Lactobionic Acid (100 Ppm)
Lactobionic acid is a polyhydroxy acid (PHA), also referred to as bionic acid or aldobionic acid, with the chemical name 4-O-Beta-D-Galactopyranosyl-D-Gluconic Acid (CAS #96-82-2). It is considered a next-generation AHA that gently exfoliates dead skin cells while also providing moisturizing and skin barrier-supporting properties. It functions as both an exfoliant and a buffering agent according to official CosIng classification.
Lactobionic acid gently lifts off dead skin cells to smooth and even skin tone, while simultaneously moisturizing and supporting the skin barrier. It offers anti-aging benefits and antioxidant activity, and is notably well-tolerated on sensitive skin and post-cosmetic procedure skin, with less irritation potential than traditional AHAs.
As a PHA/exfoliant, general caution around use with other active exfoliating acids applies; however, the source notes it is suitable for sensitive skin and post-procedure use, suggesting a lower irritation risk than AHAs. No specific photosensitivity or contraindications are explicitly mentioned in the source.
