Abstract
BackgroundAntiseptics are used for the cleansing of acute or chronic wounds to eliminate micro‐organisms from the wound bed. However, they have effects on the skin cells.AimTo determine the effects of hexetidine, povidone–iodine (PI), undecylenamidopropyl‐betaine/polyhexanide (UBP), chlorhexidine, disodium eosin and hydrogen peroxide on human skin fibroblasts.MethodsCCD‐1064Sk cells were treated with hexetidine, PI, UBP, chlorhexidine, disodium eosin or hydrogen peroxide. Spectrophotometry was used to measure cell viability and flow cytometry was used to study apoptosis and necrosis after the treatment. In vitro wound scratch assays were performed to determine the gap closure.ResultsAll antiseptics significantly reduced the viability of human skin fibroblasts compared with controls. The percentage wound closure was lower with hexetidine, PI and UBP. The scratch assay could not be measured after treatments with chlorhexidine, disodium eosin or hydrogen peroxide, owing to their cytotoxicity. The apoptosis/necrosis experiments evidenced a significant reduction in viable cells compared with controls. An increased percentage of apoptotic cells was observed after treatment with all antiseptics. Compared with controls, the percentage of necrotic cells was significantly increased with all antiseptics except for hexetidine.ConclusionThe proliferation, migration and viability of human skin fibroblasts are reduced by treatment with hexetidine, PI, UBP, chlorhexidine, disodium eosin and hydrogen peroxide.
