If you suffer from acne, the idea of putting lotion on your face may seem like you're asking for trouble: Acne is usually caused by excess oil and clogged pores, after all, so why would you want to slather on a product that's coats your face and adds moisture? Because healthy moisture and unhealthy dirt and oil are different things, and because not all lotions will clog your pores. The important thing is to choose a product that's meant for your skin type and incorporate it correctly into your existing skin-care routine.
Not all people who are prone to acne have very oily skin, but the two do tend to go hand in hand. If this sounds like you, you'll want to choose a moisturizer that's oil-free and not too thick or creamy. (Most will say "oil-free" on the package, but you can also look for ingredients that end in "icone," like silicone -- a hint that the product is mostly water-based.)

Another option is to try a moisturizer that has built-in acne fighters. Look for a lotion that contains salicylic acid, says Cheryl Karcher, MD, a dermatologist in New York City; this gentle acid causes the top layer of skin to soften and peel off, getting rid of dead skin cells that may be clogging pores and letting clean, fresh skin underneath come to the surface.
"Salicylic acid lotions can be more effective than salicylic acid face washes, since they stay on your face for a longer period of time and will continue working throughout the day," says Karcher. But use these with caution: If you're already using another salicylic acid product or a prescription-strength acne product with retinol, she warns, the combination of the two may be too drying for your skin. You may need to choose just one or the other, or cut back on how often you use one or both products.
Some moisturizers contain alpha hydroxy acids (or AHAs) like glycolic acid. These are also chemical exfoliators that works to slough off dead skin cells, and are a good choice for people who have dry skin but are still prone to acne, redness and discoloration and irritation. [Libov, Suszynski]
