I apply it only in the night. The serum is pretty greasy and doesn’t get fully absorbed into the skin - leaves a super oily finish. Upon application of the corrector, it becomes even more oily!
In the morning, I do notice reduction in marks and the skin is still greasy after the night as well. Reduced greasiness though. However, after washing my face, I feel like the top layer of the skin has a very artificial plastic like feel as though it will peel off. If no moisturiser is applied, it feels really dry and tightened.

I will say that marks have reduced in a week. But I feel the active ingredients added are quite a few and give a slight burning/tingling sensation when applied. Due to this burning feel and the excess oiliness, I reduced usage to just once a day.
It is helping, curious if all marks will disappear!

They reduced acne marks significantly in a week. Good one.
