can i moisturize before a spray tan

Well, as a mathematics expert, I can tell you some facts about prep work for a spray tan from a logical perspective, although you might want to ask a beauty expert for the best advice. Generally, you should exfoliate and shave at least 24 hours prior to your spray tan, to allow your skin to recover and pores to close. Moisturizing after these steps can help your skin retain hydration.

In a way, yes. You see, overly moisturized skin can create a barrier that hinders the spray tan solution from fully penetrating the skin, so the tan might not be as dark or last as long. Ideally, applying moisturizer should be done well before your spray tan session to avoid this.

Mathematically speaking, if we consider a day as 24 hours, you ideally should moisturize 24 to 48 hours before your spray tan. This gives enough time for the skin to absorb the moisturizer without creating an excess barrier. But again, I would advise asking a beauty expert as this is outside my mathematical domain.

Happy to help! If you have any other questions, especially related to mathematics, feel free to ask.
