The Truth About Dairy and Breakouts
Acne is frustrating enough without having to wonder if your morning latte is making it worse. Some people swear that cutting out dairy cleared their skin, while others see no difference.
So, does milk really trigger breakouts, or is it just another skincare myth?
The answer isn’t black and white—it depends on your hormones, genetics, and what else you’re eating.
We’ll break it down and see if dairy is to blame.
Key Notes
Milk, especially skim, has been linked to acne – likely due to hormones and insulin spikes.
Cheese and yogurt may not have the same effect as they don’t raise insulin as much.
Dairy affects people differently – genetics, hormones, and diet all play a role.
Cutting dairy for 4 weeks can help, then reintroduce it slowly to see changes.
Plant-based milk isn’t always better. Some spike insulin, which can also trigger breakouts.
Does Dairy Really Cause Acne?
Scientists have been studying the dairy-acne link for years, and while the results aren’t black and white, some studies do suggest a connection.
While dairy doesn’t cause acne for everyone, there is enough evidence to suggest it can be a trigger for some people—especially milk drinkers.
Milk & Acne
Multiple studies have found that milk consumption—especially skim milk—is linked to increased acne.
One study published in the Journal of the American Academy of Dermatology found that people who drank more milk had higher rates of acne than those who didn’t.
Cheese & Yogurt
Interestingly, cheese and yogurt don’t seem to have the same acne-triggering effects as milk.
Researchers believe this could be due to differences in how they’re processed and their lower insulin-boosting effects.
Whole vs. Skim Milk
Skim milk appears to be worse for acne than whole milk, possibly because of the way it affects insulin and hormone levels in the body.
Why Might Dairy Cause Acne?
Scientists don’t have a definitive answer, but there are a few solid theories:
Dairy Contains Natural Hormones
Milk naturally contains hormones like IGF-1 (insulin-like growth factor 1) and estrogens, which can stimulate oil production and skin cell turnover—two key factors in acne development.
If your body is already hormone-sensitive, consuming dairy could tip the balance and lead to breakouts.
Dairy Increases Insulin Levels
Milk, especially low-fat or skim milk, causes a spike in insulin levels, even though it’s low in sugar. High insulin levels increase oil production, which can clog pores and worsen acne.
Dairy Might Affect Gut Health
Some experts believe that dairy can contribute to inflammation and disrupt gut bacteria, both of which are linked to acne.
If dairy is causing gut issues (like bloating, discomfort, or irregular digestion), it could also be impacting your skin.
Not All Dairy is Equal
Not all dairy has the same effect.
Fermented dairy products like yogurt and kefir contain probiotics, which can actually improve gut health and may even help some people’s skin.
On the other hand, highly processed dairy (like sugary lattes or ice cream) might be more problematic due to added sugar and insulin spikes.
How Dairy Can Impact Your Skin
Does Everyone Break Out from Dairy?
No. Some people can drink milk daily and have perfect skin, while others break out immediately.
The reason? Everyone’s body reacts differently.
Genetics Play a Role: Some people are more sensitive to hormonal changes and inflammation, making them more prone to dairy-related breakouts.
Hormonal Balance Matters: If your acne is triggered by hormonal fluctuations, dairy might make things worse. If your acne is more related to stress or bacteria, it may not have much of an impact.
The Rest of Your Diet Counts: If you eat a diet high in processed foods, sugar, and refined carbs, dairy might just be one piece of the puzzle rather than the main cause.
Should You Cut Out Dairy to Improve Your Skin?
If you suspect dairy is triggering your acne, here’s how to test it:
Try a Dairy-Free Experiment
Cut out all dairy (milk, cheese, yogurt, whey protein, etc.) for at least 4 weeks.
Monitor your skin closely. If you see improvement, dairy might be a trigger for you.
Reintroduce It Slowly
If your skin clears up, try adding back small amounts of dairy (like yogurt or cheese) and see how your skin reacts.
If acne returns, you may need to limit or avoid dairy long-term.
Choose Dairy Alternatives
If you want to go dairy-free but still enjoy milk-like beverages, try:
Almond milk (low in sugar, neutral for skin)
Oat milk (can spike insulin, so watch for breakouts)
Coconut milk (good for skin hydration)
Soy milk (contains plant-based estrogens, so monitor how your skin reacts)
Bonus Tip: If you're worried about missing out on calcium and vitamin D, add leafy greens, nuts, seeds, and fortified plant-based milks to your diet.
Frequently Asked Questions
Does eliminating dairy always clear up acne?
Not always. Some people see dramatic improvements, while others see no change. It depends on how your body reacts to dairy and other acne triggers.
Is organic milk better for acne?
Not necessarily. Organic milk still contains natural hormones that might affect the skin, so switching to organic may not prevent dairy-related breakouts.
How long does it take to see changes after cutting dairy?
Most people start noticing improvements within 2-4 weeks of removing dairy from their diet.
Can dairy alternatives cause acne?
It depends. Some plant-based milks (like oat milk) can spike insulin levels, which may contribute to breakouts. Always check for added sugars, which can also trigger acne.
Is yogurt safe for acne-prone skin?
Yogurt is less likely to trigger acne than milk because it contains probiotics, which may help balance gut bacteria and reduce inflammation. However, results vary by person.
Conclusion
So, can dairy cause acne? For some people, yes.
Milk—especially skim milk—has been linked to breakouts in multiple studies, likely due to hormones, insulin spikes, and gut health effects. However, not everyone will break out from dairy, and factors like genetics, overall diet, and hormone balance play a huge role.
If you suspect dairy is making your acne worse, the best approach is to cut it out for a few weeks and see what happens. If your skin improves, you have your answer. If not, there may be other factors at play.
Ultimately, there’s no one-size-fits-all solution, but understanding how dairy affects your body can help you make the best choice for your skin.
