Bright Skin
This Vitamin C has brightened up my skin. I also love that it's fresh every time you use it, and doesn't smell disgusting like other C serums can (it literally smells like roses, which is where it's derived from). I highly recommend!

Best Vitamin C
This is the best vitamin C serum I’ve tried. I’ve tried quite a few but this is the first one that actually got rid of some old acne scars and made a very visible difference in my skin. I’ve even received compliments on how great my skin looks. I know it can be messy in powder form but here is what you need to do: with the lid on put it upside down and gently tap it on the counter, then tip it right side up and carefully take the lid off. Next put one hand just below the counter top and tip the bottle on its side and tap the side of the bottle on the counter to knock out a little powder into your hand. Then spray the Holi Water onto the powder in your hand and mix. With this system it works great.
