This overnight collagen face mask is designed to support deep hydration and skin firmness. Each pack contains four individual masks formulated with bio-collagen, a ingredient known for its ability to help maintain skin elasticity and moisture retention. The mask is intended to be applied before sleep, allowing the concentrated serum to absorb gradually throughout the night without the need for rinsing.

The formula focuses on delivering a high concentration of collagen peptides, which may assist in reducing the appearance of fine lines and promoting a smoother, plumper complexion. The term "glass skin" in the product description refers to a clear, translucent, and well-hydrated skin texture often associated with consistent use of hydrating treatments. This mask is suitable for individuals looking to incorporate an intensive overnight treatment into their skincare routine, particularly those with dry, dehydrated, or mature skin.

The lightweight, gel-like texture adheres closely to the face, minimizing dripping and maximizing contact with the skin. It is free from harsh additives, making it appropriate for sensitive skin types when used as directed. The pack offers a practical quantity for regular use, whether once or twice per week, without requiring frequent repurchase. The core advantage of this product lies in its concentrated collagen content combined with an overnight delivery system, offering an efficient way to support skin repair and hydration during the body’s natural regeneration cycle at night. It is not a substitute for medical treatment but serves as a supplementary skincare step for those seeking to improve overall skin texture and suppleness.
