Oil-based versus water-based sunscreens: This is one of the most important things to keep an eye out for when buying sunscreen to protect your oily or acne-prone skin. People with oily skin types want only the products that are water-based. Choose carefully -- look for labels that say oil-free and noncomedogenic.
If you're trying to limit the number of products you apply to your face every day, look at changing your daily moisturizer rather than adding another product to your skin care arsenal. Swap your oil-free, noncomedogenic lotion for one that contains at least SPF 15, and choose one with a tint if you'd also like to conceal blemishes and skin flaws.
