Successfully prevent embarrassing bumps associated with hair removal. Other brands may claim to do this, but because they have a higher pH and fewer active ingredients, their attempts are virtually futile. Plumb Genius is your formidable ally in the battle against ingrown hairs, wax and razor rash, and skin irritation. In addition to herbal extracts and special glycerin-based humectants for moisture retention, this smart formula has a pH of 4.4, which facilitates the effectiveness of alpha hydroxy acids. Especially great for sensitive skin and safe to use for those with aspirin sensitivities. 3.38 oz.
