In this formula, marine collagen is used primarily for its film-forming effect. This means it can create a subtle, temporary layer on the skin's surface that helps to soften its appearance and impart a fresher, more even look while the mask is on and immediately after use. It works alongside other ingredients like hyaluronic acid, which attracts water, to give the skin a smoother, more replenished appearance. The sheep placenta proteins are included as a conditioning agent, a common feature in intensive Asian beauty masks aimed at improving the skin's feel of elasticity and overall condition. It's important to understand that these ingredients function as cosmetic actives—they are not intended to penetrate and rebuild your skin's structural proteins. Their role is to provide intensive surface conditioning and improve the sensory experience of the treatment, which is why the product may be chosen for periods when skin feels tired or stressed. The inclusion of vitamins C and E complements this by providing antioxidant support.
