4. DHA does not damage the skin as it does not penetrate beyond the stratum corneum or dead skin surface layer. It is considered a safe skin colouring agent and nutritional supplement and has been approved for cosmetic use by most regulating authorities. See: http://en.wikipedia.org/wiki/Dihydroxyacetone.
5. Once the darkening effect has occurred, the tan will not sweat off or wash away with soap or water. It will fade gradually over 3-10 days, in conjunction with the skin's normal exfoliation process. Exfoliation, prolonged water submersion, or heavy sweating can lighten the tan, as these all contribute to rapid dead skin cell exfoliation.
6. 2), a Pt wire as counter electrode and a reference electrode of Ag/AgCl was electrolysed under a 1.1 potential (vs Ag/AgCl) by using a CH Instruments (Austin, TX) potentiostat CHI630B Electrochemical Workstation. The concentration of products was monitored by withdrawing reaction samples of 10 μL. All chemicals were purchased from Aldrich (St. Louis, MO).
