Yes, dairy can contribute to acne in some people — but it varies from person to person.
π How Dairy Might Trigger Acne:
-
Hormones in Milk:
-
Cow’s milk (especially skim) contains natural hormones like IGF-1 (insulin-like growth factor-1), which may increase oil production and clog pores.
-
-
Insulin Spikes:
-
Dairy, particularly low-fat milk, can raise insulin levels, which may worsen acne in people who are insulin-sensitive.
-
-
Inflammation:
-
Some people may have a mild intolerance or sensitivity to dairy, which triggers inflammation — a key factor in acne.
-
-
Whey and Casein Proteins (in dairy-based protein powders):
-
These proteins can stimulate IGF-1 and worsen breakouts, especially on the jawline, chest, and back.
-
π§ Not All Dairy Affects Everyone the Same:
-
Some people react to milk but not cheese or yogurt.
-
Fermented dairy (like kefir or Greek yogurt) may be better tolerated and even help skin via gut health benefits.
-
Skim milk is more linked to acne than whole milk in some studies.
✅ What You Can Do:
-
Try a 2–4 week dairy-free trial and observe any changes in your skin.
-
Consider switching to plant-based alternatives like almond, oat, or soy milk.
-
Focus on a balanced diet with plenty of whole foods, fruits, and vegetables to reduce inflammation.
