Hormonal Acne and Diet: Is There Really a Connection?
If you have dealt with hormonal acne, you have heard the advice "just stop eating all dairy" or "cut out all the sugar and it'll clear up." But is any of it true, or is hormonal acne just something your genes and hormones do to you no matter what? Unfortunately, it's a bit of both - there is a connection, but it's not nearly as simple as "just stop eating X food".
What is causing hormonal acne
Hormonal acne tends to occur due to fluctuations of androgen hormones such as testosterone, which increase the production of oil in the skin, among other things. This means that a lot of people experience increased breakouts close to their periods, puberty, PCOS, or other hormonal fluctuations. Hormonal acne also tends to run in families so if your mom or dad had it, you're more likely to have it as well. So overall it has very limited connection to your diet - acne is more affected by your genetics, hormones, stress levels, sleep schedule, and skincare routine rather than the food you eat.
So what's the deal with food then?
Well, there are some studies suggesting that certain types of food may contribute to breakouts occuring or worsening in some people. Keep in mind that those studies are often inconclusive or inconsistent with some showing no effect, and those that do show an effect often can't decide whether it's dairy or high glycemic carbs that are to blame. High glycemic foods and dairy seem to be the biggest culprit though in most cases, possibly due to their connection to IGF-1 and insulin resistance. Some studies even show that skim milk specifically may have a stronger connection to acne than other dairy products. On the other hand, many of those same studies show that those foods don't have much effect on most people, and for some people, diet seems to have very little effect on their skin overall. For those people, cutting out certain foods won't do much of anything. Most of the connection between food and skin seems to depend on the individual and how strongly their body reacts to certain foods.
Foods that could potentially cause breakouts (for some people) might include:
• Milk and other dairy products
• White flour and other refined wheat products
• White rice and other refined carb starches
• Soda, juice, and other sugary beverages
• Candy and other sweet desserts
• Potato chips and other highly processed salty snacks
• Whey protein shakes and supplements
• Fast food and highly processed meals
• Breakfast cereals made with white flour and lots of added sugars
It's rarely just one thing
As mentioned above, hormonal acne is rarely caused by one specific thing. Hormonal acne is called "hormonal" for a reason - it tends to be driven by hormones, specifically androgens such as testosterone. It can also be caused by PCOS, your birth control pills, your periods, stress, sleep schedule, or even genetics. This is why two people could have very different experiences with the same foods. One person might breakout eating dairy while the other might breakout eating fast food while the third might breakout from eating too many sugary desserts and the last might not breakout from any of those things. Everyone's bodies are different, and everyone has a different mix of potential causes for their breakouts.
What can you actually do about it?
If you want to, you can experiment a little with your diet to see how your skin reacts to certain foods and potentially cut those out. But you shouldn't put too much pressure on it since individual results may vary wildly and diet isn't nearly as big a factor for most people as hormones or skincare. Focus on eating healthy, sleeping enough, and managing stress as best as you can - those are the things that will improve most people's skin the most.
However, if you have serious breakouts, it's probably best to talk to a dermatologist rather than trying to figure it out yourself.
A dermatologist will be able to help you more effectively and faster than you can do on your own. This goes double for any form of hormonal acne since it's usually caused by things a dermatologist can prescribe medication against. Diet can support your treatment but it's rarely a replacement for actual medication and skincare.
