I have been using this product for probably 6 to 7 years. In fact, it wasn't even available on the market when I first used NuNeck Cream. My aesthetician at Avani Derm Spa asked me to trial it & I did & I have been using ever since. I really love it & believe it really helps decrease what I call neck skin checkering. I have a fair complexion and developed turkey neck and checkered skin fairly young. At 65, I had face/neck/brow lift by Dr Nayak (the best plastic surgeon on the planet) & I am now over 9 years post surgery. I am a retired nurse who worked in the operating room for 10 years and scrubbed for a number of plastic surgeons long before Dr Nayak was practicing but I can tell you I know great when I see it and experience it & Dr Nayak's results are nothing but fantastic. I totally believe that achieving long term, continued results is not only due to the developed techniques of Dr Nayak but in taking care of the skin afterward. NuNeck works for me!
