What happens to skin overnight?

Skin is biologically different from day to night. Every night, your skin repairs damage and re-energizes, while its natural collagen production peaks. It is also more prone to moisture loss and has a thinner, more fragile barrier. That’s why we recommend having a dedicated nighttime routine, made with ingredients that can deliver powerful renewing benefits overnight.
