Serum to prevent the appearance of signs of aging. Preventing the passage of time on our skin is a pleasure with this vegan serum from Klairs. It does this with the help of the peptides EGF and FGF, which are produced naturally in the skin, but are damaged by the passage of time and free radicals. This concentrated serum repairs them, thus stimulating the recovery of epidermal cells and the production of collagen and elastin. We like how well our skin does when it is more reactive and delicate and we love its indigo blue color that makes it special and sophisticated. Artificial dyes? No, Klairs does not use synthetic fragrances or dyes. The explanation lies in one of the natural ingredients it contains called guaiazulene. It comes from chamomile; hence that bluish tone. It is super light but powerful: You can use it even if you have very oily skin. How to use: With the help of the dropper, pour between 4 and 5 drops of the serum on the main points of the face: cheeks, forehead and chin. Massage the product well with your fingers until it is absorbed.
