The longevity of a spray tan can vary, and there are a few interesting factors at play, including hormones. Taking all of this into account, one can expect a spray tan to last five to 10 days. Alexandra DiMarchi of Tan-Luxe told InStyle that the individual can play a big role in how long a glow lasts. "The longevity of the tan varies due to someone's lifestyle, beauty/skincare routine, and the pre-and post-tan care," she explained. "The shade you chose also determines this. For example: if someone wants a light skin finish, it may fade off quicker due to a lighter application."
Jules Von Hep of Isle of Paradis warned that periods can impact a tan, saying that when clients are having their periods or are about to begin their menstrual cycle, the tan doesn't penetrate as deeply due to the variation in hormones.
There are a few other products and habits one should avoid to keep a tan lasting its longest. Shaving and robust exfoliation will slough away the tan; oil-based moisturizers can also reduce its lifespan.
Using water-based moisturizers will keep skin hydrated and dewy without prematurely removing a spray tan, as part of an effective ritual of what you should do after a spray tan.
