Salicylic Acid + Lactic Acid


This is a topical solution indicated in the treatment of warts, corns and calluses.

Information For Patients
  • Warts: A wart is a viral infection of the surface layers of the skin. The incubation period varies from a few weeks to several months. Warts can spread by direct contact with a wart to damaged skin.
  • Corns: A corn is a small, hardened area of skin which often looks yellow compared to the surrounding skin. It is typically round or cone-shaped, pointing down into the skin. Corns most often form on the feet and sometimes on the hands and are caused by constant or repeated friction or pressure.
  • Calluses: A callus is rough, thickened skin spread over a wide area. Like a corn, it is caused by constant or repeated friction or pressure, but unlike corns, calluses are flat and have normal skin markings.


Salicylic acid is a widely used and effective keratolytic, it produces desquamation and destruction of the epithelium by solubilising the intercellular cement of the Stratum Corneum. Lactic acid affects the keratinisation process, reducing hyperkeratosis and is also caustic, leading to the destruction of hyperkeratotic tissue. Collodion is derived from cellulose in a base containing ethanol and ether. It allows easy and accurate application of the product and dries to leave a film which hydrates the tissue and facilitates penetration of the active ingredients.
