Acetyl Tetrapeptide-3

Acetyl Tetrapeptide-3

Overview
Acetyl Tetrapeptide-3 is a synthetic signal peptide widely used in cosmetics and skincare products. It is renowned for mimicking a functional fragment of Laminin, a critical protein found in the dermal-epidermal junction (DEJ), also known as the basement membrane zone. The DEJ is the crucial layer that connects the epidermis (outer layer of skin) to the dermis (deeper layer). The primary role of Acetyl Tetrapeptide-3 is to improve skin firmness and elasticity by reinforcing this connecting layer.
