Active Fx vs. Fraxel Re:pair for acne scars
I am also considering the Fraxel Re:pair, and weighing the difference between it and Total FX. I am interested in acne scars and have had dermabrasion and CO2. I understand the Re:pair goes deeper than the FX, but I don't quite understand the principle that if it promotes collagen why that would help reduce an acne scar. ie if you had a dimpled piece of fabric and put a flat piece of fabric under it the top layer would still be dimpled.
the depth of penetration between the re:pair and the Fx is not significant in terms of making a treatment difference. they are essentially the same technology. the way they work is by punching thousands of microscopic holes into your skin. the surrounding tissue is unharmed and helps with healing. each of those little holes heals into a more normal patch of skin, so you have thousands of little pixels of normal skin making your skin look smoother.
the collagen stimulation works like a foundation under the skin, making it firmer and giving it support. one of the reasons why acne scars are indented is that they have lost support and have caved in.
hope that helps.
