I have not used a mystic tan. I have used a spray tan though. Is it the same thing? My tan looked great too but it does come off. Thank goodness the guy that did it warned me not to freak out after my first shower! I "sprayed" again when I got home and it fades out after about 7-10 days. I don't tan my skin so it was a good alternative to ugly white legs!!!
My sister used Mystic Tan and liked it but says it wore off unevenly.
She told me about L'oreal's Sublime Glow, and I have been using it daily. I have very fair skin and now my legs have a nice light tan.
I never tan naturally -- I would burn if I spent much time in the sun.
About once a week in the summer (and pre-cruise!) I use L'Oreal's Sublime Bronze Gel. I like it because it gives a natural looking tan, and doesn't streak or look orange. I also keep it up daily with a moisturing body lotion Vaseline's Body Glow. Beats getting sunburned!
