Our best-selling serum fights visible signs of fatigue for a radiant, more rested look in just 1 night. Lack of sleep, a stressful schedule, and external aggressors (e.g. harsh weather conditions, smoke, and air pollution) can prevent the skin from working efficiently and accelerate the production of free radicals. This can create oxidative stress and damage the cells, altering the look of healthy, youthful skin, causing fine lines, wrinkles, sagging, and dullness. This lightweight, refreshing formula helps you to combat these daily stressors. It melts into the skin, smoothing fine lines and revitalizing your overall look. After just 1 week, skin is soothed!
