| Description | Acetyl hexapeptide-38 is a tissue repair promoter that targets fibroblasts in the dermis of the skin. It works by promoting collagen synthesis in the dermis and thickening of subcutaneous fat. Acetyl hexapeptide-38 can activate the skin repair mechanism, increase the collagen content in the dermis, Acetyl hexapeptide-38 is a tissue repair promoter that targets fibroblasts in the dermis of the skin. It works by promoting collagen synthesis in the dermis and thickening of subcutaneous fat. Acetyl hexapeptide-38 can activate the skin repair mechanism, increase the collagen content in the dermis, improve the skin tissue structure, and has the activity of promoting local tissue repair. Acetyl hexapeptide-38 can be used in the field of cosmetic medicine to repair congenital soft tissue defects, reduce tear grooves and nasolabial folds, eliminate postoperative scars, and conduct micro-plastic surgery of skin tissue[1]...

RKH acetate can directly bind to Toll-like receptor 4 (TLR4) and block TLR4 signal transduction in immune cells[1] | STh, an Escherichia coli heat-stable toxin, is a 19 amino acid polypeptide encompassing three disulfide bridges. STh is an antigen of interest in the search for a broad coverage enterotoxigenic Escherichia coli (ETEC) vaccine[1] |
