MELA serum contains a specialised blend of active ingredients to brighten the skin, providing a more even-toned complexion. 4-Butylresorcinol helps reduce hyperpigmentation by suppressing a key enzyme, tyrosinase, which plays a major role in the process where the skin produces pigment (melanogenesis). Tetrapeptide-30 provides strong skin brightening effects, and neuro-light is an extract from Sand Lily, contributing to a reduction in hyperpigmentation, and assisting towards an even skin tone. Hyaluronic acid low molecular weight provides a boost of hydration and contributes to protect the skin barrier.
