Evaluation of dual-effect composition (DEC)-containing serum in modulating cutaneous erythema responses to UV irradiation at varying intensities. (A) Δa* (skin redness), ΔEI (erythema index), and ΔEG (erythema grade) values were quantified. Δvalue = post-irradiation measurement after 4 days of serum application − baseline measurement before serum application. Change (%) = (Δvalueserum − ΔvalueNC)/ΔvalueNC × 100%. *P < 0.05 vs. negative control (NC). (B) Clinical photograph demonstrating photoprotective effects against UV-induced erythema in a 34-year-old female subject (upper back).
