The 3rd Generation Comthing SGS Triple Anti-Irritant Complex, Full Recovery
The Formation Mechanism of Sensitive Skin Sensitive skin: remarkably sensitive to external stimuli (Physical and chemical stimuli, allergens, pathogens etc.) When sensitive skin is formed, it is easier to generate inflammation reaction or the skin inflammation already existed. The destruction of skin barrier function
Skin Inflammation Reaction Mechanism Immunocyte
Sophora Flavescens, as the leguminous plants of Sophora genus, is distributed in Russia, Japan, India, North Korea and northern provinces of China, growing within 1500 meters area. Sophora Flavescens root contains a variety of active alkaloids, main ingredients are D-matrine, D-oxymatrine, D-sophoranole, L-Lanagyrine. Sophora Flavescens root extract with strong anti-inflammatory and anti-allergy effects, as a immune inhibitor, reduce the release of allergic medium, is a good reliever for skin itchy symptoms.

Glycyrrhiza inflata is known as the king of the medicine, belongs to tonic traditional Chinese medicines. Glycyrrhiza inflata root as a well known ancient chinese medicine, has detoxification, anti-inflammatory and anti-allergy effect, and it is testified by modern pharmacology. Glycyrrhiza inflata contains Glabridin, glycyrrhizic acid, Glycyrrhetinic acid, Glycyrrhetinic alkali, Glycyrrhiza metal salts (calcium iron zinc), liquiritin, asparagine, protein and a variety of amino acids, lipids, mannitol,glycyrrhiza polysaccharide, Glycyrrhiza pigment, fruit acid, microelements such as vitamins etc. Ref: Greaf Internal Report. Feb 2016
Effective ingredients of Glycyrrhiza inflata root contains Glycyrrhizic Acid, which is also called glycyrrhizin, 18 - licorice pavilion Acid. Glycyrrhizic acid is decomposed into glycyrrhetinic acid and Glucuronic acid after absorbed by the body, the former decomposed structure has a strong anti-inflammatory activity, and the second has a strong detoxification effect. Glycyrrhizic acid has two isomers, named 18 - alpha - glycyrrhizic acid and 18 - beta - glycyrrhizic acid.
Scutellaria baicalensis as the labiatae plants of the genus Scutellaria, widely distributed in the southwest,northeast and norththern of China. Its root extract contains many kinds of flavonoids, mainly baicalin, radix scutellariae. Scutellaria baicalensis root extract contains a variety of bioactive flavonoids, which can prevent the release of hyaluronidase, thus has good analgesic action.
The Functions of Comthing SGS Reduces the stimulation, protects the skin barrier Anti-Itching, analgesia, relieving Combines active small molecules with biological polysaccharide, controled- release, long-term action.

3D Reconstructed Epidermis Model
3D RE(Reconstructed) Epidermis Model HS(Human skin) Epidermis in vivo 3D RE HS EpiSkin Bat#15ER270915
3D RE Model Introduction:According to EU cosmetics alternative committee(ecvam),the three-dimensional skin is selected as one of the standard model for test cosmetics raw materials stimulation. Principle:Episkin is an in vitro reconstructed human epidermis from normal human keratinocytes cultured on a collagen matrix at the air-liquid interface. This model is histologically similar to the in vivo human epidermis.the human keratinocytes come from mammary samples obtained from healthy consenting donors during plastic surgery. HIV 1 & 2, B and C hepatitis tests are carried out on the donor bloods as well as verification of the bacteriological & fungal sterility of the cells and absence of mycoplasma. Method:5% SLS as stimulator;test MTT, IL-1α and TNF-α after adding the stimulator and test sample. Test sample:0.2% SGS
