Why we stand behind it

High-performance 9% AHA + 2% Phytic Acid treatment exfoliates to promote skin turnover, which evens tone and texture overnight. Nutrient-rich seaweed and Shiunko oil reinforce skin’s moisture barrier to reveal radiance. Wake up to clearer pores and a smoother, brighter complexion.

Immediately after 1 use*:
97% agreed helped reveal smoother feeling skin

After 2 weeks*:
97% agreed skin felt softer and smoother
94% agreed it smoothed the look of pores
94% agreed skin looked healthy
91% agreed skin looked glowing

After 4 weeks*:
97% agreed skin felt re-texturized
94% agreed skin felt and looked transformed
87% agreed skin looked more even

*Based on a third-party consumer perception study conducted over 4 weeks on 32 women ages 37-65.

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:


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.


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.


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.

Apply on clean, dry skin before bed.
For added hydration or for those with more sensitive skin, follow with a moisturizer.
Cleanse in the morning, then follow with your regular AM routine and always apply sunscreen.
Use 1-2 times a week or as needed.


Seaglow Resurfacing Scrub and Seaglow Overnight Serum should not be used together, instead use on alternative days as to not over exfoliate skin.

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.
