System Verdict
Excellent gentle cleanser with optimal pH and amino-acid surfactants—a benchmark drugstore formula. This cleanser scores high on efficacy because it accomplishes its core job flawlessly: it removes impurities without stripping the skin barrier. The formulation uses three amino-acid surfactants (Sodium Cocoyl Isethionate, Sodium Methyl Cocoyl Taurate, Potassium Cocoyl Glycinate) positioned in the top 7 ingredients, ensuring effective yet gentle cleansing. The pH is buffered to 5.5 via Citric Acid and Sodium Acetate—ideal for maintaining skin's natural acid mantle. Glycerin, Panthenol, Caprylyl Glycol, and Pentylene Glycol provide humectant support, preventing the tight, stripped feeling common with harsh cleansers. Madecassoside (centella asiatica derivative) adds barrier-repair benefits. The formula contains no sulfates, no harsh surfactants, and no fragrance—eliminating irritation risk. The only minor limitation is that this is a rinse-off product, so the soothing and conditioning ingredients deliver temporary benefits rather than lasting treatment effects, but that is not the cleanser's job.
