What is fermented skincare?
⚡ Quick answer: Fermented skincare uses ingredients broken down by microorganisms, like galactomyces, rice or yeast ferments, which Korean brands prize for adding glow and a smoother-looking texture. Fermentation is thought to make some ingredients lighter and more skin-friendly, and it's a signature of many Korean essences.
