Those who have sensitive skin or allergies should not get a spray tan. This is because some of the ingredients in the tanning solution can cause an allergic reaction. Pregnant or breastfeeding people should also avoid spray tans, as the ingredients can be absorbed through the skin and potentially affect the baby. Additionally, it's not a good idea to spray tan if you have sunburn as it may contribute to the burning sensation, and peeling skin will remove the chemical used to color your skin. Lastly, people who have recently exfoliated, shaved, or waxed should avoid getting a spray tan, as the chemicals can irritate freshly opened pores.
