If you have been using Acnicin gel and Markal calamine lotion for two months without much improvement, your acne may need a different or stronger treatment. Continue keeping your face clean by washing it twice daily, avoid oily or heavy skincare products, and do not squeeze pimples. Treatments containing ingredients like salicylic acid, benzoyl peroxide, or retinoids may help control acne more effectively. It is best to consult a dermatologist, who can examine your skin and adjust the treatment to help reduce acne and prevent future breakouts.
