I love Some By Mi, but their regular serum was the only product I'd been dissatisfied with till now, it was too oily for my combo skin and made my whole face look and feel greasy, plus it took ages to sink in.. So I decided to just skip the serum altogether, until I found this. When I first used it, I immediately loved it! It's not oily at all, it feels very liquidy, almost gel-like, like a thicker version of their toner. Very spreadable and sinks in almost immediately with no stickiness whatsoever! It almost feels like I didn't put on another layer! THANK YOU SOME BY MI for listening to buyers and offering a solution!!!
