I have liked this brand and other products I have tried. I’ve been sticking this one out but it’s difficult bc it just sits on your skin and looks orange. Not good for going to bed or wearing for the day. I haven’t noticed any change since using it

Really hoped I would like it after reading the reviews. It’s a brown color that does not blend into the skin. It sits on top and makes the skin look a bit orange, not tan.  Even with mixing it with my moisturizer it is weird.  That said, I’ve been using it since the purchase in my August. I have actually seen a decline in my skin since using it. Before switching I was using the Revisions Vit C. My skin looked better with that. I thought I would try this since I was ordering the Stemfactor. The jury is still out on that. I will be switching back to Revisions, or SkinCeuticals. 

I didn’t notice any difference at all after finishing the whole bottle. Its expensive and once again, having to purchase and use the ‘activating mist’ is very inconvenient. I will go back to my CE Ferulic. It’s the same price and works amazingly! 

I wanted to love this product, especially for the price. But I can't seem to use it. If I use it at night, I wake up with orange stains all over my pillow and blankets. If I use it in the day, it make my make up "pill up". I even tried using the tiniest bit of it. I let it dry down completely before I layer on the rest of routine and make up. I tried mixing it with my moisturizer, still made my make up pill up. So sadly, I will continue to use it as best as I can, till I run out of product. But I will not be repurchasing.

I have been using this product for about the last 3yrs. I now have hardly any pores and my skin tone is better. I wish Osmosis was around when I was younger instead my skin looks better now than it did in my 20's. I highly recommend this to everyone and I have tried many, many facial products. None compare to this one.

I did notice some improvements osmosis is great makes my skin feel great! I have been using this for a while now and love it

I don't get all the raves for this product. It's very expensive and did nothing for my skin. I also bought the Rescue, same deal. I used the entire bottle of each and did not see any benefit. I consider myself a skincare guru and feel duped by good marketing on this product.

Switched from SkinCeuticals to Osmosis Catalyst and so happy I did. I think this product gets a bad rep because of its dark color. I use 1/2 a pump and mix it with the 1 pump of CosRx Snail Mucin. Couldn't be happier with the results.

If I could have only 1 skincare product in the world it would be this one! I have hyperpigmentation, old acne scars, beginnings of fine lines/ wrinkles, elasticity loss, etc. and I get the permanent visible results that every person wants to see. After using two bottles, I actually had co-workers come up to me and tell me my skin looked "really nice" out of nowhere. It significantly eliminated the scaring, blemishes, and visibly shrank my pores. Some think it's too pricy but most people are spending money on garbage products. I got rid of all my Sephora products to make room for this baby! Only small down side is that I won't wear it in the morning if I have to go to work because it's very thick and dark. I like to think that it's because there's so many wonderful potent ingredients inside so I keep to nights and days off. Yay!! So happy my old esty introduced me to this product!

Its a really great serum but I only use at night because of the color and im so pale.
