Key Takeaways
- Low glycemic index diets can improve acne.
- Milk consumption, particularly skim milk, may worsen acne.
- Probiotics may have a potential role in acne treatment.
- Role of Diet and Supplements in Acne
- Evidence from Populations with Low Acne Incidence
Studies have shown that populations in Papua New Guinea and Paraguay who consume diets devoid of processed, high-glycemic foods have no acne. This highlights the potential impact of diet on acne incidence.
Impact of High Glycemic Foods on Acne
High glycemic foods can lead to a rise in blood sugar and subsequent release of insulin, which can contribute to acne pathogenesis by driving oil production in the skin and contributing to the proliferation of skin cells within the pores. Studies have shown that low glycemic index diets can improve acne, with diets like the South Beach and Mediterranean diets being effective.
Insulin and Acne Connection
Insulin resistance can lead to high levels of insulin, which can contribute to acne pathogenesis. Insulin and insulin-like growth factor can drive oil production in the skin and contribute to clogged pores. Avoiding high glycemic foods and consuming minimally processed foods can be helpful in preventing insulin resistance and improving acne.

Studies on Low Glycemic Index Diets
Studies have shown that low glycemic index diets like the South Beach and Mediterranean diets can improve acne incidence. However, these studies have limitations as it can be difficult to assess whether the outcome is due to the low glycemic index or other factors like weight loss and improvements in blood lipid panel. Nonetheless, avoiding processed foods, fast food, sugary cereals, candies, cookies, and pastries can be beneficial in improving acne.
In addition to diet modifications, studies have also shown a potential correlation between milk consumption and worsening acne, particularly with skim milk consumption. Whey protein supplements have also been linked to tough cases of acne. Probiotics can be helpful in modulating the skin and gut microbiome, which can impact acne incidence.
Specific Diets and Their Effects
South Beach and Mediterranean Diets
Studies have shown that low glycemic index diets can lead to improvements in acne. The South Beach and Mediterranean diets are two specific diets that have been examined in acne studies and are low glycemic index diets. Both diets largely focus on whole plant foods, meats, fish in moderation, and some dairy. Foods that should be avoided in these diets include processed foods, fast food, processed sugary cereals, candies, cookies, and pastries.
Processed Foods and Acne
Populations in Papua New Guinea and Paraguay consume a diet that is rich in whole foods and devoid of processed, high sugary, high glycemic foods. These populations have no acne, which suggests that a diet that has minimally processed foods can help in reducing acne. Processed foods, packaged foods, and fast food should be avoided as much as possible as they are high in sugar and can lead to high levels of insulin, which can contribute to the proliferation of skin cells within the pores, leading to clogged pores and acne.
Whole Foods Plant-Based Diet Considerations
Consuming largely whole foods plant-based vegan diet can be helpful in improving acne, but there is not enough data to suggest that excluding animal products is necessary. It is important to note that a vegan diet that is high in processed foods, packaged fake vegan alternatives, and alternative meats can have a high glycemic load, which can contribute to the persistence of acne.
Dairy Consumption
Studies have shown that milk consumption, specifically skim milk, is correlated with difficult cases of acne and worsening cases of acne in young males. The association between milk consumption and acne is not definitive, but plausible explanations include the processing of milk to remove the fat rendering whatever is in milk that could contribute to acne more potent, or skim milk not being as filling as whole milk leading to larger volumes of consumption. In addition to milk, whey protein supplements have also been linked to the development of tough cases of acne. There is no data to suggest that other dairy products, such as cheese or yogurt, are correlated with acne.
Probiotics
Resident microbes, or bacteria, in the skin and gut are important for skin and gut barrier function. Probiotics, or live bacteria, have been shown to help modulate the immune system and improve skin health. However, more research is needed to determine the specific strains of probiotics that are beneficial for acne.

Dairy Consumption and Acne
Correlation Between Milk and Acne
Several studies have shown a correlation between milk consumption and acne. Specifically, consumption of skim milk is associated with more stubborn cases of acne in young males. However, the association was not demonstrated in those who consumed whole milk and reduced-fat milk. It is not entirely clear what component of milk is contributing to acne, but some possible explanations include the processing of milk to remove fat, the larger volume of skim milk consumed, or the presence of hormones in milk.
Skim Milk and Acne Severity
Studies have shown that consumption of skim milk is associated with more severe cases of acne in young males. The reason for this association is not entirely clear, but one possible explanation is that something in the processing of milk to remove fat renders whatever is in milk that could contribute to acne more potent.
Hormones in Milk and Their Effects
Some people speculate that the hormones in milk, specifically cow hormones, may be contributing to acne. However, others suggest that skim milk has fewer estrogen cow hormones, which may counterbalance some of the adverse effects of the male cow hormones in the milk. It is not entirely clear what component of milk is contributing to acne, but several studies have shown a correlation between milk consumption and acne.

Supplements' Impact on Acne
Whey Protein and Insulin Response
Studies have shown that insulin and insulin-like growth factor play a significant role in the development of acne. These hormones contribute to oil production in the skin, leading to clogged pores and acne. Foods with a high glycemic index and load can cause a spike in insulin levels, making it important to avoid such foods.
Low glycemic index diets have been found to improve acne in several studies. The South Beach diet and the Mediterranean diet, which focus on whole plant foods, meats, fish in moderation, and some dairy, have been examined in acne studies and found to be low glycemic index diets. It is important to avoid processed foods, fast food, processed sugary cereals, candies, cookies, and pastries as they are high in sugar and can lead to a rise in insulin levels.
Dairy consumption has also been linked to acne, with milk consumption being correlated with difficult cases of acne in young males. Skim milk consumption, in particular, has been associated with stubborn cases of acne. However, it is unclear why this is the case. One plausible explanation is that something in the processing of milk to remove the fat somehow renders whatever it is in milk that could be contributing to acne more potent. Another potential explanation is that skim milk is not as filling as whole milk, leading to larger volumes of consumption.
Whey protein supplements, which are 20% cow's milk, have also been linked to the development of tough cases of acne in some case reports. It is important to take away from high processed sugary foods and milk consumption to avoid worsening acne.
Probiotics have also been found to play a role in acne. The natural microflora in our skin and gut are important for maintaining a healthy skin barrier and gut barrier. These microbes release factors that help modulate the immune system and prevent inflammation. Further research is needed to determine the exact role of probiotics in acne.
Role of Probiotics in Acne
Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit to the host. The use of probiotics has been gaining popularity as a potential treatment for acne.
Studies have shown that probiotics can help improve the skin's barrier function and reduce inflammation, both of which are important factors in the development of acne. Probiotics work by restoring the balance of bacteria in the gut and on the skin, which can become disrupted due to factors such as diet, stress, and antibiotic use.
One study found that a probiotic supplement containing Lactobacillus acidophilus and Bifidobacterium bifidum significantly reduced the severity of acne in participants after 12 weeks of use. Another study found that a topical probiotic containing Lactobacillus fermentum improved acne symptoms and reduced the number of acne lesions.

While more research is needed to fully understand the role of probiotics in acne, they show promise as a safe and natural treatment option. It is important to note that not all probiotics are created equal, and the specific strains and doses used in studies may vary. Consultation with a healthcare professional is recommended before starting any probiotic regimen.
