pH UP is a unique formulation for those with oily skin. Oily skin has large or dilated pores, shiny complexion, blackheads and pimples. The oiliness of the skin can change from day to day, depending on the sun, wind, time of the year, and weather. The oil glands produce excessive lipids.. Oily skin generally occurs when skin’s pH levels are too low (also known as acidic). pH UP helps to increase skins natural pH levels by reducing oil and impurities. The improved formula includes aloe, chamomile and Vitamin E and effectively removes oil and dirt without irritation. This soft mild cleanser is gentle and leaves skin feeling smooth. Dermatologist tested.
