    So I never write reviews however this product most definitely deserves one! I have been following dr Kay on Instagram and have listened to her podcasts for a while now. Her work is amazing and her advice and tips on her podcast are so informative! So I decided to try some products from her line ( perfecting polish, day cream and this vitamin C serum) and I absolutely love everything! This one in particular I feel has made such a difference in my skins appearance and texture. My skin is smoother brighter and Firmer! I also have noticed I don’t get any type of breakouts like I normally would here in there Which is a bonus! I also just received my second purchase of deep blue hydration serum and the diamond line refine yesterday and I’m super excited to start adding them in my routine! Highly recommend these products! Thank you dr Kay!

    I absolutely love this serum! The combination of the Glycolic Acid Cleanser, Deep Blue Hydration, Brightening Pads and this serum has made my skin smoother and brighter. Can’t wait to try the other products!

    I usually don’t review products, but Dr. Kay’s skincare line is exquisite, effective and comes with the right price point to maintain. I have been getting many compliments at work and events on how youthful and glowy my skin is. I have been recommending to everyone that has been commenting on my skin.

    i’m using vitamin C serum since 2 years ago and i’m in love with it. My skin feels tight, bright, and the size of my pores get smaller!
    Thank you Dr Kay❤️

    I have been using this serum and I can tell a difference in my skin! I have seen a reduction in my fine lines and my skin seems bouncy! Plump! Looking forward to trying more of the Dr. Kay Beauty Skincare products!

    Love this serum and have been using it for over a year now. I seriously can’t live without this in my daily skin care routine. My skin has improved so much since I started using her products.
