Paula's Choice Clinical 1% Retinol Treatment ingredients: is it worth it?
This is a clinically strong, high-potency retinol treatment with a sophisticated barrier-support base—and it will be too much for some skins.

READ MORE
The 1% retinol headline active, supported by a lipid-rich, silicone-heavy base and multiple signal peptides, justifies a high efficacy score for anti-aging and texture, especially given the stated pH 4.7–5.7 range that favors retinoid stability and skin compatibility. The use of a gentler vitamin C derivative (tetrahexyldecyl ascorbate) and ceramide NG provides additional antioxidant and barrier support, but these sit below the primary emollients and humectants, so they function as supportive rather than driving actives. The peptide blend and soothing extracts (licorice, oat, burdock, allantoin, dipotassium glycyrrhizate) help counter some irritation, yet they cannot fully offset the inherent aggressiveness of a true 1% retinol formula, so this remains a product best suited to experienced, well-conditioned retinoid users rather than beginners.
