There are several acne skincare products on the market. If you have a severe acne problem you should consult with your doctor for his or her advice on which to use. One way to treat acne is to remove the dead skin from your face that may cause acne.
You do not want to use a product that will do more harm than good. There are products that will take off dead skin cells. But they also remove healthy skin cells as well. This is why you feel a tingling sensation after you use products harsh to your skin.
You will need to remove the bacteria from your face. This is why it is important to wash your face on a regular basis.
In some cases if you have severe acne you might have to use drugs to remove the bacteria. You might have to use a topical product or an oral medication to get rid of the bacteria. Ask your doctor.
The belief that chocolate will lead to acne is not altogether true. There is no one food that will lead to a person developing acne. Of course you might be allergic to a particular food and that might lead to a skin reaction but this is not associated with acne.
