This is the Charcoal Lasting Base, shade 550. I purchased this from another seller, who used it three times. I have used it twice. I believe there is about 80% remaining. It was purchased in June of this year, so it's relatively new. It's a popular product, and I wanted to try it, but it didn't quite suit my skin type, so I'm selling it. It's a gentle makeup base that enhances the lasting power of your makeup. Thank you for your interest. - Brand: Chacott - Product Name: LASTING BASE - Color: 550 - Made in Japan
