Does Milk Really Worsen Acne? A Dermatologist’s View

If you struggle with acne, you’ve probably heard advice like, “Stop drinking milk, it causes pimples.” But is this really true? Or just another skincare myth? As dermatologists, we hear this question almost daily. Let’s clear the confusion.

What’s Inside Milk That Can Affect Acne?

1. Hormones in Milk

Cow’s milk naturally contains hormones like androgens and insulin-like growth factor (IGF-1). These can increase oil (sebum) production in your skin, which may trigger breakouts.

2. Insulin Spike

Milk, especially when combined with sugar (like in tea, coffee, or milkshakes), raises insulin levels. High insulin can also increase sebum and inflammation, both of which worsen acne.

3. Skim Milk vs. Whole Milk

Research shows skim milk (fat-free) may trigger acne more than whole milk. This could be due to higher levels of certain proteins in skim milk.

What Does Science Say?

• Several studies have found a link between milk consumption and acne, especially in teenagers.

• But it’s not the same for everyone. Some people drink milk daily and never get pimples, while others notice flare-ups after even a single glass.

• Fermented milk products (like curd or yogurt) may be better tolerated, as they contain probiotics that support gut health.

Should You Stop Drinking Milk If You Have Acne?

Not always. Instead of cutting it out completely, you can:

• Observe your skin – keep a food diary and see if breakouts happen after drinking milk.

• Limit skim milk – try whole milk or reduce quantity.

• Switch to alternatives – almond milk, soy milk, or oat milk (but check for added sugars).

• Choose curd or buttermilk instead of plain milk—these are easier on the skin.

Dermatologist’s Advice

• If you have persistent acne, don’t rely only on diet changes—seek proper medical treatment.

• Milk may be a trigger, but it’s not the root cause of acne. Hormones, genetics, stress, and skincare habits play a bigger role.

• Focus on a balanced diet with less sugar, oily food, and junk—these have stronger links to acne than milk alone.

Bottom Line

Yes, milk can worsen acne in some people, especially skim milk. But it’s not a universal rule. For some, it has no effect at all. The best approach is to listen to your skin and consult a dermatologist if breakouts keep returning.

Remember: Milk may be one piece of the acne puzzle—but it’s never the whole story.
