My name is Gisele and I am a Waxing Specialist at Le Petit Spa. Obagi worked for me ten years ago with excellent results and to this day, Obagi works for me with the same results that I look for. I have 2 months left in my Obagi Nu-Derm System and my skin has definitely improved dramatically! Not only did the dark pigmentation get lighter, my skin is also smoother and firmer.
