GOODNIGHT HAND MASK provides noticeably smoother hands overnight. The rich formula nourishes dry and stressed skin with a moisturizing and soothing combination of glycerin, urea, and bisabolol. Even the skin around the fingernails is intensely nourished. It supports the regeneration of cracked cuticles and prevents repeat tearing. In addition, the biotin contained in the formula strengthens the nail’s structure and increases its resistance. Dry, brittle nails once again become firm, elastic and shiny.
