4. Eat a healthy diet

A balanced diet can help you look and feel your best. Eat plenty of fruits, vegetables, whole grains, and lean proteins. Fresh fruits and vegetables may be especially helpful at preventing damage that can lead to early skin aging. Drink plenty of water to help keep your skin hydrated too. Limit foods and drinks with added sugar, processed snacks, and other refined carbohydrates. Some studies suggest that a diet high in refined carbs stripped of nutrition can speed up aging.

The connection between diet and acne isn't clear. But some research links acne with drinking lots of milk or eating lots of processed foods that raise blood sugar quickly. Limited research suggests that nutrients such as fiber and omega-3 fats show promise at helping control acne. But more studies are needed to be sure.
