The only thing I have found not so great with this serum is it leaves my skin greasy. 

This is a potent serum, rich in vitamin C, that brightens and rejuvenates skin, tackling dark spots and promoting a radiant complexion with its lightweight formula. I have used this a few days in a row and it seems ok. It is definitely something you would have to use consistently for a period of time to see results in my opinion. It did leave my skin a little greasy. I am not a fan of that. Because of that it is something I will only use at night. Because it has a strong dose of vitamin C in this serum, if you have sensitive skin I would suggest mixing a drop or two with your moisturizer. However, I have sensitive skin and I haven’t had any issues.
