It's Skin Power 10 Formula LI Effector is a soothing facial serum for sensitive skin. Like a firefighter for sensitive and reactive skin, Power 10 Formula LI Effector Firefighter intervenes when skin becomes red, hot, and irritated. With extracts of licorice, chamomile, guaiazulene, and damask rose oil, this serum offers immediate, soothing, and refreshing relief. Furthermore, thanks to the presence of polyglutamic acid, hyaluronic acid, and beta-glucan, it helps maintain skin's elasticity and health, while its pro-aging action helps combat the signs of aging.
