Sunless Tanning Side Effects
Self tanners can cause your skin to become irritated or break out in a rash if you have a known allergy to DHA or erythrulos.
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.
A word on tanning pills
Tanning pills are made with high doses of a chemical called canthaxanthin. Canthaxanthin is a type of color additive found in food when used in small doses. (It's sometimes used in chicken feed to enhance the color of the egg yolk.) When used in high amounts, such as in tanning pills, canthaxanthin can potentially cause hepatitis, digestive system damage, and the formation of yellow deposits in the retina. In any case, stay away from tanning pills.
Avoid tanning products that list alcohol as a primary ingredient, as these tend to dry the skin.
