How Sunless Tanners Work
Bronzers: Cosmetic bronzers produce an immediate colour
change and usually wash off with soap and water. Most sunless
tanning products contain a mixture of both bronzers and DHA.
DHA: Also known as dihydrozyacetone is refined from
a vegetable source, most likely sugar beets or sugar cane.
According to the American Academy of Dermatology, the most
effective products available are sunless or self tanning lotions
that contain DHA as the active ingredient.
DHA interacts with the dead cells located in the stratum
corneum (horny layer) of the epidermis. As it interacts with
the cells a colour change occurs.
DHA works with the keratin protein in the top layer of the
skin. This is why the results are temporary; the outer skin
is continually renewing itself.
Erythrulose: Effectively this is the same as DHA,
when the two are used together the result is a longer lasting
tan.
