Estée Lauder'sAdvanced Night Repair Rescue Solution Serum With 15% Bifidus Ferment features a sensitive skin formula that powerfully reduces the look of redness and irritation now and helps prevent it in the future. 0.68 oz. Made in USA. WHAT IT DOES This sensitive skin formula, powered by 15% Bifidus Ferment, works as a powerful daily rescue for irritated, redness-prone, or visibly sensitized skin: The rapidly absorbing, fluid serum texture is ideal for fragile, vulnerable skin. The formula reduces the look of ongoing redness and red post-acne marks—as well as visible irritation caused by cosmetic procedures such as a 50% glycolic acid peel, and external triggers including everyday face shaving for men. Leaves skin feeling calm, hydrated and supple. Looking brighter and more radiant. HOW TO USE IT Apply AM and PM before serum. Ideal for layering under Advanced Night Repair.
