Lemon Peel Bioferment is a skin lightening ingredient and an effective natural alternative to hydroquinone for use in cosmetic products targeted at preventing melanogenesis by tyrosinase inhibition.
It is produced as a result of macerating whole lemon fruit and incubating it with Lactobacillus lacti (the same bacteria used to produce many fermented food products like cheese and sour cream). This ferment is then further processed to remove the potential allergens, citral and geraniol. The resulting ferment is said to have both anti-tyrosinase and antioxidant activity.
