Who shouldn't use it: Stepping into a spray tan booth can feel confining. If you have asthma, or get claustrophobic when in tight spaces, avoid enclosed spray tan booths. Instead, look for one with an open air design.
Self-tanners should never come in contact with your eyes, nostrils, or lips. Close your eyes or, better yet, wear protective eyewear.
Avoid tanning products that list alcohol as a primary ingredient, as these tend to dry the skin.
