PRESERVING COLLAGEN FOR PLUMPER, FULLER SKINDermalogica’s new Pro-Collagen Banking Serum is packed with amino acids – the building blocks of collagen – this formula gets key ingredients where your skin needs them, and goes beyond plumping to help preserve the collagen your skin has now. The result: more resilient, visibly plumper, and more luminous skin, along with a reduction in the appearance of fine lines and wrinkles into the future.
