Love MTII! I've been more tan than ever in my life for nearly a whole year, with minmal sun exposure. I've always had a hard time gereting tan, and staying tan. It took several weeks to build up, then once a week injection and hit the salon once a week I maintained well. Then I went off for a few months, and missed it so much that I never want to be off again, especially since I had to be white again waiting for it to rebuild in my system. The compliments on having an amazing tan never stop!
