Photoprotection by sunscreens
Abstract
Ultraviolet (UV) radiation is an etiologic factor for the development of nonmelanoma skin cancers and also possibly melanoma. The American Academy of Dermatology currently recommends the daily use of sunscreens with a sun protection factor (SPF) of 15 or above. The SPF numerical rating is an in vivo, standardized measure of sunscreen efficacy. SPF assessment predominantly reflects the ability of a product to screen UVB radiation. The physical and biologic properties of UVA radiation are relevant as UVA contributes to photoimmunosuppression and photocarcinogenesis. An ideal sunscreen assessment system would address both UVB and UVA protection. However, the SPF rating should continue to serve as the major determinant of sunscreen efficacy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
