Cosmetic anti-ageing lipopeptide (Palmitoyl Tetrapeptide-7)

Description

Rigin 200mg (Palmitoyl Tetrapeptide-7) (Topical) is a high-purity, research-grade cosmetic peptide supplied as a lyophilised powder for topical formulation and in-vitro studies. Rigin is the trade name commonly used for palmitoyl tetrapeptide-7, a lipopeptide with the sequence Pal-Gly-Gln-Pro-Arg (Pal-GQPR), originally developed to mimic part of the immunoglobulin G (IgG) molecule. In experimental models, palmitoyl tetrapeptide-7 has been investigated for its ability to modulate cytokine activity (especially interleukin-6), reduce inflammation, support extracellular matrix homeostasis and stimulate collagen and elastin synthesis in the skin. These properties make it of interest in anti-ageing and skin-repair research, where it may help improve firmness, elasticity, hydration and overall skin texture when incorporated into topical test formulations. This product contains 200 mg of palmitoyl tetrapeptide-7 at ≥99% purity (HPLC) and is labelled for research use only, not for human or veterinary use.

Bnefits

Provides a defined, high-purity source of palmitoyl tetrapeptide-7 (Rigin) for cosmetic and dermatological research.
Investigated for stimulating collagen and elastin synthesis, supporting improved skin firmness and elasticity in experimental systems.
May help reduce the appearance of fine lines and wrinkles and improve overall skin smoothness in topical formulation studies.
Shown in research models to modulate cytokine activity (e.g., IL-6), potentially reducing inflammation-related damage to the extracellular matrix.
Associated with improved skin hydration, barrier support and smoother texture when formulated appropriately in test products.
Lipid (palmitoyl) modification enhances peptide affinity for skin and potential penetration in topical research formulations.
Supplied as a lyophilised powder at ≥99% HPLC purity for reproducible formulation and in-vitro work.
Research-use-only labelling supports safe, controlled use in non-clinical environments.

Indications

In-vitro and ex-vivo research on skin ageing, inflammation and extracellular matrix regulation.
Development and testing of experimental topical cosmetic formulations targeting wrinkles, firmness and elasticity.
