Function
1. Improves skin firmness & elasticity
It helps support the skin’s extracellular matrix, which can lead to a firmer, more lifted appearance over time.
2. Boosts collagen-related structure
It works by influencing fibroblast activity and supporting components like collagen and glycosaminoglycans (GAGs), which are important for skin strength and bounce.
3. Helps reduce fine lines and wrinkles (anti-aging effect)
By improving dermal density and skin structure, it can soften the appearance of fine lines and early wrinkles, especially those caused by loss of elasticity.
4. Improves skin density and texture
Regular use in formulas is associated with a smoother, more refined skin surface, often described as “plumping” or “tightening.”
5. Hydration + plumping support
It can also help skin look more hydrated and supple, likely due to improved matrix function and moisture retention.

Description About Acetyl Tetrapeptide-9
Acetyl Tetrapeptide-9 is a peptide ingredient used in skincare, valued primarily for its firming and anti-aging effects.
Acetyl Tetrapeptide-9 strengthens the skin's supporting tissue from within and enhances connections between collagen fibers by stimulating the synthesis of Type I collagen and Lumican, thereby effectively improving skin firmness and elasticity.
By supporting the skin's structural network and promoting dermal remodeling, it can make skin feel firmer and appear fuller.
The support of collagen and lumican production helps improve skin texture and elasticity, which can slow down visible signs of aging.
Clinical studies have shown that formulations with this peptide can improve skin elasticity and reduce the appearance of wrinkles. It has also been studied for its ability to improve lip wrinkles and volume.
