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.

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 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.

This is my go to serum for years now. I'm 46 years old and get often asked if I am lying about my age. My youthful skin has everything to do with my Osmosis skin care routine. I will stick to it forever. JoElla gives amazing guidance on all their products and is a great one to ask about Osmisis if you have certain things you'd like to improve.
