The scientific consensus strongly supports that exposure to UV rays is the primary external factor in skin aging (photoaging) and a major risk for skin cancers. Meta-analyses and clinical studies, notably published in the Journal of the American Academy of Dermatology, confirm the effectiveness of regular SPF use in preventing this damage. The idea that clouds completely block UV rays is a widely refuted myth, as UVA rays penetrate both clouds and glass. The recommendation to use '2 fingers' of product is a common empirical method in dermatology to ensure the applied quantity is close to that used in clinical testing (2mg/cm²), although the actual amount depends on an individual's morphology. There is no exaggeration here: this practice is considered the gold standard in skin prevention. The advice is therefore robust and based on extensive literature in dermatology.
