    Acne marks were noticeably reduced from the very first week. It has a slightly bad smell but it really does a great job!

  6. Danae (verified owner) -

    It is definitely better than the previous Vitamin C I used and it also offers hydration due to the Hyaluronic acid.

    The best Vitamin C serum we have tried in less than 2 weeks of use my face is noticeably brighter and the acne marks on my daughter's face have started to subside. You absorb very easily.
