SKIN TYPE: All skin types / Perricone MD Neuropeptide Instant Serum is the ultimate anti-ageing serum that harnesses the power of science to restore youthful vitality to your skin. This serum is formulated with an advanced blend of active ingredients, including Peptides, Hyaluronic Acid, Niacinamide, Glycolic Acid, and Lactic Acid. The star ingredient in this serum is Peptides. Peptides are short chains of amino acids that act as building blocks for proteins, such as collagen and elastin. As we age, the production of these proteins slows down, leading to fine lines, wrinkles, and sagging skin. Peptides work by signalling the skin to produce more collagen and elastin, resulting in a firmer, more youthful complexion. In addition to peptides, Perricone MD Neuropeptide Instant Serum contains hyaluronic acid, a powerful humectant that draws moisture to the skin, keeping it plump and hydrated. Niacinamide, also known as vitamin B3, helps to reduce the appearance of fine lines and wrinkles, while glycolic acid and lactic acid gently exfoliate the skin, revealing a brighter, smoother complexion.
