Q: My lips get dry and crack (and bleed, I know - yuk) so thats why I need to wear it! Salam
A: I think it's better to avoid it since you will lick it off. Put it on in the evening. By the way, Vaseline doesn't moisturize lips. You might want to try some more natural lip balm. Vaseline is a petroleum product. Dry cracked lips means you are dehydrated.
