Pentpeptide-18 is a modified cerebral peptide that can be bonded in nerve extracellular and cerebral peptide receptor, and the G protein group (α, β, γ) can be released. Such calcium ion channels are closed, and the vesicles cannot be fused, resulting in acetylcholine release, and neurons are in a non-excited state.

Acetyl Pentapeptide-18 has a good skin conditioning effect. When used in cosmetics, it can penetrate the dermis and increase collagen. It can effectively reshape the skin, delay the aging process of the skin, and maintain the skin's youthful state.
