Moisture? Yes Please!
I wanted to wait a few weeks after trying this serum before reviewing. I absolutely love it! I live in the northeast and dealing with a harsh winter causing my skin to be so dry. This is so moisturizing, leaving my skin so plump and soft. To be honest the scent isn’t super pleasant but I can get past it because it’s wonderful effectiveness. I feel like it has helped me with anti-aging and with anti-acne. It’s a no brainer! The only other thing is that I am going through it faster than I would have thought. I will definitely be repurchasing. I also really only want to use “clean” products. I use the app, Yuka, to check all my cosmetics. This one is definitely clean!

Amazing
This face moisturizer is great. I can even use it in high humidity. It will be even more phenominal in winter time.

Pair with their water cream and watch your skin hydration change overnight
This plus their water cream made me look 10 years younger within two days. I am not impressed easily, but the hydration maintenance on my skin was undeniable. I love the two combo, but the weird funky smell of the water cream makes me wonder. The exact same funky smell is what you smell when you wash your clothes in the summertime but then you leave them in the washing machine for too long. It's not super strong but it's enough to make you go what the heck?

Nice Serum/Terrible Smell
I love Osea products, but gave this one 4 stars - 1 taken off for "scent" - more like SMELL!! It smells like dirty socks. I do like the way it moisturizes my skin. The Osea night serum smells like lavender - I wonder why this one smells so nasty!

LOVE
I wish I would’ve taken a before and after photo. This product is amazing. My face stays hydrated all day. I travel to dry places and this lasts. I’m truly impressed with all Osea products that I’ve tried. It initially is lightly slimy when it goes on but absorbs and disappears quickly. I’ve seen such a difference in my skin quality.

Love this product line!
I started using Osea about a month ago after an expensive facial. I had been having a terrible problem with both breakouts and terrible dry peeling skin at the same time - even my eyelids were dry and peeling (weirdly the anesthetist told me my skin was oily). The cleansing milk, sea serum and water cream together have balanced and helped my skin heal. I started using the atmosphere protection cream under my powder mineral foundation (after water cream and I do my eye makeup first) and it has worked for me better than any primer, and probably better for my skin too.

Very disappointed
I have been buying this serum for a while. I just ordered and returned the last one. First I thought i got ordered some nock off ( the bottle was too small and looking a little bit different) Than I searched through my old order and realised that they changed the bottle and made it a lot smaller but kept the high price 🤦🏼♀️ Not cool. The serum is good but not enough to justify the money for very small quantity.
