not any stronger than others not accurate image [SEP] it does not feel any stronger than others plus it is 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
