Lactobionic acid is derived from the oxidation of lactose.
It is an aldobionic acid comprising one molecule of sugar galactose and one molecule of gluconic acid attached via an acetal linkage.
Lactobionic acid on the skin retains atmospheric water together with the water contained in the cosmetic with very strong bonds, thanks to its chemical structure like a glycosaminoglycan, creating a gel with a high degree of skin hydration with an emollient and protective acid that contains the 14% of water.
Functions:
- Prevent and reverse the appearance of photoaging lines and wrinkles, uneven pigmentation, enlarged pores, and roughness; promote firmness by inhibiting the MMP enzyme responsible for degradation of collagen and consequent wrinkling and skin laxity.
- More effective, safer, and better tolerated than glycolic acid (alpha hydroxy acids) to exfoliate and help smooth the skin
- The safety and efficacy can be further increased by using natural alkyopolyglucoside-based vehicle instead of polyethylene glycol emulsifier (PEG)
- Antioxidant: scavenges free radicals and inhibits lipid peroxidation.
- Skin lightening: Suppresses melanin production in cultured mouse melanocytes in the presence of an analog of a melanocyte stimulating hormone 6% lactobionic acid in an alkylpolyglucoside-based emulsion led to market decrease in the melanin index after being applied to skin sites on the forearm for only 2 weeks.
- Increased skin hydration: it is a natural humectant and has strong water binding properties and has demonstrated the ability to increase the production of glycosaminoglycans in the skin.
- Enhanced barrier function increases the integrity and cohesion of the stratum corneum and accelerates barrier recovery.
- Increased skin thickness: 8% lactobionic acid increased skin thickness of the forearm by an average of 6.9% after 12 weeks, compared to a 1.9% increase in untreated forearms.
