I know "Vaseline" anything gets a bad rap but it really is one of the best things for dry lips. The molecules in Vaseline, and Vaseline products, are too big to penetrate the skin, rather it seals the moisture in the lips and prevents things like the wind and cold from stripping it out. I'm one for natural products but I still use this because nothing works like Vaseline lip products do for my dry lips. My tip is to lay a very nice nutritious oil down on my lips, like marula or maracuja (or whatever you like) and then cover with a Vaseline lip product or just Vaseline. Dry lips be gone!!
