For many adults, acne is a persistent issue that doesnβt disappear after the teenage years. Frequent breakouts can be frustrating and affect self-esteem, leaving many to wonder why the problem continues into adulthood. Despite trying countless skincare routines, the lesions persist, especially for women, who are more likely to experience adult acne. Itβs a struggle that impacts both confidence and quality of life.
In 2020, a large cross-sectional study was conducted as part of the NutriNet-SantΓ© cohort study in France and published in JAMA Dermatology. This study enlisted French adults to explore the potential link between diet and adult acne. Its findings offer new insights into how everyday food choices may influence skin health.Β However, itβs important to note that these findings are observational and not definitive.

The Study At A Glance
This study aimed to explore how diet might be associated with adult acne, providing evidence on whether specific foods contribute to breakouts. With nearly half of adults continuing to experience acne, a large percentage of which are women, the research sought to determine the role of food choices in this issue.
The study followed 24,452 French adults, 75% of whom were women, with an average age of 57. Participants reported their acne status as never, past, or current and provided details on their diets, medical history, lifestyle, and underlying conditions. This diverse group allowed for a broad analysis of how diet and other factors might be linked to acne.
Researchers collected detailed 24-hour dietary records, categorizing food intake into 12 groups, such as fruits, vegetables, dairy, and fatty foods. This approach gave a comprehensive view of dietary habits and allowed for the analysis of broad patterns rather than individual foods. Statistical methods like principal component analysis identified key dietary trends that appeared to be linked to acne.
To ensure accuracy, the study controlled for confounding factors like age and physical activity, with special attention to hormonal factors in women. This careful approach made the study one of the most comprehensive on diet and acne, offering valuable potential insights into how dietary patterns may affect skin health.
Key Findings
The study found that adults with acne were more likely to consume milk, sugary beverages, and fatty, sugary foods compared to those with clearer skin. These dietary patterns appeared to be linked to acne, even when the researchers accounted for factors like age, smoking habits, and physical activity.
Specifically, milk and sugary beverages, such as soft drinks and sweetened drinks, were associated with higher odds of adult acne. Participants who consumed these items more frequently were more prone to experience ongoing breakouts, suggesting that these foods may contribute to acne development.
Additionally, diets high in fatty and sugary foods, such as processed snacks and fast food, were also closely linked to acne. The study identified a pattern in which excessive sugar, fat, and dairy consumption was correlated with more frequent breakouts in adults.
Significance of the Findings
The study provides observational data suggesting a link between diet, particularly milk, sugary beverages, and fatty foods, and adult acne. Since adult acne can impact quality of life, these findings highlight the possible role of food choices in skin health. This large-scale research supports the idea that the Western diet, high in processed and fatty foods, may be a contributing factor in adult acne development.
The study also shows that high glycemic load foods, which raise blood sugar quickly, could be associated with increased inflammation and triggering hormonal changes that may boost oil production in the skin. This large cohort study offers important insights compared to smaller previous studies that hinted at the same connection.
The findings suggest that dietary changes, like reducing dairy, sugary drinks, and processed foods, might help support the management of adult acne. This research provides a foundation for further exploration into diet-based acne prevention and treatment strategies, offering one potential approach alongside traditional treatments.
How The Findings Can Be Implemented
The study suggests that adults with acne may benefit from reducing their intake of milk, sugary beverages, and fatty foods while increasing their intake of fruits, vegetables, and fish, which are believed to have anti-inflammatory benefits and may support healthier skin.
Healthcare providers might consider integrating dietary advice into acne management plans, and public health campaigns could raise awareness about how certain food choices may be linked to skin health. Further research could refine these recommendations and influence future acne management guidelines.
Limitations of the Study
A significant limitation is the reliance on self-reported data for diet and acne status, which may lead to inaccuracies, as participants might misremember or misreport their diet or skin condition. This recall bias can affect the data's reliability, especially when tracking patterns over time. Additionally, self-assessed acne severity may not match clinical diagnoses, leading to potential misclassification.
The study shows a correlation, not causation, between diet and acne. While it suggests a potential link between certain diets and acne, it doesn't prove that reducing specific foods will prevent or lessen acne. Randomized controlled trials (RCTs) are needed to confirm a cause-and-effect relationship. Although the study controlled for factors like age and lifestyle, hormonal influences could still affect the results, especially in women. Further research is needed to clarify these findings.

Key Takeaways
- The study found a potential link between milk, sugary beverages, fatty foods, and adult acne. Reducing these foods might help support skin health through dietary changes.
- Increasing the intake of fruits, vegetables, and fish, which are thought to support lower inflammation, may contribute to clearer skin when regularly included in the diet. Healthcare professionals might consider offering dietary advice as part of an overall acne management plan, and public health efforts could encourage healthier eating based on these insights.
- While the findings suggest a possible connection between diet and acne, more research is needed to confirm if dietary changes can effectively support clearer skin.
