There are many factors that contribute to acne, including sebum and keratin production, acne-causing bacteria, hormones, blocked pores, and inflammation. While diet is not the main cause of acne, certain foods are believed to trigger breakouts. Dairy products, for example, are thought to be one of the leading causes of acne. However, according to the Phoenix Surgical Dermatology Group, they may not be as big of a factor as people think. While cheese is a dairy product, it is unclear whether it directly causes acne.

What You'll Learn
Dairy products and acne
While dairy may not be the main cause of acne, it is thought to be one of the leading triggers. Dairy products can lead to higher levels of insulin and androgens, which can trigger acne. This is particularly true for whey protein, which is found in milk and is also sold as a supplement. Whey has been shown to raise insulin levels, which can worsen acne. However, it's important to note that everyone's experience with acne is unique, and dairy may not be a factor for some people.
If you're struggling with acne and want to see if dairy is a trigger for you, it's recommended to cut down on dairy products like milk, cheese, yoghurt, and cream without eliminating them entirely. Whey protein supplements should also be avoided if breakouts are an issue. It's important to note that other factors, such as genetics, also contribute to acne, and altering your diet may not solve the problem completely.
In addition to dairy, other foods that are thought to trigger acne include sugar, fried foods, chocolate, nuts, and foods high in iodine, such as shrimp and seaweed. A low-glycemic diet may be beneficial for acne-prone individuals as it eliminates spikes in blood sugar that can cause inflammation and increased sebum production, both of which are linked to acne. Proper hydration and a balanced diet with plenty of fruits and vegetables are also important for overall skin health and can help keep inflammation in check.

Hormones and acne
While dairy products do not cause acne per se, certain dairy products can aggravate acne in people who are already prone to it. Dairy products can lead to increased sebum production and inflammation, and they can also contain hormones that trigger breakouts. Whey, a liquid portion of cheese, has been shown to raise insulin levels, which can worsen acne. However, there is insufficient research to establish a direct causal relationship between whey and acne.
Hormonal acne is a common term for acne, especially when it occurs during puberty due to hormonal changes. Hormonal acne is caused by excess sebum, an oily substance that prevents the skin from drying out. This excess sebum clumps together with dead skin cells and clogs pores, resulting in acne lesions or bumps on the skin. These lesions can become inflamed, red, painful, and sore if left untreated.
Hormonal changes, such as those that occur during puberty, pregnancy, menopause, and the menstrual cycle, can trigger hormonal acne. Specifically, fluctuations in testosterone levels can increase sebum production, leading to acne. Testosterone levels typically rise during puberty, causing male development in boys and increasing muscle and bone strength in girls. The glands that secrete sebum are sensitive to testosterone, which is why changes in testosterone levels can impact acne formation.
Hormonal acne is more common in women, with about 50% of women in their 20s and 25% of women in their 40s experiencing it. Women experiencing acne around menopause may have normal androgen levels but lower estrogen levels, and this hormonal imbalance can trigger acne flares. Additionally, conditions such as polycystic ovary syndrome (PCOS) can affect hormone levels and contribute to acne.
While hormonal acne can be challenging to avoid, there are strategies to reduce the risk of breakouts. These include making lifestyle changes to reduce stress, improving sleep quality, adopting a healthy diet, and using skincare products that won't clog pores. It is important to consult a healthcare provider to discuss treatment options for persistent acne and develop a personalized plan.

Insulin levels and acne
While dairy products, such as cheese, do not cause acne per se, they can aggravate the condition if you are already prone to it. Dairy products can lead to increased sebum production and inflammation, and they may also contain hormones that trigger breakouts. One such hormone is insulin, which can be raised by whey, a liquid component of cheese.
Several studies have found a link between high-glycemic diets and acne. High-glycemic foods cause hyperglycemia, which prompts the pancreas to release large quantities of insulin to lower blood sugar levels. This, in turn, can cause a stress response in the adrenal glands, which then release androgens—hormones that can stimulate sebum production and lead to acne.
Compelling evidence exists that high-glycemic load diets can worsen acne by increasing levels of IGF1, a hormone that is stimulated by insulin. Smith et al. found that a low-glycemic load diet for 12 weeks decreased serum IGF-1 levels and significantly improved acne.
High insulin levels can also be caused by insulin resistance, which has been linked to acne. A study found that 81% and 67% of acne patients had insulin resistance based on their C-peptide and TyG index levels, respectively, which was significantly higher than the control group. However, the role of insulin resistance in the development of acne is still not clearly understood.
Overall, while insulin levels may play a role in acne, it is important to note that diet may be just one factor contributing to acne, and other factors such as genetics also play a role.

