Been using Catalyst AC for a year with great results

1/5/2022 by megumi

My skin is getting dryer as I get older and I was starting to get brown spots on my cheek. I used this all of 2021 with Cleanse, Mist and Quench and my skin looks renewed. Month 5 is when I really started to see results with the brown spots. It's kinda an amber color so I use it in the evening. Smells great. Just added in Correct and my skin is even brighter (been using it in the AM for just one month).

Stops colds sores from forming!

2/21/2018 by janet

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

10/13/2017 by Peony Thunder

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.
