^{【Product Overview】 We are a specialized global supplier of Tetrapeptide-30, a highly intelligent skin-brightening peptide famously known by the trade reference TEGO® Pep 4-Even. Unlike traditional whitening agents that cytotoxicity kill melanocytes, Tetrapeptide-30 works via a dual mechanism: it inhibits the Tyrosinase activation pathway while simultaneously suppressing the inflammatory cytokines (IL-6, IL-8) that trigger pigmentation. We provide high-purity, cosmetic-grade powder to formulators developing treatments for Post-Inflammatory Hyperpigmentation (PIH), acne marks, and age spots.}

^{【Key Advantages】}

^{Targeting PIH (Acne Marks): Its standout feature is treating Post-Inflammatory Hyperpigmentation. By reducing the skin's inflammatory response to UV and acne, it prevents the formation of dark spots left behind by breakouts. It is the "Smart Choice" for acne-prone skin lines.}

^{Dual-Action Mechanism:}

^{Anti-Inflammatory: Significantly reduces the expression of key inflammatory mediators (Interleukins).}

^{Melanin Inhibition: Downregulates the expression of the POMC gene (the precursor to MSH) and inhibits the activation of Tyrosinase.}

^{Safe for Ethnic Skin: Many whitening agents are too harsh for darker skin tones (Fitzpatrick IV-VI). Tetrapeptide-30 is non-irritating and uniquely effective on ethnic skin, reducing the contrast between hyperpigmented spots and normal skin.}

^{Excellent Stability: Unlike Vitamin C or Kojic Acid, Tetrapeptide-30 is chemically stable, compatible with glycolic acid, and does not oxidize or change color in formulations.}

^{【Logistics & Service】}

^{Cosmetic Grade Quality: Manufactured under strict cGMP guidelines for cosmetic ingredients, ensuring high purity and safety.}

^{Global Export: We are experienced in shipping cosmetic peptides globally. We provide full HS Code support (typically 2937.19 or 3504.00) and COA/MSDS documentation.}

^{Formulation Advice: This peptide is robust. It can be added to the water phase and withstands temperatures up to 40°C. Ideal for pairing with Niacinamide for a synergistic brightening effect.}
