An alkaline PH (oily skin) is an open door to germ contamination. Derma purifies the skin and is highly recommended when acne is present. It is also perfectly suitable to skin with Rosacea, Lupus rash or other problematic conditions. Sensitive and allergic skin will also find relief. .35c per day when used once a day.
