    Great "C" Serum

    Posted by Lisa B. on 7th Jun 2022

    Another great Osmosis product! This serum goes on with a little color giving my skin a glow (which is what C serums are supposed to do). I have medium/ olive skin tone so this is a plus for me. I can see it's transforming my skin with a slight tightening affect, also using on my eyelids for a lift. Love it!

    Osmosis Catalyst AC-11 DNA Repair Vitamin C

    Posted by Karen Shahwan on 1st May 2022

    I bought the core 4 from the Osmosis Skincare Line. I have sensitive skin with mild rosacea on the cheeks. The consistency of these products are a little different than what I am used to. That being said, I am really loving how my skin is responding to this line. This is a very unique vitamin c serum that requires an activation mist. Once this product is worked in your skin, your skin looks glowy and beautiful. I am so happy with the results I see in my skin in the short time I have been using this product. I will definitely repurchase and recommend!

    I have intense crease lines on my forehead, and I must say this product has already helped in less than a week. It does have a tint to it, so I mix it with another serum or with my face moisture to lessen the orange tone. The hue does wash off and it’s working miracles, so it’s well worth the trouble. This is the first wrinkle serum that I can notice a difference in my fine lines with. I even noticed in a picture of myself. I can’t wait to see the results after continued use!
