I love this oil serum! I use this every night along with another serum I have for double the effects. It works great alone too, but for personal preference, I like to use it with my other one. This is an oil serum, so it leaves a dewy finish, and I would not recommend you to use it under makeup if you have oily/combination skin! This is why I only use it at night. It really leaves my skin nice and soft!
