No, spray tans are not considered harmful to babies. However, it is recommended that pregnant women and children avoid direct contact with the product when being applied as well as during the tanning process. The chemicals used in a spray tan are absorbed through the skin and can be inhaled if sprayed directly into the face or mouth area, so it's best for little ones to stay away from direct contact with these products. Additionally, since babies have delicate skin, it is important to not expose them to any type of harsh beauty treatment or chemical exposure until their skin has fully developed.
