My new anti-aging pal

I really like this hyaluronic sea serum. It makes my skin feel smooth, refreshed, and hydrated. A little goes a long way, so it's a great option if you're not looking to spend as much as some of the other serums. I use it AM and PM and love these results!

Great Serum!

I have reordered Osea Hyaluronic Sea Serum because I'm visibly noticing how much smoother and younger looking my skin is after using the serum for a couple of months. I'm really happy with the sheen and overall health of my skin, and the only thing I've changed in my routine is applying this serum nightly.

Osea Hyaluronic sea serun

Nice! It’s not as good for gua sha as I had hoped. It gets a little sticky at the end…. I find face oil works better.

I was excepting more hydration

I love my other Osea products, so I had really high hopes for the hyaluronic serum. But maybe my expectations were too high? I’ve been using the product for about 3 weeks and I haven’t noticed a big difference in my skin. Perhaps the effects take longer to appear. Other hyaluronic acid serums I’ve tested plumped my skin up immediately after using, but this one doesn’t. I’m not swearing this product off, but I’m curious to see if and when the effects kick in.

Magic in a bottle

Magic! On its own this serum adds instant moisture. Paired with other creams, it boosts their benefits x 2.
