Sienna X Tan Tips for the best results: Exfoliate & shave the night before. WEAR BAGGY CLOTHES TO APPOINTMENT! DO NOT moisturise on the morning of the tan, do not use any deodorant as this can cause decolouration to the tan. Wear loose clothing to the appointment and avoid socks and tight shoes. Maybe leave the bra off until you wash it off to avoid marks. Avoid touching your skin too often and if you do wash your hands, do so carefully to avoid brown fingertips. If you get wet, pat the area softly and gently blend.
