In her latest Instagram post , Dr. Pimple Popper helps yet another patient deal with the skin condition known as solar comedones. Similar to the ' Fireman Blackheads ' that Dr. Pimple Popper aka, dermatologist and TLC hos t Dr. Sandra Lee, MDtreated last week, solar comedones tend to pop up on areas of the skin that have been exposed to sunlight for a very long time, usually over a period of months or even years. While they may look just like blackheads, they can technically be blackheads or whiteheads depending on whether or not the comedones are open, according to DermNet .

Likewise, the process for treating them is much the same as it is for any blackhead: In lieu of her usual comedone extractor, Dr. Lee instead uses a pair of tweezers to gently squeeze each of the comedones, releasing the sebum inside. ("I'm getting good at pimple porn," Dr. Lee jokes. "That's what it feels like.")

Thankfully, they're also relatively easy to prevent. The most obvious solution? Wear sunscreen, or use a daily moisturizer with SPF. Here are a few of our favorite expert-approved picks .
