Summary
This product contains beneficial exfoliating acids like glycolic, lactic, and malic acids, which promote skin renewal and hydration. However, the presence of denatured alcohol as a top ingredient is concerning due to its potential to dry and irritate the skin, disrupting the skin's natural barrier. The inclusion of witch hazel offers some anti-inflammatory benefits, but the overall formulation is moderately processed with a significant drying agent, impacting its overall safety and effectiveness.
