    Anyone that has tried this serum knows the amazing glow it gives right away. I really love how it makes my skin look and feel. I use this instead of sunscreen which always gave me dermatitis and acne :((. This C Serum is just incredible!

    Best serum! It sinks into the skin so quickly leaving it glowing. I put it right before the sunscreen so it absorbs deeply and reduces my sun spots.

    This and the Retinoid Serum are the best things I have done for my skin ever! I only use clean skin care and thanks to NuVsio my skin looks better than it did in my 20โ€™s!! This Vitamin C Serum smells incredible (like fresh strawberries maybe) I noticed how my skin looks brighter every time I use it. Please never stop making it!!

  7. Beatrice

    One of my favorite serums! I had no idea this is oil-based. It just absorbs so quickly and I get that instant glow. My skin looks so photoshopped when I mix it with the balm concentrate. LOVE LOVE LOVE

    This serum feels so nice to put on! My skin definitely looks glowy. I’ve only been using it a week or so but excited to see how my skin improves over time. Mine arrived in the mail with a bit of a leak and the Nuvsio team corrected the situation super fast. Really impressed with the customer service! Thank you!

    Can’t say enough about this serum. My skin is instantly glowy and radiant!

  10. Barry S.

    I never tried a lipid-based vitamin C until this one, it is so nice and really absorbs quickly into the skin. Afterwards the skin is really glowy and dewy. Very nice finish.

    The Vitamin C Serum IS a game changer!!! Iโ€™ve always had dry and very sensitive skin, that gets even worse during colder months (freezing cold outside/hot dry air inside combination is not my skinโ€™s favorite). I am so excited that I have discovered Vitamin C Serum!!! It is the love from the first use and forever! My skin has never been happier! Highly recommend!!!
