Tanning is composed of two phases; immediate tanning and delayed tanning. Immediate tanning is a quick response to ultraviolet A or visible light, that produces a transient brownish tan. Immediate tanning begins immediately after exposure, reaching a maximum within one to two hours. It will then fade between three to twenty-four hours after exposure (Costin and Hearing, 2007). Immediate tanning starts as a greyish coloration that gradually fades to a brown pigmentation over a period of minutes to days. The response depends on the amount of exposure to radiation as well as skin type. The response is cause by the oxidation of pre-existing melanin and redistribution of melanosomes. Depending on skin type, the visibility of the tan can be almost unnoticeable in fair skin types whereas darker skin types, types IV-VI, it is easily noticeable (Agar and Young,
