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.

OSEA
Inspired by her grandmother’s lifelong love of the sea, Jenefer Palmer set out to share her passion through a plant-based skin care line infused with elements of the ocean. Distraught by the harmful chemicals she found in other products, Palmer resolved to craft her formulas with safer, nourishing ingredients.
While OSEA has now expanded into a world-renowned skin care line, their commitment has stayed the same—producing effective, wholesome products as pure as the ocean itself.
