This is my 3rd purchase, and i wear this all the time. I use it mainly for the spf. I use a small pump and it's enough (because if like me, you stick to your routine, your skin will improve DRASTICALLY). When i get breakouts or i am tired, i put a little bit more for extra coverage. I used to carry around in my purse for touch ups but i NEVER need to touch it up. This is going in my fridge for safe keeping until i use it !! Thanks for the amazing sale Style Korean, i got this for 4$ !!!!
