pHresh 3.5: a new low pH liquid skin cleanser.
pHresh 3.5, a new low pH liquid skin cleanser, was evaluated for safety and efficacy in four clinical studies. In 5- and 21-day predictive patch tests the cleanser was rated mild compared to four other widely used cleansers. As a degreasing agent it was found effective during a 4-week study period, especially in subjects with severe facial oiliness. Daily use of the product for a month in tretinoin-treated acne patients failed to indicate any lack of compatability of the two agents. Resolution of pre-existing skin irritation was not impaired by pHresh 3.5 usage.
