Science
Mechanism of Action
This heptapeptide functions as a probiotic mimetic, nurturing a diverse and harmonious microbial community on the skin's surface by increasing beneficial bacteria. It enhances the skin's natural immune response against harmful microbes and strengthens the physical barrier by improving cellular adhesion and dermal cell cohesion. Furthermore, Acetyl Heptapeptide-4 stimulates the synthesis of vital proteins such as collagen and elastin, thereby improving skin elasticity, reducing the appearance of fine lines and wrinkles, and boosting overall hydration.
