The primary goal of acne prevention is to maintain clear, healthy skin.
You can take the following steps to prevent acne:
Wash your face once to twice daily to remove excess oil, dirt and sweat; use a mild cleanser and your fingers, rather than a washcloth
Determine your skin type; oily skin is prone to pimples, for example, while combination skin is prone to oily skin in the “T-zone” of your forehead, nose, and chin
Moisturize your skin
Use over-the-counter products
Stay hydrated; your skin may respond to dehydration by producing more oil
Limit makeup, as it can clog pores
