Tripeptide-29
Also known as: Tripeptide-29, Collagen Tripeptide
Tripeptide-29 is a collagen-biomimetic tripeptide used in topical skincare to signal fibroblasts toward collagen production. It is studied for firmness, elasticity, and overall skin matrix support.

Mechanism of Action
Tripeptide-29 mimics a sequence found in native collagen and acts as a matrikine-style signaling peptide. When applied topically it interacts with dermal fibroblasts to upregulate procollagen synthesis and extracellular matrix deposition. By reinforcing collagen turnover it aims to improve dermal density, tensile strength, and the appearance of fine lines. Its small size is intended to aid penetration into the upper layers of the skin.

Matrixyl
Matrixyl is a palmitoylated pentapeptide (Pal-KTTKS) used topically to stimulate collagen and extracellular matrix synthesis. It is a widely studied cosmetic anti-wrinkle peptide.
GHK (Basic) (Tripeptide-1)
GHK is a naturally occurring human tripeptide (glycyl-L-histidyl-L-lysine) studied for skin remodeling, wound healing, and tissue regeneration. The copper-free 'basic' form is the parent peptide that readily binds copper in tissue.
Syn-Coll (Palmitoyl Tripeptide-5)
Syn-Coll is a topical lipidated tripeptide designed to stimulate collagen synthesis and improve skin firmness and wrinkle appearance.
