How long does an airbrush spray tan last?

Your body constantly 'sloughs off' dead skin cells. This is why natural sun tans fade over a few days. Spray tanning only affects the outer skin layer, so again, as your skin cells are naturally shed, the spray tan will fade. Your tan should last 5-10 days, typically 7 days, but longer if you look after your skin by moisturizing every day. However, we cannot offer a guarantee as everyone is different.
