How can i totally reduce pimples?

Acne: Wash face w gentle cleanser 2x/day ; use oil free products. No oily hair or heavy foundations. Try not to pop pimples. Avoid touching face (cradling chin in hands). Remove makeup before bed. Shower after strenuous exercise. Consider otc products (salicylic acid or benzoyl peroxide). Retinoids/ comedone extractor can be helpful for black heads. If > mild acne see dermatology.

Manage them: If topical benzoyl peroxide as tolerated has not cleared you in two weeks, get with your personal physician. Acne can't be cured but will eventually remit on its own. Until then, you must manage it as a chronic illness.
