About Vitamin C:                 1. What is it made of: Take the product 0.2g, weigh it accurately, add fresh boiled cold water 100mL and dilute acetic acid solution 10mL to dissolve, add starch indicator solution 1mL, immediately titrate with iodine titration solution (0.05mol/L), until the solution is blue and does not fade within 30 seconds, and the titration results are corrected by blank test. The volume of iodine titration solution consumed (mL) was recorded, which was equivalent to C6H8O6 of 8.806 mg per mL of iodine titration solution (0.05mol/L).	              2.The purpose of the products : Vitamin C is essential for antibody and collagen formation, tissue repair (including some redox effects), metabolism of phenylalanine, tyrosine and folic acid, utilization of iron and carbohydrate, synthesis of fat and protein, maintenance of immune function, hydroxylation and hydroxytryptamine, maintenance of blood vessel integrity, and promotion of non-heme iron absorption. Vitamin C also has antioxidant and anti-oxidant properties. Free radicals, inhibit the formation of tyrosinase, thereby achieving whitening, light spot effect.Vitamin C is a potent antioxidant used to reduce oxidative stress in ascorbate peroxidase (ascorbate peroxidase) substrates. Vitamin C is also involved in many important biosynthetic processes.                     3.Its chemical formula: C6H8O6

About vitamin b3:                1.	What is it made of: Beta-methylpyridine is oxidized to nicotinic acid by air. The latter reacts with ammonium hydroxide and is prepared by heating and dehydration.Then put nicotinic acid, boric acid and ammonia water into the reaction pot, stir them into ammonia gas and dissolve them at elevated temperature; then distill and recover ammonia, transfer it to the dehydration pot to concentrate after 120-C; when the temperature reaches 145 C, add liquid ammonia, and continue to react with ammonia at 185-190 C for 20-30 hours. Then cooling to 130 C, diluting with distilled water, adding activated carbon, and decolorizing with ammonia at 70-80~C for 2 hours. After the reaction, the filtrate is filtered while hot, and the filtrate is cooled out in water for 24 hours. The product is separated and crystallized, washed and dried with ethanol, with a yield of 89%.It is obtained by salt formation of nicotinic acid and ammonia water and then dehydration.                     2.	The purpose of the product :As your age, your skin becomes yellow and dull. External nicotinamide can improve this yellowness.It can also repair damaged cuticle lipid barrier and improve skin resistance.       3.	Its chemical formula:C6H6N2O
