This is liquid gold! I have combination skin while also fighting fine lines . This serum soaks in immediately and I compliment it with the Undaria Argan Oil this equals perfection of glowing dewey skin. I highly recommend.

I use this sea serum daily with my hyaluronic serum. Perfect after a long beach day to treat dehydrated skin as well as daily use.

I’ve used the Osea products for years, I use the blemish balm and the algae oil daily !!!!! But I just tried this for the first time! I put it on and the blemish balm after. I think my skin feels great and I love the way it feels. It soaks in and hydrates and my skin just feels great, I think the price is high considering the bottle is so small but non the less I love it and I love their products :)

The website states that the vitamin sea serum is fragrance-free, however, it does have a mild scent upon application that fades within a few minutes. I found that one full pump was sufficient to cover my entire face, ears, front and back of the neck, and decolletage. The product gave my skin a nice glow. However, I do not think that it lived up to moisturizing my skin. As previously stated, I did not use an OSEA Malibu brand moisturizer cream during this testing. Nevertheless, I have used other serums that provide both brightening and moisturizing effects. After three days of only using OSEA Malibu, my skin felt very dehydrated and I decided to incorporate these products in addition to my regular skincare routine. The website does state to follow with a moisturizer, but I would prefer to use a serum that has double-duty. The OSEA Malibu essential hydrating oil most likely would have been a good addition to this routine.

I find that algae serums agree with my skin. I thought the aging process might make it a touch strong for my sensitive skin but it didn’t. The serum does go on a bit tacky but once I apply my face cream it soaks in well and keeps my face well hydrated. I do find that I used the bottle in 30 days or so however it’s still a better value than what I have been using.

I LOVE this serum. I use it with OSEA's ocean cleansing mud, and it gives my skin a lovely and healthy glow. I live in Hawaii and am in constant fear of sun spots and early aging due to sun exposure, and I swear this serum protects my skin from sun damage. I do hate how expensive the product is, but I find myself coming back and buying it anyway. When I run out and don't buy more, I notice a difference in my skin: the glow is gone!! So it's expensive, but if you use about a half a pump it can last about a month. I love it so much I use it morning and night. I think it's definitely worth the price, and this is another OSEA product I will use until I die.
