Power Couple Advanced Retinol and Lactic Acid Duo

A dual-action spot treatment from Sunday Riley combining retinol and lactic acid to target breakouts and uneven texture. The duo blends a potent retinol component with a complementary lactic-acid treatment for targeted use. Lightweight in feel and suitable for blemish-prone skin looking to refine tone and reduce marks, it’s designed for spot application rather than all-over nightly use.
