I am very happy with this serum. With so many on the market its hard to find one that works. Definitely see a difference in my skin by using it at morning and at night after cleansing and before moisturizing. Things I like about this serum-

*Comes in a glass bottle with a pump top
*A little goes a long way!
*Texture is very light and glides easily on the skin
*Very light pleasant citrus smell
*Tightens in a good way. Not in the 'bar soap' extreme tightening way
*Visible results
