Redefining what retinol can do for blemish-prone skin, the Sunday Riley A.I. Smart Retinoid Serum (30ml) improves the appearance of texture while defending against breakouts. Joining two types of retinoids, hydroxypinacolone retinoate (HPR) and adapinoid, this gentle yet effective formula visibly refines and refreshes even the most sensitive skin. A blend of adaptogens and peptides team up to soothe and smooth, while holy basil reduces the appearance of redness and post-blemish marks. Fast absorbing, apply before bed for radiant skin come morning.
