Excellent product.

Rebecca Earlewine

I have been using this product for years every morning after shower pre moisturizer/make-up and every night after washing my face. I absolutely feel it has made an improvement with how my skin looks and feels as well as the occasional break out seems to have gone away. I also get frequent compliments on my skin looking far younger than my age. I have tried other Vitamin C and age defying serums out of curiosity and always come back to this one.


I use this product daily and it has made a big improvement in my skin. Can’t live without it!


The Vitamin C is Liquid Gold. Has made a huge difference. The lifelong bags under my eyes are truly getting better. I can’t believe it. Thank you for recommending it for me!


The RXSystems Vitamin C serum is an excellent product. I put it on at night and the next morning, my face has a certain glow about it. The serum also helps me fight against acne, which I have never had in my life, and now (at the age of 60), I seem to have acquired. It is usually gone overnight or by the next day, I use the Vitamin C. It was a bit expensive, but I think it is worth it.
