Flexitol Lip Balm SPF50+ is a concentrated formula containing a synergistic blend of ingredients specially designed to hydrate lips, keeping them smooth and healthy looking. It contains 2.5% urea which removes dead skin cells to allow moisturizing emollients to access deep into skin to replenish lost moisture. Petrolatum sticks to skin and works like a barrier to prevent further moisture loss from dry lips and keeps balm on site of application. Menthol acts as analgesic to alleviate the soreness and discomfort associated with dry lips.Â
