Ultimate Antioxidant Boost Vitamin C Serum


"This is the product that convinced me to launch Youth Corridor. It’s an unbeatable combination of Vitamin C (L-Ascorbic Acid), Vitamin E and Melatonin- all antioxidants. When paired together, they offer the ultimate treatment to stimulate collagen growth, reverse existing sun damage and even prevent future sun damage.”

~ Dr. Imber

  • L-Ascorbic Acid is proven to protect skin from oxidation that causes skin cells to break down. 
  • The combination of L-Ascorbic Acid, Vitamin E and Melatonin protects skin from environmental damage, enhances skin’s repair process, reduces inflammation, fine lines, and irregularities.
  • Propriety MicroSperse® Dispersion Technology eliminates the traditional harsh, potentially irritating emulsifiers and surfactants, to deliver benefits while not damaging the skin’s lipid barrier.
  • Product is Paraben- and Surfactant-free.
  • Size: 30mL | 1 fl Oz

Best Vitamin C serum

I’m on my second bottle and I absolutely love it. The consistency is one of my favorite parts and how it makes my skin glow. It also sits beautifully under make up! Will definitely purchase again!


I have been using this amazing product for three and a half years now. I apply it EVERY morning under my sunscreen, regardless if I am staying home or venturing out. I frequently receive compliments on the smooth and wrinkle-free condition of my skin which I greatly appreciate given my age. I will be 65 this December and I believe that the Ultimate Antioxidant Boost Vitamin C Serum is the reason my skin looks so young. I cannot imagine starting my day without it.

Thank you for sharing your review and for being a longtime client!

It’s a great product plus it’s unscented ! I’m thrilled there’s no scent !

Elizabeth Cassata
Best Serum for Sensitive Skin

I was skeptical to try this serum as I have very sensitive skin, but I have been using this serum for over a month and have had no reactions. Even better, my skin feels more youthful and radiant! I highly recommend this product, worth every penny.

Part of my daily and nightly routine

I LOVE this product. As someone who is always skeptical and this being on the pricer side, I went in with low expectations. But after using consistently (day and night) for about 3 weeks people started asking me "what I'm doing to my skin." Honestly, nothing had changed in my routine except for this addition. Cannot recommend it enough. It definitely has made my overall tone more even and less blotchy and I find myself not feeling self conscious if I don't wear foundation.
