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!

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.

Magic in a bottle!
This is my favorite serum in the entire line! I've seen amazing things happen on my own skin and on my clients. The results are truly amazing and I will never be without this!
