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.

What is an undertone?

An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:

Pink/Cool

I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.

Neutral

I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.

Yellow/Warm

I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Reviews

Great Product Overall

"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)

Feels great, but pills

"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

"Good stuff"

Catherine A. (5/5)

Morning ritual

"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)

Texture Game-Changer

"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)

Does not absorb to the skin and causing irritation

"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)

Love this product!

"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)

I like it

"Packaging of the products is elite Wish the refills were larger though Seems you will run out fast"

Rebecca S. (5/5)

Sticky and caused breakouts

"I was really excited to try this product after reading reviews, but unfortunately it did not work for me. It dries sticky on the face and leaves behind a residue so when you put on makeup afterwards, it looks like glue is coming off your face. It also caused me to break out, which I typically don’t have issues with products at all. Will not be purchasing and will try to return!"
