Does marshmallow vanishing cream show good results in getting rid of acne scars without being greasy?

I hate using creme on my face in summers, as I have oily skin. I normally use Neutrogena face wash to clean my face, and then apply some powder foundation on face, to camouflage the acne scars marks on my face. Nonetheless, I have heard about marshmallow vanishing cream, and I was wondering if it could help me get rid of my acne scars with regular use. I would like to know from some skin expert whether marshmallow vanishing cream is effective, without really being greasy on face in summers, as I usually don’t use any crème on my face in summers! Please advice aptly! Thanks.
