What it is
This mildly acidic ampoule for sensitive skin provides firmness and radiance for early aging care*. Highly concentrated moisturizing ingredients are perfect for sensitive skin. We've crafted a mildly acidic pH of 5.5, ideal for skin that retains moisture and maintains flawless beauty. It quickly hydrates and protects sensitive skin, which tends to become alkaline after cleansing. A stressful lifestyle, including exposure to UV rays and lack of sleep, can make skin more susceptible to signs of aging. Proactive care leads to smoother, firmer, and more radiant skin with continued use.
