Glabridin
Glabridin is considered the most powerful natural lightening active ingredient, and in Japan it is classified as “quasi-drug”.
In particular, the Perfectage line boasts extract of licorice titrated at 40% in Glabridin, with tyrosine kinase inhibitors regulating the bio-synthesis of melanin, therefore very effective on skin spots. This action is confirmed by in vivo and in vitro tests.
