I use it right after I wash my face, and eventhough my skin type is oily type, sometimes right after I wash my face, my skin feels dry and when I use this serum, my skin feels very moist and hydrated. So far it is also suitable for my oily skin type.

None so far.

Although its name is serum, but this product is used right after cleansing your face (cleansing) and before toner.
