great product! A close friend who is an aesthetician and only uses osmosis got me to try this, and I can see the difference in my skin. I use it either alternating with or sometimes combined with Replenish at night and am very pleased.

I have been using Osmosis products for 18 months now and my skin has never looked better. The Stem Factor is the base for my Catalyst Plus in the morning and Correct in the evening.

I purchased this product to use along with the Osmosis AC-11. I mixed the two products together, so it is sort of hard to tell how it performs on its own, but will give it 4 stars because the two products together seem to have a good result.

Works so great for sensitive skin, helps with wrinkles and anti-aging. Give it a try. Skin looks younger and I like that it has natural ingredients.

I've been using Osmosis products for 3 years. StemFactor was the first product my aesthetician recommended and it, along with the other Osmosis products I use-Catalyst AC 11 and Renew have made a tremendous difference in my skin quality. The prices on your site were the lowest I found. Will buy again from you.
