I-Salicylic acid iyisithako esigunyazwe yi-FDA sokunakekela isikhumba esisetshenziselwa ukwelapha izinduna, futhi ukuphela kwe-beta hydroxy acid (BHA) esetshenziswa emikhiqizweni yokunakekelwa kwesikhumba.Iphelele esikhumbeni esinamafutha, i-salicylic acid yaziwa kakhulu ngekhono layo lokuhlanza uwoyela ngokweqile ngaphandle kwama-pores nokunciphisa ukukhiqizwa kukawoyela ukuya phambili.Ngenxa yokuthi i-salicylic acid igcina izimbotshana zihlanzekile futhi zingavalekile, ivimbela ukukhula kwamakhanda amhlophe namakhanda amnyama esikhathini esizayo.I-salicylic acid iphinde ikhiphe isikhumba esifile, futhi izakhiwo zayo zokulwa nokuvuvukala ziyenza ibe isithako esiyinhloko kulabo abane-psoriasis.I-salicylic acid ngokwemvelo ivela kumagxolo omnuzane, amagxolo e-birch amnandi, namaqabunga e-wintergreen, kodwa izinguqulo zokwenziwa zibuye zisetshenziswe emikhiqizweni yokunakekelwa kwesikhumba.
