Function
Cosmetic grade nicotinamide is a common ingredient in skin care products, usually controlled in the use of 2%~5%, its texture is moist, clean the skin, can be directly applied to cosmetic grade nicotinamide products, mainly can play an effective role in improving the skin.
As an important ingredient added to cosmetics, cosmetic grade nicotinamide has the right acids and alkalinity, and a number of skin improvement effects.
Cosmetics level nicotinamide whitening effect: between cells in the formation of melanin cells and keratin, cosmetic grade nicotinamide can inhibit melanin body transfer effect, thus inhibiting serine protease activated receptor activation, which can make the melanin corpuscle could not be transmitted, thereby inhibiting melanin precipitation, the effect of whitening skin.
Cosmetics level anti-aging effect of nicotinamide: for neurons that oxidant induced autophagy is damaged, cosmetic grade nicotinamide can not only protect, but also in cell oxidative stress response inhibition effect, prevent the membrane phosphatidylserine appear damage, reverse the early stage of the oxidative stress in the sustainability of apoptosis damage, so as to play the role of anti-aging.
Cosmetic grade nicotinamide repair effect: it can effectively promote the protein synthesis of skin epidermis and dermis microcirculation, so as to achieve the purpose of enhancing and repairing the skin barrier function, but also reduce the damage caused by free radicals.

Cosmetic grade nicotinamide improves skin barrier function:topical nicotinamide can improve the levels of free fatty acids and ceramides in the skin, stimulate the dermis microcirculation, and prevent skin moisture loss. It also enhances protein synthesis (e.g., keratin), increases intracellular NADPH levels, and speeds up the differentiation of keratin cells. It also relieves skin irritation caused by surfactants or solvents.
