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.
