Description
Yon-Ka Le Sérum is for skin that has started to look tired, and less firm and bouncy than it used to.
The most concentrated formula in the Excellence Code range, it pairs phyto-fermented jasmine for firmness and vitality with Alpine willowherb and a pre and postbiotic complex. The milky texture sinks in fast, with a soft jasmine and neroli scent. In the brand's testing, skin hydration rose 72% after one hour, and over time skin looks firmer and smoother, with less visible pores. 99.5% of its ingredients are of natural origin.
Follow with La Crème or your usual cream.
