While milk doesn't directly cause acne, evidence suggests it may worsen breakouts for some individuals by potentially increasing sebum production and inflammation.
How Milk Might Affect Sebum Production
- Androgens and Inflammation: Cow's milk contains androgens, hormones that can stimulate sebum production. Increased sebum, combined with inflammation (also potentially triggered by dairy), can lead to clogged pores and acne.

- Insulin Levels: Some studies link dairy consumption to increased insulin levels, potentially worsening acne severity. [Source: Healthline, Jan 24, 2018].
- No Direct Causation: It's crucial to note that no single food directly "causes" acne. However, dairy may be a contributing factor for some people, increasing the risk of developing acne or worsening existing conditions.

- Conflicting Research: While studies show a correlation between dairy consumption and acne, research is ongoing, and results are not universally consistent. Some studies find a link, while others do not. [Source: AAD, NCBI Systematic Review and Meta-Analysis, Verywell Health].
Important Considerations:
- Individual responses to dairy vary greatly. What affects one person may not affect another.
- Other factors significantly influence acne, including genetics, hormones, and stress.
