The use of Self Tanning Lotions
As people are becoming aware that UV radiation can lead to skin damage, self tanning lotions are gaining in popularity. This is because they give you a tan without exposing you to the harmful UV radiation of the sun. Most of the tanning lotions have an active ingredient called Dehydroxyacetone (DHA). DHA is a type of sugar which provokes a tan through a chemical reaction that stains the skin. It does not cause an increased production of melanin. Therefore it is not comparable to a tan from sun exposure. So don't be misled: it will not protect you from getting sunburn! However some self tanning lotions also contain a sun protection factor that may give you some protection.
