Details & care

What it is: A bioactive serum that targets all signs of aging and supports skin's own moisture barrier.

Who it's for: Ideal for all skin types, except sensitive skin.

What it does: Target all signs of aging and support skin’s moisture barrier with one, powerful serum. Achieve a brighter complexion with this seaweed-enriched formula containing vitamin C, niacinamide, ceramides and natural peptides. It helps improve the look of skin elasticity, firmness and fine lines for more youthful-looking skin. Dermatologist tested and essential oil free.

Key ingredients:
- Vitamin C derivative (3-o-ethyl ascorbic acid): a stable form of vitamin C that helps improve skin radiance
- Niacinamide (vitamin B3): helps reduce the appearance of fine lines and wrinkles and smoothes skin
- Natural peptides: two natural plant-based peptides, derived from peas and sacha inchi, help create a more even complexion delivering smoother, firmer, younger-looking skin
- Ceramides (oat kernel extract): a complex of skin-identical lipids including ceramides supports the skin’s own moisture barrier
- Laminaria saccharina seaweed: sustainably sourced seaweed from the coast of France, rich in potassium, magnesium, calcium and iron

Research results:
In a consumer study on 32 women ages 37 to 65 over four weeks:
- 94% said skin looked smoother & softer
- 88% said the look of lines & wrinkles improved

How to use: Apply 1–2 pumps of the serum to clean, dry face and neck. Allow to absorb. Use in the morning and at night.

Since using this product over the last 2 years I can see improvements in my skin. I have less dark spots and my complexation is brighter.

Naked without it!

Hello - I'm truly disappointed the anti-aging sea serum has been discontinued. In general, I am a minimalist when it comes to using cleansers, lotions, toners, etc. However, this Osea product has become my morning staple combined with the hyaluronic serum. My face feels and looks brighter after use. Please let me know when it will be coming back. Thank you!

Best C Serum EVER

I've tried so many of these from other brands, and nothing worked for my skin. This stuff is a dream. My skin looks so bright and smooth. I couldn't be happier!

Love this!

This is my OG love from Osea. I’ve been using the serum for about 6 months and the difference in my complexion is visible. Fewer lines and evening of texture. I am a fan for life.
