    Miracle in a Bottle

    I regret to inform you that this serum is absolutely worth every penny. I truly cannot believe the miracles this works on my skin. You know how we all dream of a product that just magically makes us look our very best with minimal effort? Well, this is that product. I love the texture and saw results instantly, but it's not one of those serums that starts out great then all of a sudden leaves you with dry skin or breakouts...it keeps getting better the longer you use it, and it layers so wonderfully under moisturizers and makeup. This is a must-buy for me now, and I'm so incredibly grateful I found this! For context, I'm 42 with combination skin that is super sensitive and hates just about everything I put on it.

    Very dry skin

    I have used products recommended by my dermatologist and over the counter. Osea is the best I've ever used. My skin feels and looks great. ❤️ it

    It Cannot Be Beat!

    I LOVE OSEA'S Hyaluronic Sea Serum! It feels luxurious when it goes on my face and makes my skin so firm and supple. You can't beat that when you're 74 years old!

    High humidity must have

    I live in an extremely humid area and I’ve been struggling to find a cream that moisturized, didn’t feel tacky, and didn’t break me out… couldn’t find one. I decided to try OSEA’s hyaluronic sea serum and seal it in with a facial oil instead of using a moisturizer and my skin has never felt or looked better. The best part is, not a single break out since beginning the new routine without any use of irritating actives.

    Like the other reviews recently - bad smell

    I have been buying this product for years and my last order had a TERRIBLE smell - I buy this specifically because I'm sensitive to parfum/fragrance and this is one of thier products that's fragrance-free.

    I've never smelled anything like this before with this product. I emailed them to ask for a refund or replacement and explanation if they changed anything. I really like this product so I'll be really bummed if the smell was due to a change. Hoping it was just a bad batch.

    Hi! We’re happy to share more about your Hyaluronic Sea Serum. Because we use naturally derived, ocean-inspired ingredients, including seaweed, without any added fragrance or essential oils, it’s normal for the scent and color to vary slightly from batch to batch. Seasonal changes and harvest variations in the seaweed can bring out certain natural notes more strongly, giving the formula a subtle, earthy scent. These variations are completely natural and do not affect the quality or effectiveness of the product! Our Customer Care team will be following up with you via email to better understand your experience and find a resolution.

    Not one of my favorite Osea products

    The smell is mild, but unpleasant, and I don't love how it goes on or how my skin feels after. I used to use Osea's anti-aging serum which was amazing, my skin just felt great all the time, and since that got mysteriously discontinued and wiped from the Osea website, I've been trying their other products - I just don't know with this one - the putting on experience is sort of unpleasant, and I don't know if anything is happening. For now I'm using the Dream Night serum which is also not as good as the old anti-aging serum but at least it smells good - meanwhile exploring products from other brands, but I have yet to find something that compares to the Osea anti-aging serum.
