It's the sine qua non of lip balm.
I've used everything, from cheap Vaseline, to hard-to-get-in-the-UK Aquaphor, to high-end Clarins and Laura Mercier.
Nothing comes close to Lansinoh. I've healed my peeling cracked lips in a week or so using this and because it's got lanolin in it, it seems to sink in and create an inner barrier, unlike a parafin one.
I'm now back to my red-lipstick look (thank god as it only takes a minute in the mornings)
