Review (2/5): NOT any stronger than others, NOT accurate image!
It does not feel any stronger than others, plus it's a tricky advertisement: item is shown here with the pump/spray, but arrives as a regular bottle (with cup/lead -- see actual picture) & separate pump/spray which is so cheaply made, very uncomfortable, leaves a lot of serum on the bottle bottom without any use unless you open the bottle. NOT RECOMMENDED! There are a lot much better vitamin C serums here with great air-tight pumps, even cheaper & stronger than this one!
