Essential Oil is a highly concentrated volatile aromatic oily liquid extracted from the flowers, leaves, roots, stems, fruits, seeds, bark, and other parts of aromatic plants through physical methods such as distillation, pressing, and extraction.

definition Monomer flavor refers to the flavor compound with single component and clear molecular structure, which is the basic raw material for preparing various essence. Unlike natural essential oils (mixtures containing hundreds of ingredients), monomeric fragrances are pure single aromatic chemicals.

PCA Zinc (Zinc PCA) = Zinc Pyrrolidone Carboxylate, a complex of "zinc + natural moisturizing factor PCA". It is water-soluble, mild, oil-controlling, anti-acne, and moisturizing, commonly used for oily skin, combination skin, and acne-prone skin. I. Basic Information Full Name: Zinc Pyrrolidone Carboxylate (Zinc PCA)  INCI: Zinc P CAS: 15454-75-8  Appearance: White powder, easily soluble in water  Structure: Zinc ion + PCA (pyrrolidone carboxylic acid), PCA is a natural moisturizing factor (NMF) inherent to the skin

Tocopheryl Acetate, also known as vitamin E acetate, is a stable form (fat-soluble) of vitamin E, commonly found in skincare products, food, and health supplements. Basic Information Alias: Vitamin E Acetate, dl-α-Tocopheryl Acetate CAS: 7695-91-2  Appearance: Light yellow viscous oily liquid, almost odorless  Characteristics: More stable (less prone to oxidation) than natural vitamin E, better heat and light resistance, and it is converted into active vitamin E after absorption by the human body.

Nicotinamide, also known as nicotinic acid amide, is an amide compound of nicotinic acid. As a derivative of vitamin B3, nicotinamide is listed by the National Medical Products Administration and authoritative medical dictionaries, with clear functions and effects. It is widely used in skin care and medical fields. Not only is it an important coenzyme component for maintaining normal human metabolism, but it is also recognized as an "all-rounder" in the skin care industry, excelling in whitening, repairing, and oil control.

D-Panthenol is a widely used vitamin B nutritional supplement, extensively applied in fields such as medicine, food, feed, and cosmetics, particularly in skin pharmaceuticals, skincare, and hair cosmetics. D-panthenol, commonly known as vitamin B5, is a B-group vitamin and the dextrorotatory isomer of panthenol. Upon entering the human body, D-panthenol can be converted into pantothenic acid, which then synthesizes coenzyme A, promoting the metabolism of proteins, fats, and carbohydrates in the body. It protects the mucous membranes on the skin surface and maintains the luster of hair. A deficiency of D-panthenol can lead to skin lesions and physiological disorders.

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.
