It is effective in all temperatures and altitudes, both hot and cold, and makes an ideal base to apply lipstick to.
Love Ultrasun suncare! This lipbalm nourishes with spf 30 and it doesn't leave a white cast on the lips. Would recommend. Works well under makeup and lipstick.
This is the best lip sunscreen I have ever used and I would never use any other brand now.
Very conditioning used for a holiday to prevent lips going red and dry and it was fab!
