This is a French miracle. It's intended for skin irritations, but can be used for pretty much anything on any body part. Dry skin around the nose and mouth, chapped lips, rashes, eczema - you name it, and this little tube will come to the rescue.
The closest comparison I can come up with for this would be Elizabeth Arden 8 Hour Cream or the Australian PawPaw ointment. But this is a bit thicker, and unlike 8 Hour Cream has a very subtle scent.
I heard abut this in Make-Up Artist Magazine - it was listed as a fave in the kit of one of their featured make-up artists. Upon further research, it turns out to be a lot of artists' and models' fave. Mainly used for severely chapped lips - not only does it help to heal them, but it seals down any flakiness and applies matte so it won't interfere with lipstick application.
Here's what it looks like:
I recently discovered that they also make a lip balm stick, so I'm going to give that a try and see how it stacks up and whether it's a bit easier to use.
The only down side that I can see is that it's really hard to get out of the tube because it's so thick. But once you get some out, a little goes a really long way and the tube is huge - and super cheap. So it's worth the work!
