This overnight sheet mask from Quasi is formulated with niacinamide and low molecular collagen, ingredients selected to support skin hydration and surface smoothness. The low molecular weight of the collagen is intended to enable easier absorption into the upper layers of the skin, contributing to a firmer and more even texture over time. Niacinamide, a well-studied B vitamin derivative, is included to help strengthen the skin barrier and improve the appearance of dullness and uneven tone.

Designed as a Korean-style sheet mask for overnight use, each single-use mask delivers a concentrated serum that adheres closely to the face, allowing the active ingredients to remain in contact with skin for an extended period. The mask is suitable for all skin types, including sensitive skin, and does not contain common irritants such as parabens or artificial fragrances. The formula has a lightweight, non-greasy finish that absorbs without leaving a sticky residue.

Regular application may help maintain the skin’s natural moisture balance while providing a smooth and supple feel upon waking. The product comes in a pack of four individually sealed masks, making it convenient for maintaining a consistent skincare routine at home or while traveling. This mask is particularly suited for those seeking a hydration-focused treatment with firming and smoothing benefits, without the need for rinsing. It is best applied after cleansing and before any additional creams or moisturizers. As with any skincare product, individual results may vary depending on skin condition and consistency of use. The formula is dermatologically tested and aims to support daily skin comfort and resilience.
