Love it!

My skin has become super sensitive and I tried the OSEA line and absolutely love it. The Sea Serum goes on easily and only a tiny bit is needed. It feels great on it's own, but I use the Advanced cream with it.

The best!

As a master esthetician, I’ve tried sooooo many Hyaluronic Acid serums. This is my favorite because it’s clean and non toxic and also gives such great hydration results! My skin feels plumper and more moisturized just after a few uses. This will be a staple in my skincare routine!

I really like this serum! I’ve noticed a difference in my skins overall texture since using this. I layer the advanced protection cream to help with my winter dry skin!

Moist and Dewy Look

I received this as part of the BF promo. I have used it a couple of times - in Tokyo and on my recent long flights. I’ve to say that it kept my face moist and dewy (flight was 14 hours from East Coast to Tokyo). I like the moisturizing effect without my face feeling too oily. In addition, I sleep with an air conditioner in Singapore now (on a holiday) so this is perfect.

LOVE this product!!

I recently purchased a few items from OSEA and am loving all of them! This product in particular has helped with my dry skin that I get every winter. It's very light weight and doesn't cause any breakouts. Since using these products, my skin has looked healthier than it has in a long time! THANK YOU OSEA!

Moisture magnet

Love this serum. I get seasonal dryness that in the past, I over moisturize and then will get breakouts due to my combination skin. This serum is perfect, my face is moisturized and clear and I’ve gotten so many compliments on my skin since I started using! I will be reordering and trying other products. Don’t let the price scare you-a couple of drops will cover your face and neck so this bottle will last and allow me to get every pennies worth!
