The most common signs of aging skin are pigment changes, drying, loss of elasticity and fine lines. As the skin ages, it dries and becomes thinner and more vulnerable towards free radicals. Thus, the main aspect of anti-aging skin care is hydration and moisturizing. The dryness of aging skin can be reduced by deeply moisturizing and nourishing the skin with essences, serums and ampoules. Make sure to lock the moisture in with a nourishing cream in the morning and sleeping mask at night. Use a sheet mask once or twice a week to help your skin maintain its elasticity.
