Salicylic acid softens and removes psoriatic scales, improving the effectiveness of other topical psoriasis treatments. By reducing scale thickness, it allows medications to better reach the affected skin.
Salicylic acid acts as a keratolytic, meaning it helps to soften and shed the outer layer of skin. In the context of psoriasis, this action is beneficial because it reduces the thickness of psoriatic scales, making it easier for other topical medications to penetrate the skin and exert their therapeutic effects. It does not directly treat the underlying cause of psoriasis but manages the symptoms associated with scale buildup.
