My fair skin does not tan easily and I'm thinking of trying out some of those self tanners this year. Any suggestions on one that has worked welll for you?
|DHA Safety Considerations For the 24 hours after self-tanner is applied, the skin is especially susceptible to free-radical damage from sunlight, according to a 2007 study led by Katinka Jung of the Gematria Test Lab in Berlin. Forty minutes after the researchers treated skin samples with active ingredient in self-tanners, Dihydroxyalcetone, sometimes termed under the acroynm DHA, they found that more than 180 percent additional free radicals formed during sun exposure compared with untreated skin. Another self-tanner ingredient, erythulose, produced a similar response. The interaction between the chemical-bronzing process and UV light overloads the skin's free-radical defense system, according to Jung and her colleague Thomas Herrling. For a day after self-tanner application, excessive sun exposure should be avoided and sunscreen should be worn outdoors, they say; an antioxidant cream could also minimize free radical production. Although some self-tanners contain sunscreen, its effect will not last long after application, and a fake tan itself will not protect the skin from UV exposure.|
