The molecular size of pyruvic acid is larger than that of the more commonly used AHAs. Its applications range from skin moisturising to wrinkle reduction to deep chemical peeling. They work by exfoliating our skin and speeding up the normal skin cell rejuvenation cycle.

Pyruvic acid, like all AHAs, enhances skin texture and improves the signs of ageing by stimulating cell shedding in the epidermis's outer layers and enhancing hydration.
