Does dairy cause acne?

Last updated 31/01/2025

Acne is a condition which usually presents during puberty. Some adults can get acne too.

It can be caused by changes in hormones which cause the overproduction of oily secretions by glands in our skin. The reasons behind why someone is experiencing acne can be complicated. Things like genetics, skin type and hormones play a part.

So, a simple explanation of acne being 'caused by' any single food is unlikely. There's no sufficient evidence to recommend limiting dairy foods for the management of acne.

In fact, milk is a source of a number of nutrients that have well-known roles in normal skin health, such as riboflavin and iodine. Cutting out dairy foods like milk, cheese and yoghurt means you may miss out on important essential nutrients, and health benefits too (find out more here).

If you're experiencing acne, it’s best to speak to a GP or dermatologist before making any changes, including removing dairy foods.
