I bought this for travelling purposes to save some space and saving bringing a serum, I have to say it does the job for a very reasonable price and I guess vit C is preserved in a much better way.

Very nice product to mix in with your body cream!

The spots on my face and unevenness has gone with continuous usage. I use it atleast 3 times per week mixed with my moisturiser. This has brought a significant brightness to my face. 

Very potent as you can feel some slight stinging. Liquid Vitamin Cs decrease potency once the bottle opens. Easier to mix with thinner moisturisers.

Great product! Perfect as a boost of pure vitamin C to your mask or cream.
