I HAVE had a few queries about acne.
The cause of pimples is not known, though is probably a mix of factors, including hormones, diet and stress. Many doctors suggest that you make sure you drink enough water, eat a healthy diet, exercise and keep your face clean. If the acne is very bad, you may need to see a dermatologist who can presribe medication for you to treat the acne.
