Best vitamin c serum on the market

I have tried countless vitamin c products and I keep coming back to skinceuticals CE ferulic! It’s a classic for a reason! It’s not sticky, or oily (which I’ve found others to be) and most importantly, it does the job! I’ve learnt to not waste my money on other brands when none will live up to this one. It brightens my skin and helped treat stubborn pigmentation I managed to get in pregnancy. Can’t recommend it enough!