Whey protein and acne
Dairy products have long been suspected of causing acne. However, according to experts, no food, including dairy, causes acne per se. Nevertheless, certain dairy products can aggravate acne in people who are already prone to it. Dairy products can lead to increased sebum production and inflammation, and they may also contain hormones that trigger breakouts.
Whey protein is the liquid part of milk that separates during cheese production. It is one of the two primary proteins found in milk, the other being casein. Whey protein is a common ingredient in protein bars, cookies, shakes, smoothies, and supplement powders. It is particularly popular among athletes who wish to gain muscle mass and strength.
Several studies have found a link between whey protein supplements and acne. Whey protein raises insulin levels, which can worsen acne. It also increases the production of sebum (oil) in the skin, which may contribute to clogged pores, bacterial overgrowth, and inflammation, leading to acne. A case-control study from Jordan found that a significantly higher proportion of acne-afflicted participants (47%) were taking whey protein supplements than those in the control group (27.7%). Another study found that individuals who consumed more whey protein-containing foods and supplements experienced worsening acne.
However, it is important to note that the existing studies are relatively small and observational, and there is currently no strong evidence to prove a direct causal relationship between whey protein and acne. Nevertheless, if you are taking whey protein supplements and experiencing worsening acne, you may consider switching to a plant-based protein supplement to see if your acne improves.

Iodine and acne
While eating foods that are high in iodine is not necessarily harmful to the skin, if you already have acne, iodine can irritate your skin and cause inflammation, making your acne worse. Iodine is a trace mineral commonly found in seaweed, seafood, iodized salt, fortified bread, vegetables and fruits grown in iodine-rich soil, and many vitamin supplements. When consumed, the body reduces iodine to its iodide component, which is then absorbed into the bloodstream and used by the thyroid gland. Iodides are essential for the manufacture of hormones by the thyroid gland.
High levels of iodine can cause an acne-like reaction on the skin. This reaction, known as iododerma, occurs when iodine is excreted through the pores, leading to irritation and subsequent flare-ups. Those with more susceptible pores are particularly vulnerable to this issue. However, it is not just an excessive amount of iodine that can cause acne; iodine deficiency can also result in an imbalance.
The correlation between iodine and acne is complex and depends on the amount consumed, any supplemental use, and the individual's sensitivity. While it is not the typical iodine intake that triggers acne, overconsumption of iodine can lead to acneiform eruptions—skin disruptions that resemble acne vulgaris but are not the same.
If you have acne, you may want to avoid or limit your intake of iodine-rich foods. Alternatively, you can talk to your doctor or dermatologist about whether taking an iodine supplement is right for you.

Cheese, being a dairy product, is believed to be one of the leading causes of acne. Dairy products can lead to increased sebum production and inflammation, and can also contain hormones that can trigger breakouts. However, dairy is not the only cause of acne, and other factors such as genetics and diet can also contribute.
In addition to cheese and other dairy products, foods that are high in iodine, such as shrimp and seaweed, can irritate the skin and cause inflammation, making acne worse. Other acne-causing foods include sugar, fried foods, chocolate, nuts, and highly processed foods.
Yes, a balanced diet with plenty of fruits and vegetables can help provide the skin with essential nutrients to heal pimples. Oily fish such as salmon and tuna are rich in omega-3 fatty acids, which help fight inflammation in the body and keep acne at bay. Walnuts are also a good source of omega-3.
Whey protein has been shown to raise insulin levels, which can worsen acne. While there is a suggested link between whey protein supplements and acne, more research is needed to establish a direct cause-and-effect relationship.
If you are hesitant to cut out cheese and dairy from your diet, you can try making some changes to your consumption habits. For example, switching from skim milk to whole milk may help reduce breakouts. Additionally, cutting back on the overall amount of dairy you consume may be beneficial, as some studies suggest that milk aggravates acne only when consumed in large quantities.
