As a peptide derivative composed of modified amino acid, it has structural characteristic of having both hydrophilic and lipophilic groups. It is equipped with not only the ability to hold and suppress evaporation of moisture in the horny layer in skin but also ability to restore the barrier function of the skin.
INCI NAME: DECARBOXYLMETHYL PALMITOYL PENTAPEPTIDE-67
Patent application No.: 40-2019-0045396

It is a compound synthesized by chemically binding peptide that promote generation of vitamin C and collagen, and has more outstanding ability to form collagen that those of each vitamin C and peptides it generates. In addition, it has the effect of suppressing MMP-1(MATRIX METALLOPROTEINASE-1) that disintegrates collagen.
INCI NAME: ASCORBYL SUCCINOYL TETRAPEPTIDE-21
Patent application No.: 40-2019-0045398

It contains penta-peptides-4, which is composed of KTTKS as the key 5 sequences of Type I collagen, and is known to promote the manifestation of TYPE I and III collagen, and FIBRONECTIN. In addition, PALMITIC ACID, a fatty acid, is bound to penta-peptides-4 in order to increase skin penetration. This compound has the function to improve and prevent wrinkles through generation of collagen, and restoration of damaged skin due to UV ray and external irritations.

It contains the key 6 sequences of SNAP-25 protein involved in the secretion of acetylcholine, which is a neurotransmitter. It is a peptide with acetylated N terminal and the C terminal in amide format. This compound is equipped with the mechanism of inhibiting muscle contraction by suppressing the secretion of acetylcholine and function to reduce the depth of wrinkles around the eyes and in the forehead.

It is a compound with strong chelation of copper (II) ion to the GHK 서열의 tri-peptides substances in GHK range. This compound is known to be effective in treatment of wounds, and as anti-oxidant and anti-inflammation agent. It plays the role of stimulating the synthesis of collagen and glycosaminoglycan in the fibroblast as well as promoting generation of blood vessels in the skin.
