Key Ingredients

  • Gigartina Seaweed (Gigartina Skottsbergii) A red algae rich in polysaccharides, vitamins and minerals such as potassium, magnesium, iron and calcium. Deeply hydrates and helps provide collagen protection benefits by forming a barrier on skin. Optimal anti-aging benefits.
  • Undaria Seaweed (Undaria Pinnatifida) A brown marine algae rich in iodine, iron, potassium, calcium and vitamins B1, B2, B3, B6 and B12. Composed of bioactive molecules known as Fucoidan, which play a unique role in maintaining skin. Reduces appearance of fine lines and wrinkles while minimizing surface redness.
  • Macrocystis Seaweed (Macrocystis Pyrifera) A bioactive brown algae abundant in vitamins, minerals, antioxidants and essential fatty acids. Decongests pores and visibly diminishes uneven skin texture. Plumps skin with anti-aging benefits and reduces surface redness.
  • Hyaluronic Acid A plant-derived polysaccharide found naturally in skin that holds water. This hydrophilic (water-loving) molecule delivers moisture without clogging pores. Instantly plumps fine lines and makes skin glow. Ideal for all skin types.
  • Sodium HyaluronateA vegan ferment of Hyaluronic Acid. This water soluble salt is a smaller molecular size than Hyaluronic Acid. Helps restore skin’s moisture barrier.

I cannot rave enough

I NEVER write reviews but felt compelled to endorse this product because it is just that great. I have super sensitive skin and most products on the market are too heavy, too scented, too aggravating. Within a few days of using this serum my skin felt dewy and fresh and so hydrated. I will never be without it again!!!

Evens out skin tone

Use this at night & follow up with the atmosphere protection cream. I have very reactive skin, I had 0 issues with this product. It evened out my skin tone ( especially my t-zone) like no other. You have to be careful - a little goes along way! Too much can dry you out( at least for me). I’ve been using Osea for 4 months now, I’ll never buy anything else! My skin looks so good, I don’t feel like I need makeup anymore.

LIFE CHANGER

I am a 24 year old with intense adult acne and this serum has been an absolute life saver. I can instantly feel it deep in my pores and feel like I am at the spa when using this product in my own bathroom. I highly recommend this to everyone!

More than I expected , Amaizing

I lived in California Orange County for 13y and first time I saw this brand was at a high end spa , turn out that after years was so happy to find it now at Ulta . Love this serum , I have combination skin and after only few days of using it ,my skin looks back “alive”,my pores got smaller and overall my skin feels tight , like I just got out of a facial. By far is one of my favorite .
