UVA, UVB and UVC

Let’s start with the tanning process. How does our skin tan indoors? Low-pressure lamps (long tubes) emit a combination of UVA and UVB energy. A minimal, yet effective amount of UVB is necessary to stimulate the melanin in your skin and begin the tanning process. These melanocyte cells are pink in color and when your skin is exposed to UVB, they begin to rise to the top layer of your skin. As they rise, the UVA energy in the sunlamps begins to oxidize (“tan”) the cells to induce a photo-reactive response: a cosmetic tan – which is what you are selling!

UVA: This is the longest ultraviolet light wavelength and is responsible for the actual darkening of the skin. Exposure to UV can cause severe skin reactions if combined with photosensitizing agents found in certain medicines, foods, cosmetics and toiletries. Almost all of the UV radiation that reaches the earth is UVA – as much as 97-99 percent. UVA rays are capable of penetrating the deepest into our skin; through the epidermis, dermis and subcutaneous layers.

UVB: The middle wavelength is UVB. Exposure to UVB is necessary to stimulate the production of melanin cells, which are the darkening pigment in the skin. However, overexposure can cause sunburn. Between 1 and 3 percent of the UV radiation that reaches the earth is UVB.

UVC: UVC is the shortest ultraviolet light wavelength, and practically 100 percent of this energy is blocked or filtered out by the Earth’s ozone layer. Although not used in indoor tanning systems, UVC has germicidal applications, such as sanitizing surgical instruments and water disinfection.
