Sunless tanning

J AM ACAD DERMATOL VOLUME 57, NUMBER 1
Sunless tanning To the Editor: I read with interest the article by Brooks et al,1 wherein they write ‘‘. . . DHA itself only provides a sun protection factor (SPF) of 3 for the day of application and decreases to under 2 for the 5 to 7 days following application. . . .’’ A sun-protection factor of 3 will block 66% of the erythemic ultraviolet radiation; a sun-protection factor of 2 will block 50% of the erythemic radiation.2 Their statement above seems in conflict with their concluding statement, ‘‘that sunless tanning products containing added sunscreen are only effective in protecting from UV rays during the few hours following application of the sunless tanning product.’’ Michael Caswell, PhD, CCRA, CCRC Rapid Precision Testing Laboratory, Cordova, Tennessee
medical literature and manages to have his voice heard! The mistake of writing ‘‘sine’’ with an accent nonexistent in Latin, which triggered Dr Cappella’s letter1 (and mine some time ago, and which has since been published in another journal2), has already been repeated.3 Similar errors get reinforced and relentlessly repeated. ‘‘Bullosa diabeticorum’’4 and ‘‘xeroderma pigmentosa’’5 are further examples, the correct names being ‘‘bullosis diabeticorum’’ and ‘‘xeroderma pigmentosum.’’ Rigorous nomenclature (exempla gratis, The Dermatology Lexicon Project) is essential to effective research, diagnosis, and treatment.
