111SKIN Black Diamond Contour Firming Mask is an overnight face mask formulated to support skin hydration and texture refinement during sleep. The 2.54 fl oz product contains hyaluronic acid, a humectant known for attracting moisture to the skin, and diamond peptides, which are included to assist in reducing the appearance of fine lines and wrinkles over time. This non-greasy mask is designed for all skin types, making it suitable for both dry and oily complexions without causing congestion.

The formula relies on a blend of ingredients that aim to enhance skin firmness and elasticity. Hyaluronic acid helps maintain moisture levels, promoting a plumped and smooth surface, while diamond peptides work to support collagen activity, potentially softening the look of expression lines. The mask is intended for nighttime use, allowing it to work with the skin’s natural repair processes. Its lightweight texture absorbs into the skin without leaving a heavy residue, which may benefit those who prefer a comfortable overnight treatment.

This product is positioned as a targeted solution for individuals seeking to address signs of aging, such as loss of firmness and visible wrinkles. The inclusion of diamond peptides adds a unique element to the formula, though results vary based on skin condition and consistent application. The mask is free from harsh additives, focusing instead on gentle yet effective components that align with a neutral skincare routine. For best outcomes, apply a thin layer to clean skin before bed, allowing it to work overnight, and rinse in the morning. This product does not claim immediate or dramatic changes but offers a gradual approach to improving skin texture and hydration over sustained use.
