Abstract
Vitamin C is known as L- ascorbic acid and is Water-Soluble Vitamin since it was observed as the factor needed for the treatment of scurvy. Vitamin C is very popular among the general population mainly due to its antioxidant properties. The human body was suggested to contain about 1.5g of vitamin C which corresponds to around 20mg/kg. In pregnant woman, an additional 5-10mg is recommended.
Sources of Vitamin C are Natural source and Synthetic source. Skin disorders include, Skin
sagging caused by natural aging and oxidative stress. Wrinkle formation caused by UV
exposure, smoking and medical treatments. Sunburn and hyper pigmentation caused by UV
exposure.
Vitamin C , it helps to improve collagen production and immune function. It also acts as
antioxidant that protects cells from damage caused by free radicals. It improves elasticity of
skin. Types of cosmeceuticals are Lotions, Sunscreen, Moisturizer, Toner, and Serum.
Vitamin C concentration is determined using 2,6 dichlorophenol indophenol (DCPIP) by using Iodometric titration method.
