Abstract
The Korean-originated new active ingredient, based on Aureobasidium pullulans, is a pink yeast derived from the Jeju King cherry blossom.

It can be used in serums, lotions and creams formulations because of its specific texture. This article aims to show the relevance of the local flora, how important it is to value and respect it and how nature can always surprise us with the discovery of new active ingredients that can make changes to our bodies, improving their characteristics and appearance.
