Dermikem OC is a combination of a potent topical steroid, antibiotic, and antifungal. It should not be used for acne / pimples as topical steroids will eventually make the acne worse, and an antifungal is of no benefit for pimples. There are better, more effective topical agents for acne which your dermatologist can prescribe for you after a complete assessment.
You should always seek advice from a certified specialist for your particular skin and body type. Self-medication with Dermikem OC, or any other product, is not recommended, and can adversely affect your skin and overall health.
