Acetyl Heptapeptide-4 is a synthetic heptapeptide designed to enhance skin hydration, improve skin barrier function, and support moisture retention. It is often used in formulations targeting sensitive, dehydrated, or compromised skin, helping reinforce the skin’s natural defense mechanisms while promoting a smoother, more supple texture.

• Moisturizing creams and lotions

• Soothing serums for sensitive skin

• Post-treatment skin repair products

• Hydration-boosting facial masks

Acetyl Heptapeptide-4 is believed to act by stimulating aquaporin expression, enhancing the skin's water transport mechanisms, and improving cellular hydration. It may also help in tight junction regulation, strengthening the skin barrier and reducing transepidermal water loss (TEWL).
