READ MORE

The 3.8/5 efficacy score reflects a mild surfactant system led by disodium cocoamphodiacetate, disodium laureth sulfosuccinate, and potassium cocoyl glycinate, with a reported pH around 5.5; that is appropriate for cleansing but does not justify meaningful credit for the rinse-off hyaluronic acid, beta-glucan, extracts, or tocopherol. The formula lacks harsh primary sulfates/sulfonates and fragrance, supporting a strong safety score, while its marketing ingredients provide little lasting benefit during brief contact.
