveal Exfoliating Pads offer a gentle acid blend (AHA, BHA, PHA) that smooths skin without stinging, best used as an occasional reset step rather than daily.
