Whenever I go for long road runs or cycling sessions in direct sunlight, my lips end up completely fried by a combination of UV exposure, windburn, and constant sweat. Regular moisturizers wipe off after ten minutes of intense activity, and standard sunscreens feel super heavy, bitter, and uncomfortable when you're breathing hard. Does anyone have a go-to active lip shield that actually stays locked in place during heavy sweat while offering proper broad-spectrum sun defense?
