System Verdict
This is a decent but not especially gentle cleanser: the surfactant blend does the job, but sodium coco-sulfate keeps it from being truly standout. The efficacy score is held in the good-but-not-excellent range because the formula has a mix of milder surfactants and humectants, yet a sulfate surfactant sits in the top half of the INCI and can increase cleansing strength and potential barrier stress; the soothing ingredients and glycerin help, but they do not fully offset that base.
