I-Salicylic acid sisithako esivunyiweyo se-FDA sokhathalelo lwesikhumba esisetyenziselwa ukunyanga amaqhakuva, kwaye kuphela kwe-beta hydroxy acid (BHA) esetyenziswa kwiimveliso zokhathalelo lolusu.Igqibelele ulusu olunamafutha, i-salicylic acid yaziwa kakhulu ngokukwazi ukucoca ioyile engaphezulu kwi-pores kunye nokunciphisa ukuveliswa kweoli ukuya phambili.Ngenxa yokuba i-salicylic acid igcina iipores zicocekile kwaye zingavalwanga, ikhusela iintloko ezimhlophe ezizayo kunye neeblackheads ekuphuhliseni.Iasidi yesalicylic ikwakhupha ulusu olufileyo, kwaye iipropathi zayo ezichasayo ziyenza ibe yeyona nto iphambili kwabo bane psoriasis.I-asidi ye-salicylic ngokwemvelo ivela kwi-willow bark, i-sweet birch bark, kunye namaqabunga e-wintergreen, kodwa iinguqulelo zokwenziwa zisetyenziselwa iimveliso zokunakekelwa kwesikhumba.
