Dipeptide-2

Synonymes : Valyl-Tryptophan, VW, Val-Trp, L-Valyl-L-Tryptophan

In the personal care industry, formulators are constantly seeking actives that deliver visible anti-aging benefits without compromising on safety or stability. Dipeptide-2 has emerged as a standout ingredient in this quest, particularly for eye care and firming products. Its ability to target under-eye bags and dark circles has made it a staple in premium serums, creams, and masks, where consumers demand noticeable results.

Dipeptide-2 is a synthetic dipeptide composed of valine and tryptophan. This small molecule is designed to mimic the action of certain natural peptides involved in skin homeostasis. Unlike larger proteins, its low molecular weight allows for efficient penetration into the skin, where it can exert its biological effects. The sequence Val-Trp is not found in common proteins, making it a unique cosmetic active.

Commercial Dipeptide-2 is typically supplied as a high-purity powder, standardized to ≥98% by HPLC. It is water-soluble and easy to incorporate into various formulations. Its primary mechanism involves stimulating the synthesis of collagen and elastin, while also improving lymphatic circulation to reduce puffiness. This dual action addresses both the structural and fluid-retention aspects of under-eye aging.

Présentation et composition du produit

Dipeptide-2 is chemically synthesized using solid-phase peptide synthesis, ensuring high purity and consistent quality. The molecule consists of L-valine and L-tryptophan linked by a peptide bond. Its structure is optimized for stability and efficacy, with no known skin irritation potential. The product is available as a white to off-white powder, which can be easily dissolved in aqueous solutions for formulation.

As a cosmetic ingredient, Dipeptide-2 is often combined with other actives like hyaluronic acid or vitamin C to enhance its effects. It is compatible with a wide range of pH and temperature conditions, making it suitable for both leave-on and rinse-off products. The recommended usage level is typically 0.5% to 2%, depending on the desired effect.
