Carbonylation measurements: Oxiproteome (A) and malonedialdehyde—MDA (C,D), 4-Hydroxy-nonenal—4-HNE (F,G) and acrolein (I,J) adducts immunostainings from sun-protected (C,F,I) and sun-exposed (D,G,J) human skin (Scale bar = 50 µm). Quantification of dermal protein oxidation from Oxiproteome, dermal MDA, 4-HNE and acrolein were increased in sun-exposed skin as reported in box plot (B,E,H,K, respectively) (* p < 0.05).
