YOUR ALL-DAY SHIELD FOR VISIBLY STRONGER, SMOOTHER SKIN.

This high-performance day serum works in sync with the skin’s natural transition into protection mode. In the early hours, skin is especially vulnerable: hydration is low, the barrier is still rebuilding, and exposure to daily stressors — including pollution, blue light, and oxidative damage — is steadily increasing. This serum provides a comprehensive defense strategy: it delivers deep hydration, reinforces the barrier, and builds resilience before visible damage occurs. Advanced actives stimulate collagen and hyaluronic acid production, calm inflammatory responses, and help inhibit melanin formation — promoting a clearer, more even-toned, and luminous complexion.

Ideal for all skin types – especially dehydrated skin exposed to urban stress, air-conditioned environments, and prolonged screen time
