Tetrapeptide-30 is a synthetic peptide composed of four amino acids, typically modified through acetylation to enhance its stability and transdermal absorption efficiency. Its molecular design mimics specific cell signaling fragments, allowing it to target melanocytes or related pathways in the skin. As a whitening active peptide, Tetrapeptide-30 is attracting attention for its multi-faceted inhibitory effect on tyrosinase activity and is commonly used in high-end whitening and skin brightening skincare products.

Targeted Inhibition of Tyrosinase Activity: Tetrapeptide-30 directly inhibits the catalytic function of tyrosinase by competitively binding to its copper ion active site, blocking the first step of melanin synthesis. It also downregulates the expression of tyrosinase-related proteins, reducing melanin production through multiple pathways.
Anti-inflammatory and Antioxidant-assisted Whitening: This ingredient inhibits the melanocyte signaling pathway activated by UV radiation or inflammatory factors, reducing post-inflammatory hyperpigmentation. Its antioxidant capacity protects melanocytes from free radical activation, indirectly inhibiting excessive melanin production.
Blocking Melanin Transfer: Tetrapeptide-30 interferes with the transfer of melanosomes from melanocytes to keratinocytes, preventing the diffusion of already produced melanin into the epidermis, thus preventing the formation and deepening of age spots.
Improving Skin Microcirculation and Metabolism: By promoting local microcirculation, it accelerates the metabolism and shedding of keratinocytes containing melanin, helping to brighten skin tone. It also contributes to improving overall skin health.
Whitening and Spot-Fading Skincare Products: As a core whitening ingredient in serums, creams, and masks, it specifically targets and improves pigmentation problems such as melasma, sun spots, and acne marks. Suitable for uneven skin tone, dullness, and skin requiring prevention of dark spots.
High-End Whitening and Anti-Aging Synergistic Products: Combined with whitening ingredients such as vitamin C derivatives, niacinamide, and arbutin, it creates a multi-pathway whitening system to enhance overall brightening effects. Added to anti-aging products, it improves skin tone while reducing fine lines, achieving comprehensive rejuvenation.
Specialized Area Care: Used in eye whitening products to improve dark circles and pigmentation around the eyes. Added to skincare products for exposed areas such as the neck and hands to prevent and reduce discoloration caused by photoaging.
Post-Treatment Repair and Prevention of Hyperpigmentation: Used in repair products after medical aesthetic procedures such as laser and IPL treatments to prevent post-inflammatory hyperpigmentation and accelerate even skin tone recovery. As a daily protective product, it reduces the negative impact of environmental factors such as UV rays on skin tone.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
