I've been using the lip mask for several years now.
I've really seen great improvement in appearance and how smooth they feel.
I love how it is soothing and not an overpowering product that must be used every day. I have used products that if I didn't use it, my lips were dry and cracking. This is a delightful "caress" of moisture and lubrication, I find it wonderfully weightless and inert.
