Decapeptide-4 (CAS No. 72957-37-0) is a synthetic bioactive peptide composed of ten amino acids that mimics the structure of natural growth factors found in the human body. Known for its powerful anti-aging, wrinkle-reducing, and hair follicle revitalizing effects, Decapeptide-4 is widely used in advanced cosmetic formulations such as anti-aging creams, serums, hair restoration tonics, and scalp care solutions.
This peptide promotes cellular proliferation and extracellular matrix regeneration, primarily by stimulating fibroblast activity and collagen synthesis in the dermis. Clinical and in vitro studies indicate that Decapeptide-4 enhances skin firmness, elasticity, and moisture retention while reducing the appearance of fine lines. In hair care, it plays a critical role in stimulating hair follicle stem cells, improving nutrient delivery, and supporting new hair growth, making it ideal for use in anti-hair loss products.

Dipeptide-15 (CAS No. 556-50-3) is a bioactive short-chain peptide consisting of two amino acids that work synergistically to promote skin hydration, elasticity, and cellular renewal. Recognized for its excellent moisturizing and anti-aging effects, Dipeptide-15 is widely used in high-end skincare formulations such as anti-wrinkle creams, serums, essence lotions, and hydrating masks.
As a naturally inspired molecule, Dipeptide-15 enhances the skin’s natural moisture-retention capacity by stimulating the synthesis of key components in the Natural Moisturizing Factor (NMF) and improving intercellular lipid balance. It helps restore the skin’s smoothness, resilience, and radiance while reducing fine lines caused by dehydration and aging. Additionally, it supports collagen and elastin synthesis, contributing to firmer, younger-looking skin.
Dipeptide-15 is biocompatible, non-irritating, and suitable for sensitive skin applications. Its small molecular size allows it to easily penetrate the epidermis, delivering visible results in hydration and anti-aging care.

Hexapeptide-9 (CAS No. 1228371-11-6) is a bioactive short-chain peptide composed of six amino acids that delivers powerful anti-aging, moisturizing, and skin-repairing benefits. Scientifically known for stimulating collagen synthesis, it enhances skin elasticity, reduces fine lines, and accelerates tissue regeneration.
With its small molecular weight and excellent skin penetration, Hexapeptide-9 acts directly on the dermal matrix, where it promotes the regeneration of structural proteins such as collagen types I and III, fibronectin, and laminin. This activity improves the firmness and smoothness of the skin, making it a popular active ingredient in luxury skincare products, anti-wrinkle formulations, and post-treatment recovery creams.
Numerous in vitro and in vivo studies have demonstrated that Hexapeptide-9 can significantly reduce wrinkle depth, enhance dermal density, and restore youthful smoothness when used consistently. It is non-irritating, biocompatible, and suitable for all skin types, including sensitive and mature skin.
