Vitamin C 500mg ascorbic acid

Vitamin C 500mg, a water-soluble vitamin, is essential for the formation of collagen which is the connective tissue of our skin, bone, ligament, tendons, joint and organ support.
 
For skin whitening and brightening, it is recommended to have IV infusions twice to three times a week over one to three months in order to obtain a full benefit (depending on the degree of skin whitening/brightening desired). Thereafter, one session every fortnight or month may be all that is needed to maintain results.
Vital roles played by vitamin C are:
Reduction of the harmful effects caused by free radicals
Regulation of collagen production
Decreasing sunburn caused by Ultraviolet B radiation exposure 
Hydrate and rejuvenate the skin
 
Vitamin C supplementation may cause side effects such as diarrhea, indigestion, and nausea.
