Eating oatmeal as part of your diet can help prevent acne outbreaks because Oatmeal contains omega-3 fatty acids that can help fight inflammation as well as being high in zinc.
A lot of acne creams contain zinc so that's one reason that oatmeal helps with acne.
A few good ways of getting rid of acne is to apply some tea tree oil or lemon juice to the acne which will make the acne disappear within a week.
Apply either the Tea Tree oil or lemon juice from a fresh squeezed lemon to the acne 3 times per day and it will get rid of the acne and acne scars.
