If you’ve ever sat with a friend and watched as he or she applied and then reapplied Chapstick or any other type of lip balm repeatedly, there’s a scientific reason for it, according to Samantha Conrad, MD, a dermatologist at Northwestern Memorial HealthCare in Chicago. For starters, the ingredients in some products can end up being super drying, which prompt you to feel the need to keep reapplying in a vicious cycle. “In addition, the feeling of being ‘addicted to Chapstick’ is that the person has become very used to a textural feeling on his or her lips,” she says. “When they don’t have the product on, they feel that something is missing.” Find out what really causes chapped lips.

It’s one thing to use whitening strips regularly to remove red wine and coffee stains. It’s quite another to be addicted to bleaching your teeth. There’s even a term for it: Bleachorexia refers to being addicted to bleaching teeth, says Leslie Renee Townsend, DDS, of Jefferson Dental Clinics, in Dallas. “Overuse or misuse of whitening products such as lasers, strips, gels, rinses, or pastes can cause noticeable sensitivity, tooth pain, gum irritation, and weakened enamel, often temporary, but sometimes more permanent,” Townsend says. “At worst, teeth begin to demineralize with time, since whitening products strip tooth enamel resulting in transparent-looking teeth.”
