My face have lot of acne spot, how to remove acne spot in my face and stop acne?

Not curable. You must manage your acne until it remits on its own. If topical benzoyl peroxide as tolerated has not cleared you in two weeks, get with your personal physician who can add some prescription-strength Rx. Since you say you have it only on your face, it's likely that adding a topical antibiotic such as Clindamycin will be sufficient, but if you need something strong, go for it.
