I had a treatment under both eyes. Last year I had a similar treatment in NYC with the Erbium laser. The results were good then but the Erbium laser left slightly pink marks under my eyes, as the doctor warned me, for three months.
I have had upper and lower eye surgery in the past, but after a while your eyes need touching up. I am almost 70 and I have no wrinkles at all under my eyes. The Mixto laser is quite a bit better than earlier lasers in both effectiveness and fast healing.
