Generally speaking, diet can play a large factor in overall skin health. While there is minimal research linking any specific foods to acne, some people experience improvements in their skin when reducing their intake of dairy and high-glycemic index foods, such as white bread. Furthermore, eating a well-balanced diet high in nutrient-dense fruits and veggies, whole grains, quality protein, and healthy fats can work in conjunction with other dermatology treatments for your skin. That said, though diet may play a role in the development of your acne, keeping your skin clear of frequent breakouts and painful cysts requires more than just a diet change. It requires professional help from an experienced dermatologist who can recommend effective skin care and acne medication.
