Stops colds sores from forming!

The Catalyst AC-11 is the only product that has helped when I have needed immediate canceling of an impending cold sore or Herpes sore outbreak on my face. After a severe cold I usually get a cold sore/Herpes outbreak. The norm is the swelling and redness and then the pimples that break open and then have to heal. All this could take up to 2 weeks to completely heal. I have put the Catalyst on the red area to stop the pimples from starting or on the pimples themselves and it stops it from proceeding as usual. This is an amazing product and helps heal my skin 3 x's faster than it going through it's own terrible time consuming, painful process.

Glad My Aesthetician recommended OSMOSIS

55 year old, female. My aesthetician - who also personally uses OSMOSIS - helped me select the right mix of OSMOSIS skincare products. I have used the complete line of OSMOSIS skin care including AC-11 for about 2 years. It has effectively reduced skin tags, healed broken capillaries, smoothed fine lines and wrinkles and firmed up the appearance of droopy eyelids. My husband noticed a difference in my appearance and he started using OSMOSIS. The two things I don't really like about this product is the staining on clothes, especially on collars, and the price. I let the serum absorb and dry completely before getting dressed and I signed up for a repeat order discount.

A serum that does what it says!

This serum was the first time I saw really noticable changes in my skin compared to other serums I have used. It's such a game-changer in the treatment room and at home. I got a bad burn from a curling iron on my face and it looked like it was going to leave a bad scar. After just 4 months of using this serum, the wound was completely healed and I had no scar. Truly amazing since I have other burn scars from years ago, and you can bet I'm going to treat those also!

I really love this product. My skin look smooth and radiant. I love it, no other serum has done this to my skin.

Amazing results! Reverse aging! Really, so many skin care lines make exaggerated claims, I am so grateful for Osmosis, 30 years as an Esthetician, I have never seen a skin line as amazing Osmosis.
