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.

Amazing

I am really liking this serum. We live in Colorado so my skin tends to be extremely dry. This has helped a lot.

I never spend time writing reviews because I prefer reading them to make my decision, but I really had to write one about this product. I suffer from acne rosacea and oily skin and have been using organic products as much as I can for the last 1-2 years and that's helped me significantly, but I was looking to toss it up, so I splurged on this product. I use it typically at night before I put on my retinol, and then put a face oil on top of that after it sinks in. WOW. I thought I was moisturizing enough but clearly I was not. This serum is so light and absorbs in seconds on my face and has made a world of difference in my face. I glow all the time now and my redness has gone down. Sometimes I use this twice daily after I exfoliate with the Vitamin C polish from Osea 1-3 times a week just to lock in the hydration, and it does me wonders. I wish this wasn't so pricy because I'm almost halfway through mine after 1 month. You don't need to use a ton of this product on your face, but about one nicely sized drop will suffice if you use the plunger all the way. The pump/plunger on this is pretty irritating and hard to use, I wish it would just be a regular serum dropper instead.

Not good for my dry skin

The combination of dry winter weather and my naturally dry skin did not react well with this serum. After a month of intermittent use my forehead was flaking so bad that no matter how much moisturizer I used by the end of the day it was “snowing”. I tried all of the tips to hydrate my skin thoroughly before applying the serum and sealing it with a moisturizer but I think my skin is just too dry for this product. Unfortunately the flaky forehead lasted long after I discontinued use, but the probiotic polish and atmosphere protection cream seems to be correcting the issue. I passed the serum on to my mom but continue to love most of the osea products I’ve tried.

Hyaluronic sea serum

I will purchase this serum again. It is easily applied over damp skin. It has a lovely light fragrance, and absorbs well. I do feel my complexion is brighter after using it, and think there will be continued improvement the longer I use it.

Nice plumping benefit but stings my eyes

I don't usually invest in serums because I use a prescription retinol, but when this one went on sale I decided to give it a try since I'm always seeing beauty editors swear by hyaluronic acid. Of course as soon as I ordered it a big story come out about how it can actually be drying and irritating. I decided to see for myself and starting using the serum every night for the past couple of months. My skin is plump and hydrated when I wake up, but I haven't noticed any major changes. The problem for me is that my eyes sting like crazy and tear if I get the product within an inch of them, to the point where I can't even keep my eye cream on. My eyes are very sensitive so this isn't terribly surprising, but it's enough to keep me from purchasing again.

Love Osea!

I love Osea products! I am 46 and have struggled with skincare my whole life because I have super sensitive and dry skin. Osea products are soothing, don't irritate my skin and truly moisturize my skin. Also, the smell is subtitle and lovely. You have a super fan in me!
