What Dermatologists Know About Wrinkles That You Don't

"Line-free lips are a sign of youth, beauty and sexuality," says Marina Peredo, MD, a board-certified dermatologist and an associate clinical professor of dermatology at Mount Sinai Hospital in New York. "When lips age, they get thinner and develop wrinkles, which, in some cases can become very visible," she says. Because people tend to focus on someone's mouth as he or she talks, the lines on and around lips tend to age us the most. That's why Peredo recommends patients tackle wrinkles here when they want to make the biggest impact. An OTC lip treatment with anti-agers like peptides may bolster collagen production and help smooth out these lines over time, while lip moisturizers with hyaluronic acid may provide a temporary plump.
