Diet may influence acne in some individuals, but it is usually one of many factors rather than the sole cause. Genetics, hormones, skin oil production, inflammation, and skincare habits also play important roles. Research suggests that certain dietary patterns may be associated with acne in some people, although responses vary from person to person.
Some dietary factors that have been studied include:
- High glycemic index foods: Foods that rapidly raise blood sugar—such as sugary drinks, sweets, white bread, and some highly processed snacks—may contribute to acne in some individuals by increasing hormones that stimulate oil production and inflammation.
- Dairy products: Some studies have found an association between milk consumption, particularly skim milk, and acne in certain people. However, the evidence does not show that dairy causes acne in everyone, and more research is needed to understand this relationship.
- Overall dietary patterns: Eating a balanced diet rich in vegetables, fruits, whole grains, legumes, lean proteins, and healthy fats supports overall health and may help reduce inflammation, although no single “anti-acne diet” has been proven to work for everyone.
Keeping a food and symptom diary may help identify whether specific foods appear to trigger breakouts. If you notice a consistent pattern, discuss it with a healthcare professional before making major dietary changes, especially if those changes involve eliminating entire food groups.
It’s also important to avoid restrictive diets unless they are medically indicated, as unnecessary dietary limitations can make it harder to meet nutritional needs.
For most people, dietary changes are not a substitute for evidence-based acne treatment. A comprehensive acne management plan may include appropriate skincare, topical medications, oral medications when indicated, and lifestyle measures. If acne is moderate to severe, causes scarring, or does not improve with over-the-counter treatments, consulting a healthcare professional or dermatologist can help determine the most appropriate treatment approach.
