In an Instagram Live, consultant dermatologist Dr Anjali Mahto also spoke about the viral trend. “Theoretically, if you’re asking me whether glycolic acid can help dry feet, I suppose it can,” she said. “It’s an exfoliating acid and if you have a lot of hard, dead skin on your feet, then probably, using a little bit of glycolic acid will help that.” Dr Mahto goes on to say that the stratum corneum (the top layer of skin) is super thick on the soles of our feet. “If you have a thick stratum corneum that has built up, using glycolic acid could help that. It makes total sense.”
