111SKIN Celestial Black Diamond Lifting and Firming Treatment Mask is a high-performance sheet mask designed to support the skin’s natural remodeling process. Each mask in this set of five is saturated with 2.5 ounces of a concentrated serum that incorporates fine black diamond particles, which are intended to aid micro-circulation and create a gentle warming sensation that may help active ingredients penetrate more effectively. The formula is built around a blend of peptides, vitamin C derivatives, and hyaluronic acid, targeting multiple signs of aging such as loss of firmness, uneven tone, and surface texture irregularities. By promoting hydration and supporting collagen synthesis, the mask aims to refine the skin’s appearance without the addition of fragrance or common irritants. This fragrance-free formulation is suitable for a variety of skin types, including those with reactive or sensitive complexions. The dense, biocellulose‐derived sheet adheres closely to the contours of the face, allowing the serum to deliver sustained moisture and nutrients over the recommended 20–30 minute application. Regular use—consistent with a weekly or twice‐weekly routine—may contribute to a more lifted, toned, and resurfaced complexion. The product is positioned for individuals seeking a targeted, professional‐grade at‐home treatment that focuses on structural improvement rather than quick surface effects. It does not claim instant or permanent results, but instead offers a science‐driven approach to gradual skin renewal. Each individually sealed mask preserves freshness and maintains the potency of the active ingredients until first use. This set provides enough material for multiple treatments, making it a practical option for those who wish to incorporate a high‐intensity masking step into their existing skincare regimen.
