Hyaluronic acid is a high molecular weight polysaccharide with D-glucuronic acid and N-acetyl-glucosamine as repeating structure unit.Because of the action of hydrogen bond between the monosaccharide in HA linear axle,HA molecular forms a rigid screw column structure in space.Strong hydrophilic properties exist due to the large amount of hydroxyl groups. Furthermore,HA has a special water binding function and binds its water very strongly,so that it has strong water retention. Theoretically its binding water capacity is up to 500 ml/g as an ideal natural moisturizing factor. HA is also one important component of the skin.It can prevent skin from aging and improve the appearance and tactile sensation of skin. A part of low molecular weight HA can penetrate into dermal layer to control the mid-metabolism,and make the skin moist, smooth and elastic.Therefore the cosmetic functions of HA are its resistance against skin wrinkles and its general health protection.HA is not only a good skin moisturizer,but also promotes cell's metabolism of skin.So HA stands for bio-mimetic cosmetics.The content of hyaluronic acid in body will decrease as they are aging,oral hyaluronic acid supplementation can supplement HA in body and improve skin conditions,moisturizing skin from the inside out,smoothing out wrinkles during cell metabolism.Oral hyaluronic acid Supplementation is very popular in Japan,USA and other western countries. Hyaluronic acid is a natural part of the human body why it is highly suitable for many applications within the field of medicine  and  related  aids.It  is  used  in  ophthalmology,orthopedics  and  cosmetic  surgery.With  the  researching  and development of application in medicine area,hyaluronic acid's application as HA-supplementation and medical treatment material will be one major stream in health care Industry.

Hydroxyapatite (HAP), also known as hydroxyapatite and basic calcium phosphate, is a natural mineralization of calcium phosphate (Ca5(PO4)3(OH)). However, it is often written in the form of (Ca10(PO4)6(OH)2) to emphasize that it is composed of two parts.

     Surfactant, also known as interfacial active agent, is a compound that can significantly reduce the surface tension or interfacial tension between two liquids, liquid gas, and liquid solid. Surfactants are divided into ionic surfactants (including cationic surfactants, anionic surfactants, amphoteric surfactants), non-ionic surfactants, amphiphilic surfactants, etc.

Conditioning agents is mainly used to improve the texture of hair, making it smooth, soft, easy to comb, and has a shaping effect.

Silicone oil is a kind of polysiloxane formed by alternating arrangement of silicon and oxygen. It has a silicon oxygen bond (Si-O) chain structure and usually exists in the form of liquid or gel. It has excellent chemical stability and high temperature resistance. Silicone oil has good film-forming properties, hydrophobicity, breathability, and physiological inertness. It can form a soft and breathable protective film on the surface of the skin, keeping the skin hydrated and smooth. Silicone oil is widely used in cosmetics, providing excellent protection and improvement functions.

Emollients are cosmetic components that help maintain the softness, flexibility, and smooth appearance of the skin. The function of Emollients is to remain on the surface of the skin and provide lubrication within the stratum corneum. Usually filling the space on the surface of the skin, replacing the lost lipids in the stratum corneum, reducing scaly skin, and improving skin appearance.

Vegetable oil is a compound formed by the reaction of higher fatty acids and glycerol, widely distributed in nature. It is an oil obtained from the fruits, seeds, and germ of plants, such as peanut oil, soybean oil, flaxseed oil, castor oil, rapeseed oil, etc. The fatty acids in vegetable oils can moisturize and brighten the skin, and are widely used in cosmetics.
