Chap stick lives in my handbag as I use this one when out and about as its quick, easy and helps my lips feel hydrated when they need it.
I find some of the flavored ones a bit too strong so just go for the plain ones. Works well over top of some lipsticks too.
This product is another one of my trusty favourites that I always carry in my handbag. I like the blue chapstick with the white label. I like it because it smells like new baby/vanilla scent and it leaves my lips feeling hydrated and conditioned and lasts quite a while, where other lip balms dry out quickly and you have to re-apply. I like the white colour too because I can get my sons to use it on their wind burned lips and they won't refuse because it's pink. I'm not a huge fan of the black packaged one with the strawberry scented stick as it burns my lips and that is unpleasant when your lips are already cracked.
