The order of your skin care routine is important, especially when you're working with products that tend to dehydrate skin. First, wash with a mild cleanser and gently dry your skin. Apply any topical products you use to treat or prevent acne flare-ups next. Then, it's time for a light moisturizer. Applying a daily lotion to oily skin will help reduce the dryness, redness and irritation both prescription and over-the-counter blemish and oil control products can cause. What you might not know, though, is that routine daily moisturizing can also help those treatments work better, because you'll be using them on healthy, smooth skin.
