Melatonin is a hormone produced in the brain by the pineal gland from the amino acid tryptophan. The synthesis and release of melatonin are stimulated by darkness and suppressed by light, suggesting the involvement of melatonin in circadian rhythm and regulation of diverse body functions. Levels of melatonin in the blood are highest prior to bedtime. Synthetic melatonin supplements have been used for a variety of medical conditions, most notably for disorders related to sleep.
Melatonin possesses antioxidant activity, and many of its proposed therapeutic or preventive uses are based on this property. New drugs that block the effects of melatonin are in development, such as BMS-214778 or luzindole, and may have uses in various disorders. Function: Improve sleep; Anti-aging; Adjust immunity function; Anti-cancer etc.

HA is a natural biotic component, widely existing in skin and any other tissue. It has outstanding moisture keeping ability, thus called Natural Moisturing Factor (NMF) in the world. It is the best component used in cosmetics for moisture keeping in the nature.
When HA applied to the skin, macromolecular HA can form an air permeable thin layer and keep the skin smooth and moist, and protect the skin from bacteria, dust, and ultraviolet ray. With low molecular HA penetrating into corium, it will slightly enlarge blood capillaries, speed circulation of blood, improve intermediary metabolism and nourishment absorbing ability of skin, thus eliminating wrinkles, increasing skin's elasticity and delaying its aging. HA as well can further hyperplasia of epidermis cell, clean oxygen free radical, prevent and rehabilitate breach of skin. Its aqueous solution has very high viscosity which can make water become thicker. Creams made by means of emulsifying HA with oil is fine and homogeneous with stable emulsifiction.
HA is the best natural moisturizing component used in cosmetics. It has a good Compatibility
and can be added in various cosmetics such as cream, lotion. cosmetic water, essence, milk forfacewashing, liquid for bath, agentfor hair washing and protection, mousse, lip stick. The incorporated quantities are about 0.05%-0.5%.
