The Strong Acid

Formulated for experienced acid users, The Strong Acid is our strongest liquid exfoliant, combining the power of alpha-, beta- and polyhydroxy acids (AHAs, BHA and PHA) into one powerful formula.

This next-generation acid toner works hard to smooth skin texture, banish dullness and reduce the appearance of fine lines and wrinkles. Glycolic, lactic and mandelic acids work alongside shikimic and phytic acids to deliver AHA-powered resurfacing, supported by gluconolactone (PHA), while salicylic acid works to decongest the skin. Formulated at an optimally low pH for effective resurfacing, this is our most advanced exfoliating acid for experienced users.
