Ingredient review
Royal Jelly Ferment Filtrate
INCI: LACTOBACILLUS/ROYAL JELLY FERMENT FILTRATE
A gentle fermented ingredient that may help soothe and condition the skin, though research is still limited.
In plain English
This ingredient is made by fermenting royal jelly (a substance bees produce for their queen) with friendly bacteria. The fermentation process breaks down the royal jelly into smaller, potentially more skin-friendly components. It's used in skincare to help moisturize and calm the skin, and it may also provide some antioxidant protection against environmental damage.
