Why we stand behind it
Normally, Retinol degrades and oxidizes when coming into contact with light, air, or water but this clinical-grade serum is activated fresh for peak potency.
Powderized Retinol is precisely dosed with 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 0.25% pure Retinol (equivalent to a starting prescription Retinoid), subjects screened for sensitive skin had no irritation using the serum every evening with excellent results:
- 97% of subjects had a decrease in fine lines and wrinkles in 1 week.
- 96% of subjects had an increase in firmness in 4 weeks.
- 76% of subjects had an increase in textural smoothness and elasticity in 4 weeks.
*Based on a clinical testing study with measured instrumentation of 29 subjects evaluated with a Visia Image Analysis Pro over 4 weeks.
Key ingredients
Retinol: a type of Vitamin A that stimulates cell turnover so you shed dead cells and build collagen faster to reduce fine lines and wrinkles and bust blemishes.
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.

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.
