| Description | Acetyl tetrapeptide-15, trade name Skinasensyl, is an acetylated tetrapeptide composed of tyrosine, proline, and phenylalanine, N-terminal acetylated and C-terminal amidated. As a neurotransmitter inhibitor peptide, it acts on sensory neurons, limiting the release of pro-inflammatory neuromediators (such as substance P, calcitonin gene-related peptide CGRP, etc.), reducing skin hyperreactivity, thereby alleviating skin discomfort such as stinging, burning, and itching, and improving sensitive skin conditions. Studies demonstrate that it significantly reduces skin response to stimuli, improving skin comfort and tolerance. Widely used in soothing, anti-sensitive, repair skincare formulation development, and cosmetic mechanism research, especially suitable for sensitive skin and post-procedure repair products. |

| PEP-ACT015 | Acetyl tetrapeptide-15 with high-stable acetylation boosts collagen & elastin synthesis for anti-aging | Acetyl tetrapeptide-15 is a highly stable anti-aging tetrapeptide with acetylation modification. N-terminal acetylation end-capping significantly improves peptide enzymatic resistance and skin tolerance. It efficiently acts on dermal fibroblasts to synchronously promote the synthesis of type Ⅰ collagen and elastin, increases dermal thickness and elasticity, and improves skin laxity and static fine lines. It also has good formulation compatibility and can be widely used in various anti-aging, firming and repair skincare formulation systems. | Skin anti-aging research, fibroblast function study, elastin regulation study, anti-wrinkle skincare product development, acetylated peptide application | Fibroblast activation pathway; collagen-elastin synthesis regulatory pathway |
