It works!! Worth every penny!
I'm a type 2 diabetic and insulin resistant, so I normally have a dark ring on the back of my neck. I've tried everything. This stuff with the first treatment removed it. It's gone! Worth every penny!! The before photo is a year old. However it looked like that prior to the treatment.

Amazing product
Size: 2.12 Ounce (Pack of 1)
This cream is amazing! I was not expecting the results I got. My face feels soft, plump, and the redness in my cheeks is disappearing. My skin looks youthful and I’m 57. Very hydrated definitely don’t hesitate to purchase.
