I've been using Catalyst for about a month and not through my first bottle yet. My skin is tighter, brighter and more evenly toned! Definitely look a bit younger. Love this product!

I've only been using it for 2 weeks and no change yet but I didn't expect anything that quickly.

This product seems to have changed a bit since company removed the MD labeling. Seems diluted, not as strong. The older original product was 5 stars.. even though it looked like a terrible spray tan, and would rub off on my pillowcase. My skin seems more even toned and glows when I regularly use this original product.

This serum nurture my skin. I use as mask because it makes a mess in pillow if I use to sleep. But when I remove the product I can feel the difference right away, it really calm my skin and I notice less redness. I've been using 2 weeks and I did not notice any tightening in my eyelid, but it did not cause any irritation when I use :) Sometime I use a little pump in the morning before applying my sunscreen and my skin simply glows. I will definitely buy again.

I am using it on my eyelids for creepiness. I noticed slight results within a week and it took my eyelids about 2-3 years back in time after 3 month of use. I only use it at night

Having tried a zillion repair w/Vita C serums, this is the only one that does not irritate my 67 year old face. It has copper in it so don't be surprised when it comes out a luscious yummy coffee color. for it disappears completely into skin, and then activate it with the appropriate spray. Love it and the improvements it has wrought!!!

I have tried so many different serums, but this by far is the best. I wouldn’t use anything else, but this serum. The whole product line of osmosis is just wonderful. Learned about it while receiving a facial in Las Vegas and I was not disappointed.

I have been using the Catalyst AC-11 DNA Repair C Serum for 3 years as a part of my Osmosis skincare regimen. I use it on my face, neck, and chest every morning. Since it's tinted it gives my skin a nice glow. A little goes a long way with this serum. I also recommend letting it dry on your skin for a minute or two with a small fan, which is what I do, so that it's completely dry and able to set before I spray the booster. I also recommend thoroughly washing your hands after you apply the serum. It's tinted and will stain your towels if they happen to be white like mine. I never go a day without applying this every morning!

I bought this based on some you tube videos claiming that it lifts and firms the hooded eyelid. After a few days of using this my face broke out in a weird way - not pimples, but red inflamed circles in different places. This product is the only one that was new, besides the Osmosis Rescue which I was using for about a week before using this product. I since stopped, and when my face clears up, I will attempt to use this again to see if I get the same results. As far as my eye area is concerned, not sure that I see any significant lifting so far.

I use this at night. I put about a half a pump with a drip of water and rub and rub. My skin does not turn orange if I do this. Best of all, it is transforming my skin. It is beautiful.

I agree with previous review. I believe it works and ingredients are great, but I was not able to use it in the mornings because it makes my face orange, and it does stain my pillowcase terribly. Plus I am not a huge fan of the smell. Otherwise it would make a great product.
