It was too harsh for my skin and it is oil based. My atopic skin flared up…
If you have sensitive skin, I would suggest testing it before and introducing it slowly (what I did). But if you have really reactive and sensitive skin like mine, you should probably find a water based vitamin C.

I didn't like the consistency of this serum at all.
It felt like I was putting oil to my face, but since I always use the whole product to see results this did nothing to me other than feeling uncomfortable.

Cured my acne scars
I had mix feelings when I first bought this as I read that the smell can be off-putting. But I am glad I bought it. My acne scars faded a lot more after 3 days of using it and saw great results in one week. It also didn't break me out despite containing alcohols and oils. It does sting a little on the first application but doesn't irritate my skin. The smell can be quite strong Show more
