The BEST product out there is Dr. Hauschka's lip balm. I am a product junkie and this is the only product I am 100% loyal to. It is a bit pricey at $13-16 per lip stick tube, but, the product lasts a long time. It is 100% natural and doesn't contain harsh chemicals, so a little goes a long way. I have turned all my friends and family onto this product and they have become obsessed with it, too (but I have to give credit to Jennifer Aniston and Brad Pitt--I read an article years ago in which they were interviewed and said they both couldn't live without this product; I was curious and bought it, and now I understand why).

Also, the reason you are likely getting blisters and drier lips is that most lip balms contain harsh chemicals and exfoliants that ironically dry out your lips and make you want to apply more chapstick on them. In turn, your lips become thinner and less able to protect against the elements. It's a vicious cycle!

I promise you that once you use Dr. Hauschka, that vicious cycle will decrease or stop.

Good luck!
