Every product you've used goes after the growths that are already there. Nothing has gone after the keratin buildup that keeps producing them. Fora is the first leave-on dual-acid body stick built to break down hardened keratin with hours of sustained contact. 7% glycolic acid on the surface. 0.5% salicylic acid underneath. 10% shea butter to protect skin that doesn't need one more thing working against it.
