As demonstrated by the simultaneous proliferation of tanning salons and a tremendous growth in interest in new agents that may reverse photoaging or at least wrinkles that accompany tanning, many people want both.¹ In this month's Archives of Dermatology, Bech-Thomsen and colleagues² present provocative data suggesting that in hairless mice, preirradiation with long-wave (A range) ultraviolet radiation (UV-A), similar to the wavelengths emitted by most tanning salon units, provides significant protection against the development of skin tumors in mice subsequently exposed to broad-band ultraviolet radiation (ie, the sun). These well-designed experiments suggest that, at least in the hairless mouse, a brief visit to a tanning parlor before exposure to the sun (ie, both sunburn-spectrum [B range] ultraviolet radiation [UV-B] and UV-A) might help reduce the risk of sun-induced nonmelanoma skin cancer. Somewhat surprisingly, the authors do not relate this apparent protective effect of preirradiation to increases in skin . . . [Full Text PDF of this Article]
