Mechanism of Action

Benzoic acid works as a keratolytic agent, breaking down the outer layer of the skin to facilitate the removal of dead skin cells and improve skin texture. Salicylic acid, also a keratolytic, helps to dissolve the bonds between skin cells, which aids in exfoliating the skin and unclogging pores. Both acids have antimicrobial properties that contribute to reducing bacterial growth and inflammation.

How Long Does It Take to Work?

Patients may start to see improvements within a few days to a week of use. For acne, noticeable results typically appear after 2 to 4 weeks of consistent application. Warts and calluses may take several weeks to months to completely resolve.

Absorption

Benzoic acid and salicylic acid are minimally absorbed through the skin when applied topically. Their effects are primarily localized to the area of application, with minimal systemic absorption.

Route of Elimination

The majority of benzoic acid and salicylic acid are eliminated through the skin and urine. Benzoic acid is metabolized in the liver and excreted in the urine. Salicylic acid is metabolized in the liver and also excreted via the urine.
