    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!
