Review (5/5): works well for me
I was a little bit concerned since some reviewers mentioned this vit c is oily. I thought it would feel too heavy for my skin but thankfully that wasnot the case.
Compared with any other Vitamin C serum I have used during the past 7 years, this is the thickest version I have seen. Usually Vit C is thin almost like water but this variety by MD is oil based. It works great for my skin giving it a bit extra hydration it needs. I use at night, I do believe it would be too heavy for daytime use as humidity is high. It makes my skin softer and feeling more hydrated then usual.
