percentages correspond with the product coloration levels from light to dark. Lighter products are more beginner-friendly, but may require multiple coats to produce the desired colour depth. Darker products produce a dark tan in one coat, but are also more prone to streaking, unevenness, or off-colour tones. The artificial tan takes 2 to 4 hours to begin appearing on the skin surface, and will continue to darken for 24 to 72 hours, depending on formulation type. Once the darkening effect has occurred, the tan will not sweat off or wash away with soap or water. It will fade gradually over 3 to 10 days. Exfoliation, prolonged water submersion, or heavy sweating can lighten the tan, as these all contribute to rapid dead skin cell exfoliation (the dead skin cells are the tinted portion of the sunless tan).

      DHA summary and safety considerations

      For the 24 hours after self-tanner (containing high DHA levels, ~5%) is applied, the skin is especially susceptible to freeradical 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 high levels of DHA they found that more than 180 percent additional free radicals formed during sun exposure compared with untreated skin. Another self-tanner ingredient, erythrulose, produced a similar response at high levels.

      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 minimise 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.

      Although some self-tanners contain sunscreen, its effect will not last as long as the tan. The skin browning of a sunless tan may provide some UV protection (up to SPF 3), but this low-level protection should be supplemented with additional protection. The stated SPF for the product is only applicable for a few hours after application of the self-tanner. Despite darkening of the skin, an individual is just as susceptible to harmful UV rays, therefore an overall sun protection is still very necessary. DHA-based sunless tanning has been recommended by the Skin Cancer Foundation, American Academy of Dermatology Association, Canadian Dermatology Association and the American Medical Association as a safer alternative to sun-bathing.

      DHA has been around for over 50 years with no adverse reactions know or shown. The FDA American safety standard has approved it on their list of safe for cosmetic application Buying organic tanning solution with minimal chemicals will give the best browning effect on the skin
