A MUST-HAVE brightening facial that focuses on the use of a skin brightening ampoule containing 7 types of Giga White extracts. What is Gigawhite? The development of Gigawhite is the result of a research program in which over a hundred plants were tested for their tyrosinase inhibiting effects. Of the hundred plants tested, 15 were selected for their tyrosinase inhibitory properties in vitro and then tested on cell cultures. In the cell cultures, 7 plants showed significantly higher tyrosinase inhibitory activity. These ingredients are the secret of the skin-lightening and brightening effect of the facial care.
