Chapstick is definitely the classic, so much so that it's become the generic term for lipbalm for many people.
I wouldn't say it's the greatest but it does a fair job. It's not as intensive in moisture as I like but it's not drying like some balms can be.
This is the balm I buy when I'm inexplicably without one on route to the beach or a hike as it's sold everywhere reasonably cheaply. This is where the spf factor comes in handy.
Does the trick nothing extra amazing!! mositurising, non gritty like some.... all round good lip balm.Plenty of more nice smelling/looking lip balms out there.
