Background: Near-infrared (NIR) and UV radiation have been reported to alter skin physiology, causing oxidative stress, mitochondrial genetic damage, and potentially leading to cancer and photoageing. NIR screening is recommended, but only inorganic sunscreens such as zinc and titanium oxide are known to absorb, reflect, and scatter NIR. Additionally, NIR spectra of common organic sunscreens are neither available in the literature nor in technical datasheets. Aim: This study characterizes NIR absorption of several commercial sunscreens and alternative lichen compounds. Methods: To measure NIR absorbance and reflectance spectra, solid organic sunscreens were impregnated with minimal chloroform onto pure dry potassium bromide (KBr) crystals and analyzed using a Varian Cary 5000 spectrophotometer. Liquid compounds were tested directly in standard 1 cm quartz cells. Reflectance spectra were processed using the Kubelka-Monk equation. Results: Sunscreens and lichen compounds effectively absorb radiation beyond 1500 nm, especially above 2100 nm, with less-substituted aromatic compounds such as sunscreens and methyl orsellinate performing better than more substituted ones like pseudocypherellin A and methyl 2,4-dihydroxy-3,5,6-trimethylbenzoate. Additionally, less-substituted compounds exhibited minor absorption bands between 1000 and 1500 nm. Conclusions: Compounds with hydroxyl, carbonyl groups, medium-length aliphatic chains, and low degree of aromatic substitution may provide NIR photoprotection. Owing to their antioxidant properties, lichen compounds are better alternatives. NIR spectroscopy is also suitable for quantification and quality control of sunscreens due to their high concentrations in finished products. However, there is still a need to develop or discover new organic sunscreens with strong NIR absorption.
