Objective: To develop a sunscreen formula with spectral selectivity that filters harmful light (280-550 nm) while allowing beneficial light (550-760 nm) to permeate and thus to boost collagen generation.
Methods: A variety of sunscreen filters and their combinations were tested for transmittance spectrum. The spectral selectivity was quantified by Selection Index (SI), and the optimal formula was identified.
