Undecylenoyl Phenylalanine (Sepiwhite MSH) is a mild multi-effect whitening cosmetic active, inhibiting α-MSH to suppress melanin production, fading pigment spots and evening uneven skin tone, widely used in brightening serums, spot essences and facial creams.
Undecyl phenylalanine (More White UP) has good skin-friendly properties and can control the binding of α-MSH (melanocyte stimulating H) to melanin production factor, thereby blocking the formation of melanin.
Blocking α-MSH can be achieved at a concentration of 0.001%, with an optimal use concentration of 1%. Comprehensive inhibition of melanin production from multiple links, the effect is more obvious and lasting.
