Yaman Wrinkle Beauty Pro Gold. I'm not sure when it was opened, but I've been using it without any problems until today. I will clean it with a disinfecting wet wipe before shipping, but please understand that this is a home-stored, second-hand item before purchasing. This is a makeup base to make wrinkles less noticeable. Using it as a makeup base improves the hold of your makeup. It has the characteristic of spreading smoothly on the skin and fitting firmly.
