Allergic Reactions The active ingredient in self-tanning lotions and creams is dihydroxyacetone, or DHA. Research led by M. Morren at the Katholieke Universiteit Leuven in Belgium found that some people have contact allergies to DHA. Some people can also be allergic to other ingredients in self-tanning products, such as fragrances and preservatives; none of which are found in 100% Herbal Instant Tan.
Increased Risk of Sunburn A suntan encourages your body to produce more melanin, but a sunless tan does not. When you use a self-tanner, you still need to use sunscreen or you are at risk of sunburn and sun damage. A 2010 study led by Vilma E. Cokkinides at the American Cancer Society found that teens who used self-tanners were more likely to engage in other risky tanning behaviors, including using indoor tanning lamps or beds and neglecting to use sunscreen.
Self-tanning Pills Self-tanning pills contain canthaxanthin, a color additive that may cause your skin to turn orange. According to MayoClinic.com, self-tanning pills may cause liver damage and formation of crystals in the retina of the eye. Canthaxanthin is not approved by the FDA for use in tanning pills, but because it is allowed as a color additive in food, some companies use it in tanning pills. Self-tanning pills are considered unsafe for use. A better choice would be 100% Herbal Instant Tan which is a completely herbal/organic ingredient based colorant without the additives/preservatives and chemicals including DHA which is excluded.
