This is the first time I have ever spent so much on a lip balm, especially since nothing works on my chapped lips. And what drove me to do so I have no idea, but grateful that I did. I’m in my upper 40’s and have had chapped peeling lips for as long as I can possibly remember and even as a child. From the first time I used the lip serum, my lips found relief. After about a week my lips quit peeling. As far as plumping goes, I cannot say that I noticed any sort. But, I can say that I am impressed by the relief this serum has provided to the chapped lips that I have suffered with my entire life.
