    10/10

    This is the only thing that saved my dry skin! I used it while on tretinoin and in the winter, and since I live in Alaska, it is extra dry, lol! I would only have to apply it once or twice, and it would curb the dryness all day! It's a thicker moisturizer, but it applies really nice and smooth.

    Nope

    Wanted to like this, because I love most all of Oseas stuff. This dried my skin out. I kept trying it over the hyaluronic sea serum and it just was so dry. Makes no sense? I always end up washing it off and just using the collagen dream night cream. Otherwise you can see dry skin under my makeup if I use this stuff. Seems to be the only moisturizing face product I’ve used so far😬

    Allergic reaction

    Tried a sample sent with my order. An hour later my under eye area began to itch/burn. I washed my face, worried that it might be irritating my skin. Woke up the next morning with my eyes massively swollen and hives all over my face and down my neck. Beware of potential sensitivity.

    wonderfully clean and luxurious

    i stopped using all skincare because i had trouble finding products that were completely clean, actually worked, and didn’t irritate my sensitive skin. besides my homemade organic tallow balm, Osea products are now the only thing i trust to deliver results without the toxins. i use this morning and night as a spot treatment for any fine lines and after a shower i use all over my face under a cream. i’ve had the mini for a month but just ordered the full size! totally worth it babes :-) i’m 26 and use it to prevent fine lines from turning into deep wrinkles
