    I have a section of my eyebrows that have thinned. This has brought them back!

    LOVE THIS PRODUCT!

    I have been using Obagi Eyebrow Boosting Serum for several years. My brows are fuller than ever and using this product has been a game changer for me. In the beginning, I was very diligent in my application and saw results within weeks. Now, years later with my brows established, it’s okay to miss a day once in a while without any changes. I don’t go away without it!

    Excellent Results

    I have been using this product for about 60 days and the results have been amazing. I can truly see the benefits of using this product. My eyebrows are growing in where I did not have growth before. I would highly recommend this product.

    After using two tubes of this serum, my eyebrows show considerable regrowth especially within the inner thirds of my brows. The outter thirds show moderate regrowth.
