It protects the skin against free radicals, particles with high energy potential that damage collagen, a natural skin element. As a result, there is an aging and visible appearance. Serum, on the other hand, helps stimulate the synthesis of elastin and collagen which promotes the firming of the skin, disables smaller wrinkles and supports a youthful appearance. The serum penetrates directly into the epidermis and delivers a brilliant look to the skin, compares its color tone and leaves it supple and hydrated.
