helps support the appearance of skin resilience and firmness, while plant-derived Bakuchiol provides a gentle alternative to retinol for
daily early signs of aging care.
A 5 Multi-Peptide Complex complements the formula to help improve the appearance of skin firmness and texture, while Collagen and
5-Type Hyaluronic Acid provide hydration for a plumper, smoother-looking complexion.
The formula also contains Niacinamide to help improve the appearance of uneven skin tone, along with Panthenol, Betaine, Tocopherol, and Beta-Glucan
