The Peter Thomas Roth Peptide 21 Wrinkle Resist Serum is an ultra-potent anti-aging treatment packed with a 73% complex of 21 Peptides and Neuropeptides and 2 Gamma Proteins, formulated to help skin appear noticeably younger. Designed to target every area of the face and neck for comprehensive 360° results, it visibly reduces the appearance of fine lines and wrinkles while improving skin elasticity, radiance, and uneven skin tone and texture.

The serum combines powerful cell-communicating peptides — including Acetyl Hexapeptide-8, Palmitoyl Tripeptide-5, Palmitoyl Tetrapeptide-7, and Dipeptide Diaminobutyroyl Benzylamide Diacetate — with deeply hydrating skin-identical ingredients such as Glycerin, Squalane, and Sodium Hyaluronate. Antioxidants Ascorbic Acid (Vitamin C) and Tocopheryl Acetate (Vitamin E) help defend against environmental stressors and support a brighter, more even complexion. Rosa Centifolia Flower Water adds a soothing element to the lightweight formula.

The formula is alcohol-free and free of fragrance and essential oils, making it appropriate for sensitive skin. Each bottle contains 30 mL (1 fl oz).
