I have used this product for 5 years now and I truly love it. It has evened out my skin and minimizes my hyperpigmentations. My skin still looks fairly youthful at the age of 45. It’s a definite must in my morning and night skin routine.

I have tried many brands of vitamin C since it is an important step to optimize healthy skin. Dr Louie’s is the best- it seems much fresher and my skin feels/ looks great when using it!

I have been using this for about a week now. I'm already starting to see a difference. I could not say enough about this product. Especially because it's EWG approved.

This c serum really seems to help my skin. Buying again

Before using Vitamin C serum I felt the skin dried even after moisturizer. It had an uneven colour. First impression was it was hard to control the flow, was not expecting the contents to be quite so liquid. How if felt on the skin was tingly yet not drying. But I liked how the skin reacted, almost like the hair products, tingly, and fresh. After using Vitamin C Serum, when I look at the photos my skin has a vibrancy, more even and looks less dry and wrinkles are calmer.
