Black Magic tan system is the best out there. As seen on Dancing with the Stars Black Magic gets rave reviews, I currently carry 8 different bases and development times from green base, chocolate, caramel and violet to compliment you skin tone. A consultation will determine which one will suit you.
Tans are at their optimum on day 2, exercise is not advised within 12-24 hours of your tan, exfoliate and shave the day before concentrating on any dry areas, arrive on the day free from moisturisers and deodorant. Please do not use any soap when washing off your tan, you can start to moisturise the following day.
