SkinCeuticals C E Ferulic
15% vitamin C + vitamin E + ferulic acid triple antioxidant serum
이 치료에 대해
SkinCeuticals C E Ferulic combines 15% L-ascorbic acid, 1% α-tocopherol, and ferulic acid — the world's most researched antioxidant serum.
Based on Dr. Sheldon Pinnell's patented research at Duke University, optimized at pH 2.5-3.5 for maximum L-ascorbic acid absorption. Ferulic acid doubles UV protection to 8-fold photoprotection.
Defends against UV, pollution, and blue light free radical damage while promoting collagen synthesis.
작용 기전
L-ascorbic acid (pH 2.5-3.5) penetrates stratum corneum in non-ionized form, serves as P4H cofactor for collagen triple helix stabilization. α-tocopherol terminates lipid peroxidation chain reactions. Ferulic acid regenerates oxidized C/E, extending antioxidant duration. Synergistic triple complex suppresses UV-induced thymine dimer formation and p53 overexpression.
