I have used it for nearly 13 years and still think it's the best. The serum texture is just right, not too sticky and not too thin. It's been selling out every month for 13 years that I've been selling it.

Use it every day!
I have been using the Asteroid Vitamin C serum for years, and at 65 have the skin of someone decades younger. I will continue to use it until they stop selling it!
