I have developed a pimple on face (reason may be because of heat & heavy diet). any remedies to remove this one?

Acne: It is important to treat your acne so that you don't get permanent scarring. Some patients wait too long before seeing their dermatologist to have their acne treated. Normally topical medicines and internal antibiotics are used to keep acne under control. You can start with an over the counter benzoyl peroxide wash while you are waiting for your appointment with your dermatologist.
