Dr. Ben Johnson also created and formulated CosMedix Skin Care in approximately 1998.  I have carried both lines, and have known Dr. Johnson professionally from the beginning.   I can tell you without a doubt, my clients have had much more advanced results with Osmosis.

Aside from the many incredible ingredients he uses, Retinaldehyde vs Retinol is the difference.   Retinaldehyde is stronger than Retinol, yet more gentle on the skin.  My clients have seen much more anti-aging benefits with Osmosis.  Once I saw the benefits of Osmosis, I decided it was not necessary to carry CosMedix. I had the best with the Osmosis products

Boost is the strongest anti-aging product in the Osmosis line. Once your skin adjusts to Boost, it will help turn back the clock. Boost is 1000 times stronger than retinol, yet more gentle.  You want to start with the more gentle products in Osmosis first, since Boost is good to use after you have been on the Osmosis line for at least 30 days.
