Kojic Acid acts on the melanocytes to inhibit melanin synthesis: it blocks the transformation of L-tyrosine (an amino acid that is a melanin precursor) suppressing free tyrosinase, primarily through the chelation of copper ions.

By inhibiting melanin synthesis, Kojic Acid acts as a powerful skin whitening agent, as it helps gradually lighten dark spots on the skin, reducing the cell damage caused by excessive exposure to the sun.

DSP-Cream SPF 50+, DSP-Cover Stick and DSP-Mask are products in the Pigment Zero depigmenting range that contain this depigmenting active ingredient.
