Erythrulose and dihydroxyacetone ( DHA ) are very similar in composition, and both react much the same way on the skin surface.
12.
Erythrulose / DHA reacts with the amino acids in the proteins of the first layers of skin ( the stratum corneum and epidermis ).
13.
Because DHA and erythrulose are very similar in composition, it is not unusual for someone to be sensitive to both DHA and erythrulose.

Not all users develop a tan coloration from erythrulose; some may find their fading is more uneven and blotchy when this ingredient is used.
16.
The systematic name of this enzyme class is "'erythrulose-1-phosphate formaldehyde-lyase ( glycerone-phosphate-forming ) " '.
17.
Forty minutes after the researchers treated skin samples with high levels of erythrulose they found that more than 140 percent additional free radicals formed during sun exposure compared with untreated skin.
18.
The color effect is temporary and fades gradually over 3 to 10 days . Some of these products also use erythrulose which works identically to DHA, but develops more slowly.
19.
Does the fact that it isn't FDA approved mean that it isn't legal to use Erythrulose, or simply that it isn't recommended and the effects are not known?
20.
However, the'tan'produced by erythrulose / DHA only has an SPF of up to 3, and " enhances " the free radical injury from UV ( compared to untreated skin ) for the 24 hours after self-tanner is applied, according to a 2007 study led by Katinka Jung of the Gematria Test Lab in Berlin.
