Hasaderm is a combination of two topical ingredients, betamethasone and salicylic acid. Accordingly, Hasaderm has anti-inflammatory and keratolytic effects as a dermatological drug used to reduce swelling, redness, itching, and dead skin cells caused by specific skin problems such as psoriasis. The mechanism by which Hasaderm works is that the ingredients work together, reducing the amount of inflammatory chemicals, suppressing the body's natural immune response, and helping to control swelling and inflammation optimally.
