About

Apple cider lees is a fermentation byproduct containing yeast remnants, organic acids, and pectin, used in cosmetics for its astringent and exfoliating properties, though it may contain residual alcohol.

Apple Cider Lees is listed in the EU CosIng database under 'skin conditioning.' It is a byproduct of apple cider fermentation containing yeast (Saccharomyces cerevisiae remnants), acetic acid, malic acid, and pectin. The ingredient carries some risk of residual alcohol content, which is regulated under EU cosmetics law. The SCCS notes that cosmetic products should contain less than 1% alcohol to avoid classification requirements. No EU maximum concentration limit is specified for the lees itself.
