There is no minimum age to get a spray tan. Generally, it is recommended that those under the age of 16 and usually those under the age of 18 should not get spray tans. The reasoning behind this is due to the strong chemicals used in spray tan formulas, which can be irritating and dangerous to the skin at a young age. Additionally, some states may require a person to be of legal age (usually 18) before they are allowed to receive a spray tan. It is important to check with local regulations or an aesthetician before scheduling a spray tan appointment.
