I offer 2 types of tans- Rapid and Standard.
Rapid is a tan that allows you to rinse with no soap 3 hours after your initial appointment and the color develops for 24 hours.
Standard requires you to shower 8-10 hours after your initial appointment.
The only real difference between the two is the rinse time stated above. In most cases the length the tan lasts is the same for both.
I personally use both products and believe everyone should try both to decide which works best for their skin and lifestyle. Both Rapid and Standard tans have varying shades and colors so there is plenty of room for adjustments with both products.
