If you're considering using salicylic acid and propolis, it's important to understand how these two substances work. Salicylic acid is a keratolytic agent, meaning that it breaks down the bonds between cells in the skin. This allows the dead skin cells to shed more easily, which can help to unclog pores and reduce inflammation. Propolis, on the other hand, is an antimicrobial agent that can help to kill bacteria and fungi. It also has anti-inflammatory properties. When used together, these two substances can be quite effective in treating acne and other skin conditions.
