HEXAPEPTIDE-39.

Valuable CAS - / SKIN CONDITIONING

HEXAPEPTIDE-39, also known as Acetyl Hexapeptide-39 or Silusyne, is a sophisticated peptide engineered to visibly reduce the appearance of cellulite and refine skin texture. It precisely modulates key regulators involved in adipogenesis, leading to a smoother, more uniform skin surface.

Reduces adipogenesis Decreases lipid accumulation Improves visible cellulite Smooths skin texture Promotes skin uniformity Body contouring

Science

This hexapeptide functions as an antagonist of PGC-1α (Peroxisome proliferator-activated receptor-gamma coactivator 1α), a crucial molecular switch regulating adipocyte differentiation and maturation. By downregulating PGC-1α expression, HEXAPEPTIDE-39 effectively hinders the maturation rate of preadipocytes and diminishes lipid accumulation within adipose tissue. This action translates to a reduction in the thickness and waviness of the dermo-hypodermal junction, thereby mitigating the visual characteristics of cellulite and promoting enhanced skin uniformity without directly burning fat.
