Dermalogica PreCleanse is a deep-cleansing oil that melts impurities and make-up from skin. PreCleanse thoroughly melts away layers of excess sebum (oil), sunscreen, waterproof make-up, pollutants and products that build up on skin, allowing your prescribed Dermalogica Cleanser to penetrate even further for professional cleansing results. How to use: Dispense into dry hands. Massage over dry face and eyes to dissolve surface oil and dirt. Concentrate on areas of congestion or stubborn debris. Wet hands and continue massaging to create a light, milky emulsion. Rinse with lukewarm water.
