Products Description

Pentapeptide-18 peptide is an artificially synthesized small molecule linear pentapeptide, It is also a structurally optimized enkephalin mimic. It has a mature and stable molecular structure. Its standard amino acid sequence is Tyr-D-Ala-Gly-Phe-Leu. Different from the natural leucine brain啡 peptide, it achieves structural modification by replacing the natural L-alanine with D-proline, significantly enhancing the molecular stability and skin permeability. At room temperature and normal conditions, Pentapeptide-18 peptide is a white, uniform and loose powder. The powder has high fineness and no visible impurities under the naked eye, which is a typical appearance characteristic of high-quality peptide raw materials. It has almost no smell, and a few high-purity batches may have a very faint amino acid original flavor, which will not interfere with the final fragrance of the skin care product. Pentapeptide-18 peptide has excellent water solubility and can dissolve quickly in water. After dissolution, the solution is clear and transparent. It is completely insoluble in organic solvents such as oils and alcohols, and is suitable for all water-based skin care systems.

Products function

Pentapeptide-18 can gently regulate the nerve-muscle conduction of the skin, relieve the tense muscle state of the face, and reduce the repeated pulling of the skin caused by frequent expressions. Long-term use can effectively fade dynamic lines such as smile lines and fine lines around the eyes, reducing the formation of these lines at their source. Compared with traditional aggressive anti-aging ingredients, it has a mild and non-stiff effect, and will not disrupt the natural facial expression state.

On the basis of relaxing the muscles, Pentapeptide-18 can assist in repairing the dermal texture of the skin, improving the slack and tired appearance of the skin caused by long-term stretching and aging, and enhancing the smoothness and firmness of the skin. It has a good intervention and improvement effect on dry lines, fine lines of the early-aged skin, and the sagging lines of mature skin. It effectively delays the aging process of the skin and achieves a long-term effect of anti-aging and stability.
