Corneopeptyl™ is a new patented peptide biomimetic to the LCE6A protein, obtained by green chemistry-based synthesis. By mimicking the LCE6A protein activity, Corneopeptyl™ strengthens the corneocyte envelope, enhancing the epidermal barrier for improved skin barrier function. Rebuilding skin barrier consequently future-proofs the skin by reducing the appearance of aging signs like wrinkles and fine lines and by improving skin tonicity, smoothness, and hydration.
