Why we stand behind it
Normally, antioxidants like Vitamin C degrade and oxidize when coming into contact with light, air, or water but this clinical-grade serum is activated fresh for peak potency.
Powderized pure Vitamin C is precisely dosed by a patented precision dispenser and seamlessly activated in your palm with a hyper-moisturizing Hyaluronic Acid. The result? A serum that delivers visible results in 1-2 weeks without irritation.
In clinical testing on this 10% pure Vitamin C (L-Ascorbic Acid), subjects screened for sensitive skin saw no irritation with excellent results:
- 100% of subjects had a decrease in fine lines and wrinkles in 1 week.
- 86% of subjects had an increase in firmness in 4 weeks.
- 66% of subjects had a decrease in discoloration and pigmentation and an increase in brightness and radiance in 4 weeks.
*Based on a clinical testing study with measured instrumentation of 28 subjects evaluated with a Visia Image Analysis Pro over 4 weeks.
Key ingredients
L-Ascorbic Acid: the pure form of Vitamin C, is an antioxidant that wards off oxidative stress and free radicals while promoting collagen production-- both preventing and reversing fine lines and wrinkles, sunspots, and discoloration for a brighter, more radiant complexion.
Hyaluronic Acid: this multi-weight formula penetrates multiple layers of skin to deeply hydrate, boost elasticity, plump and restore the skin from within, helping to smooth fine lines and wrinkles.

"Love the product. My skin seems much brighter. With that said if you do not make an considerable effort to rub in this product you will wake up with orange streaks/clumps. I made sure to apply with care last night and did not wake up this morning like a pumpkin."
— Lisa S. (4/5)
"The two part system is pretty easy to use, and the serum feels pretty luxurious on the skin! Downside is it pills if you don't let it dry on your skin for an hour or more (which is tough for quick mornings getting out the door). Also it's been out of stock for some time which it a bummer!"
— Erin S. (3/5)
"Good stuff"
— Catherine A. (5/5)
"I love using the vitamin C in the morning. My skin is looking more even and brighter, and it just feels light and fresh as I put it on my skin. I'll keep using to help even out dark spots, and it feels great under sunscreen!"
— Chloe Y. (5/5)
"I have used this system daily now for the past month. I noticed a change within days. . . but the real miracle is that my husband noticed TOO! This is my forever Vit C."
— Kathryn B. (5/5)
"like the product so far but the packaging upon initially opening can spill a lot of the product."
— Leah D. (3/5)
"Unfortunately, didn't work for me. Causing extreme redness after application, and does not absorb, stays on top, and caking. I feel like it is better if I just mix powder with Rose water, but it is still causing the irritation"
— Maryna (2/5)
"I've been using for about a week now and I love the way that my skin feels after application. I've had noticeable improvement in firmness since I've been using it."
— Shelly M. (5/5)
"Packaging of the products is elite Wish the refills were larger though Seems you will run out fast"
— Rebecca S. (5/5)
