This innovative multifunctional day serum provides all-in-one protection and rejuvenation, shielding skin from environmental stressors, UV damage, free radicals, pollution, and blue light. It deeply hydrates, strengthens the skin barrier and promotes long-term skin health. The serum activates the formation of new collagen and hyaluronic acid production, helping to reduce wrinkles and improve elasticity for a smoother, firmer complexion. It also actively inhibits melanin production to prevent new pigmentation while diminishing existing dark spots for a more even and radiant complexion.

Ideal for all skin types, especially recommended for dehydrated, dry, or stressed skin, as well as for those who spend long hours at computers or in air-conditioned environments.
