If you have sensitive skin, this is a great retinol. If you want to see results, not so much. It glides on nicely and doesn’t cause irritation but I didn’t notice any changes in my skin at all. Very annoying you have to also use an activating mist. 

I have been using this line for over a year and I cannot recommend it enough.  I have seen drastic difference in tone and firmness.  I cannot use prescription Retinol products bc they are too harsh for me.  I have also seen many friends that do use them that glassy thin skin look.  This is as effective without the irritation.  Osmosis has different levels so if you are new to retinol I would start with the lower percentage and work up to this one just in case.  I also must recommend the Boost spray with their products bc it is concentrated and needs to be mixed to go on thin.  The Catalyst AC is a also a FABULOUS product but it must be mixed with Boost to thin it to the right consistency.  Most people that don't like Osmosis don't us them with Boost and think they are too sticky and thick.

I have been using these products for three years. Works well with consistent facials. This line has changed my skin for the better.

I have been loyal to skinmedica retinol cream for over a year now but was looking for a retinol serum because it’s able to penetrate the skin better.  I am glad I did my research and tried this retinol: it’s very gentle and the next morning my skin looks glowing. I use it every night after cleansing and toning and just use my eminence moisturizer right after. Yes, it’s a little orange when you first out it on, but after a minute it goes away.  

Since switching from a retinol to a retin-a my skin has never been happier. This does not dry out at all. I am on my second bottle and it’s a game changer.

I first stated off with the Osmosis Correct which was great! Then I went to Renew, my skin loves it. I think it is gentle and does not make me peel, which is very important to me. I use it every night right from the beginning.

I was looking forward to this but it has like a tanner in it & leaves ur skin orange! That should be advertised more. Not just "glow". Returning it & sad. Thank you.

I have significant scarring from cystic acne when I was a teen. Renew combined with Catalyst AC-11 has been a miracle for my skin. My skin has never looked smoother.

I absolutely love the Osmosis brand and can't live without Renew. I've been using this product for years and I notice a significant difference in my fine lines and also it gives my skin a nice glow the next morning. It's pricey but worth it!

ZERO irritation, love the smell and how incredibly easy it absorbs into the skin! On my 3rd bottle!! Love Osmosis brand! Use several of their products and love them all!
