 The trendy water bottle is giving you wrinkles. When you repetitively purse your lips around a straw, it can lead to premature wrinkles around your mouth. While wrinkles also have to do with things like genetics, hydration, and sun exposure, dermatologists did find that constant straw use sped up the wrinkle process. You can try to avoid this by not fully purseing your lips around the straw or by just using a cup without one.
