Many products, including prescribed medications, over-the-counter patent medecines, and a wide range of personal care products can increase the skin' s sensitivity to UV radiation, also known as photosensitivity. This is an intense reaction of the skin to radiation which can cause burning (or erythema) in a much shorter period than would normally be expected.

Photosentivity can be caused by products applied directly to the skin or from medications or other substances that have been ingested.

Because there are literally hundreds of known photosensitizing agents under the following general categories, clients taking any medications or using any products (some listed below), should be advised to consult a physician or pharmacist before using tanning equipment.
