HanSkincare Liposomal Vitamin C 20% serum, formulated with Pure Vitamin C, boosts collagen production, providing anti-oxidant protection and exfoliating skin to reveal healthier-look. Pure Vitamin C can penetrate faster and deeper into the dermal layer with liposomal protection as effective vehicles. 1. Vitamin C as antioxidant: Vitamin C, the most plentiful antioxidant in human skin. Vitamin C protects the skin from oxidative stress by sequentially donating electrons to neutralize the free radicals. 2. Vitamin C and photoprotection: the exposure of skin to UV light generates ROS. These radicals have a potential to start chain or cascade reactions that damage the cells. It is important to note that Vitamin C is equally effective against both UVB and UVA. 3. Collagen Synthesis: Vitamin C is essential for collagen biosynthesis. Clinical studies have shown that the topical use of Vitamin C increases collagen production in young as well as aged human skin. 4. Depigmenting agent: Vitamin C is a powerful depigmenting agent that are not toxic to the melanocyte. It works by interrupting the key steps of melanogenesis. 5. Anti-inflammatory action: Vitamin C has a potential anti-inflammatory activity and can be used in conditions like acne vulgaris and rosacea. It can promote wound healing and prevent post-inflammatory hyperpigmentation. Vitamin C (Ascorbic Acid) is unstable and, on exposure to light, gets oxidized, which imparts a yellow color. The stability of Vitamin C is controlled by maintaining a pH of less than 3.5. From a clinical point of view, it is important to note that the efficacy of the Vitamin C serum is proportional to the concentration, but only up to 20%. A persistent reservoir of Vitamin C is important for adequate photoprotection, and can be achieved by regular 8-hourly applications. As UV light lowers tissue Vitamin C levels, topical Vitamin C is best used after exposure to UV light and not prior.
