    Best hyaluronic acid I've ever used!!

    By far the best hyaluronic acid ever! I had such a terrible reaction to a different high end hyaluronic acid that I was actually hesitant about trying this. But after reading the reviews I decided take the chance. And boy am I glad. I no longer have flaky skin and within 2 week all the dark spots and acne marks completely disappeared.

    Pair with a cream for better hydration!

    I have dehydrated, combination skin which is sensitive and blemish prone on my T zone. It isn't as hydrating as I expected for the price paid. I have to put some Atmospheric Protection Cream on top of the serum to get some moisture.

    complexion magic without harsh chemicals

    for my 54th birthday I bought myself some Osea skincare to replace my usual drugstore junk. This serum really balances my skin which tends to be on the dry side, one drop can cover your entire face. I really love how gentle these products are and how they make my skin feel - smooth and clear. Its magical.

    Burst of refresh

    After cleansing, I use two drops and splash it on my face and neck for a refreshing and tightening feeling mask.

    Miracle Worker

    I'm obsessed with this product. A little bit goes a long way, and the slip and feel of this serum is so soothing. It soaks into my skin quickly, and I follow with the atmosphere protection cream. I wake up from this routine with a glowing, soft, smooth complexion. Osea has a new customer for life!

    So effective

    Some hyaluronic products feel like water. This stuff feels legit all day long. I kept wanting to touch my face to feel the the bounce! Highly recommend!
