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

Skin Has Not Made Any Progress

"I purchased this with the hope that I would notice changes in my skin’s appearance. However, it has been weeks, and I’ve seen no progress. It’s very expensive for the size and amount you receive. At this point, I’m only using it so my money doesn’t go to waste. It already feels like a waste because the product seems pointless in my routine. To top it off, my skin broke out more!"

Jessica L. (1/5)

Great first Retinal Use

"I am new to using Retinal / Retinol products and wanted to start with something clean and easy. Couldn't be happier with this product so far. It is gentle on my sensitive skin and a great introduction to Retinal products"

Emma F. (5/5)

gentle AND effective

"I am in love with this retinol so far!! it's been 3, maybe 4 weeks and it's already helped my skin. I definitely had some purging right away - I was also right about to start my cycle so the two working together did me no favors lol. BUT now on the other side of that my skin is smoothing out, it's looking more fresh in the mornings, not breaking out and it ISN'T DRYING. amazing! definitely recommend."

Elizabeth P. (5/5)

Gentle but Effective

"Use this on a nighttime 3-day skin-care cycling routine. It’s gentle but effective. Spreads easily. Absorbs quickly. Smells nice. Effective. Works on both my normal skin and my husband’s sensitive & oily skin."

Taylor K. (5/5)

The perfect potion.

"I’m in my late 40s with a history of hormonal acne and melasma. Very gentle, so effective, and great texture. Glass bottle is a nice touch. Added it to my subscription list."
