Dermatologists, estheticians, and all-around skin experts worldwide endlessly extol the virtues of using exfoliating acids to treat common skin complaints like acne, hyperpigmentation, and blackheads.

When used by professionals with extensive skin training and in a controlled, sterile environment, these treatments are safe. However, experts have discovered that high-strength acids are landing in the laps of individuals with no expertise whatsoever, and the results are incredibly dangerous.
