Level 5 - mechanism / opinion, no new human data
Narrative review of mechanisms and clinical effects without primary data or systematic search

What was done
This narrative review summarizes the biological, molecular, and clinical effects of ultraviolet (UV) radiation from sunlight and artificial therapeutic sources on human skin.
What was found
The abstract provides no quantitative data or numerical outcomes. It describes acute effects (sunburn erythema, tanning, immunosuppression), molecular mechanisms (formation of cyclobutane pyrimidine dimers and [6-4] photoproducts repaired via nucleotide excision repair), and chronic outcomes (photoaging, sustained immune modulation, and photocarcinogenesis). It also notes the therapeutic use of UVB (280–320 nm) and UVA (320–400 nm) for conditions such as psoriasis and vitiligo alongside their associated adverse risks.
Why it matters
The paper outlines the dual nature of UV radiation, contrasting its role as an environmental carcinogen and driver of photoaging with its controlled application in clinical phototherapy.
Limits
The abstract reports no original experimental or clinical data, meta-analytic pooling, or systematic search methodology. Quantitative risk estimates, dose-response relationships, and specific phototherapy protocols are omitted.
