We go through vaseline at home..I put it on my hands when I wear cotton gloves under my latex gloves to clean; Works great on the kids eczema and lips..oh yeah...morning and evening..
As mention..it smoothes out the lips and it makes the lips look so much plumper...It's a cheap miracle in the jar! LOL
Wow! I feel like an insider! I've been using vaseline on my lips for years. I put it on at night to keep my lips from drying and cracking, and use vaseline lip therapy throughout the day.
If you have really, really dry and/or cracked lips you might want to also try aquafour--it's nothing more than hydrogenated vaseline, but works much, much better on irritated skin than vaseline.
