It's been a few months I use this now and I still have half of the bottle to use! One pump is enough for your skin! I use it after my toner because I'm a bit afraid the toner will wash out all the serum and it works just as good :)

I have a combination/ acne prone and sensitive skin. I was afraid that my face wouldn't be oily enough to make it works but this product fit perfectly! My whiteheads were fewer and I'm pretty sure i will purchase it again when mine will be empty!

It's not a miracle product but a good one for a first serum that's why I don't give 5 out of 5 ;)
