Nothing is more important for acne prone skin than protecting it against sun and environmental damage. The sun works as your worst enemy by producing free radicals, damaging skin cells, and beginning the whole cascade of cell damage, causing infections, inflammation, and the formation of acne and wrinkles. The products that we recommend are specifically formulated for oily skin. Sunscreens should be reapplied after swimming, exercise, and in very hot or humid climates.
