Chocolate may briefly worsen acne in acne-prone people, but doesn’t cause it.

The Claim

Eating chocolate causes acne.

Verified by Lenz ·

The Short Version

The claim that "eating chocolate causes acne" significantly overstates the evidence. While several controlled studies show chocolate consumption can worsen acne in people who already have it, these findings are limited to acne-prone subgroups, involve short-term exacerbation rather than true causation, and may be confounded by sugar and dairy additives. The American Academy of Dermatology explicitly states research does not support claims that chocolate causes acne. The blanket causal claim is misleading.

Caveats

  • The supporting studies only tested acne-prone individuals and measured worsening of existing acne — not whether chocolate causes acne in people who don't already have it.
  • High-glycemic additives like sugar and dairy in chocolate products — not cocoa itself — may be the actual drivers of the observed effects.
  • The American Academy of Dermatology (2025) explicitly states that research does not support claims that specific foods like chocolate cause acne.
