PROLIPHIL-C3 is a multi-functional peptide-Vitamin C derivant with skin whitening and collagen synthesis efficacy. Vitamin C has remarkable antioxidant and skin whitening activity, but it is easily decomposed by light or heat. It also has a difficulty with penetrating the skin due to its hydrophilic structure. CELLINBIO succeeded in developing PROLIPHIL-C3, a new material to overcome limitations with stability and penetration into the skin by combining unstable Vitamin C with skin-penetrating collagen peptide. Stabilized in PROLIPHIL-C3, Vitamin C penetrates the skin evenly, protects it from oxidizing damage, and controls melanin synthesis to contribute to skin whitening and wrinkle improvement.
