This is my second bottleI am a pharmacist studying abroad and this thing works amazingly and if you want a better results use derma roller before it.I like the price compared with the money

It is great product for skin FIRMING. Need to try in a gentle way until skin will get use to it. I like it is not sticky. And was completely absorbed by my combinational skin

This is a superior Vitamin C serum! I use it on my face...arms...and legs. I can see the difference. It is much better then other Vitamin C products I have used. Just purchased my second bottle.

I was so excited about this product and was hoping this would help feded my acne dark spots but this ended up make me break out even more. The color was clear but after open a bottle for a week, it changed to slightly yellow. Very disappointed

The customer service team helped me to find the correct formula for my skin type. I'm pretty sure this serum works even though is not appropriate for me.

I use this right after washing my face but it stings a little if you don't wait a minute before applying. My face feels smooth. even before I apply moisturizer

Tried if for several months to test some areas and no noticeable changes or lightening.I know there are other product that actually works. Unfortunately, perhaps a bad batch...

I love this stuff! I am 32 and this definitely softens my forehead wrinkles and the ones around my eyes and lips. Works like a charm. Need a dermaroller to help with absorbing but otherwise works wonders.

Made my face brighter and clearer. I now use hyaluronic acid serum which is a lot more effective in a sense that it has not only brightened and cleared my face but also allowed my face to absorb more moisture - especially living here in CA.

This is easy to apply, no sticky feeling afterwards.I started using this the first night I got it, this is a game changer for my skin. My skin's texture is smooth and I have a glow and my face is soft to touch.
