I have used this product for several years. It keeps lips moist and smooth. I use it at night and the next morning there is enough left on my lips to help my lipstick cling. I'm in my 60s. This doesn't sting and does not cause instant plumping. Rather, it maintains a healthy and young appearance. Although expensive, a tube lasts for months

In terms of plumping the lips immediately in the moment, this is not what you want. However, if you want healthy skin on your lips and to maximize what you already have, this is amazing. It is pricey, so I only purchase this once in a blue moon and use it only before bed until it’s gone, but every couple of years, when I’m wanting to revitalize the little some’ some’ I was blessed with, this is my go to. It works overtime, so don’t expect it to make your lips look like they got stuck in a pool drain, but it will add a life back into them.
