Bests & Worsts Reviews from Amazon

This vitamin C serum, by Serumtologie, is rated one of the top among dermatologists - I did HOURS of research since there are actually Thousands of them out there, and Doctors rated: Stability, Percentage of vitamin C, PH levels, Oxidation, Water base or oil, Skin types, Colorants (don't get an orange one), Derivatives, Vitamin C Form, Packaging, price, etc. and it is simply Awesome. I don't have money to throw away so I let Dermatologists do the scientific part for me - take my word for it I do TONS of research, I've got the time! :)
