Does dairy really cause or worsen acne? ive never noticed my teen acne improve with diet change (tried for 3 months) but still curious..

Probably not!: Science still does not know whether diet and acne are related, but evidence is starting to trickle in. Based on what we are seeing in clinical research, it seems prudent to eat a relatively low-glycemic diet rich in colorful fruits and vegetables and omega-3 fats and to perhaps supplement with 30mg of zinc gluconate per day. However, due to our modern diets and Western style of living, achieving sustainable relief of acne from changes in diet alone remains an elusive goal. No matter what anti-acne diet you embark upon, while you may see a short-term reduction in acne while your body loses weight, symptoms are likely to return as your weight levels off. If your goal is to achieve completely clear skin, your time is likely much better spent effectively treating your skin than chasing any theoretical, yet unproven, diet.
