Abstract: Acne is primarily an immune-mediated response to Neu5Gc (from red meat and dairy) and gluten (from wheat and related grains). Chronic immune activation leads to skin inflammation and acne as a visible manifestation of systemic immune processes.

Introduction

Acne vulgaris is traditionally attributed to excess sebum, follicular occlusion, bacterial colonization, and hormonal influences. However, these may be secondary effects of a deeper immune response triggered by dietary antigens. This page outlines a unifying theory linking all major forms of acne to exposure to Neu5Gc and gluten.

The Triggers

Neu5Gc

  • Found in bovine-derived food products (red meat, dairy).
  • Incorporated into human tissues despite being non-human.
  • Provokes anti-Neu5Gc antibody response in all humans (Varki et al., UCSD).
  • Repeated consumption leads to chronic inflammation.

Gluten

  • Present in wheat, barley, and rye.
  • Can increase intestinal permeability (“leaky gut”).
  • Triggers immune activation and systemic inflammation in susceptible individuals, even without celiac disease.

Pathophysiology: Acne as an Immune Expression

  1. Antigen exposure (Neu5Gc, gluten) → systemic immune recognition.
  2. Lymphatic involvement → node swelling, immune cell activation.
  3. Sebaceous gland stimulation → increased oil production.
  4. Follicular occlusion and bacterial colonization → comedone formation.
  5. Chronic inflammation → inflammatory lesions (papules, pustules, cysts).

Clinical Spectrum

Non-inflammatory acne

Comedones represent early lymphatic congestion.

Inflammatory acne

Nodules, cysts, and widespread lesions are linked to deeper lymph node activation.

Distribution Patterns

Lesion locations (face, chest, scalp, mucosal sites) follow lymphatic drainage and cytokine signaling pathways.

Immune Mechanisms

  • Antigen-presenting cells detect Neu5Gc/gluten.
  • Lymph nodes undergo hyperplasia and recruit inflammatory cells.
  • Activated T and B cells migrate to skin tissue via lymphatic and vascular pathways.
  • Lesions form according to predictable drainage and tissue tropism.

Conclusion

This theory reframes acne as a systemic immune disorder with visible cutaneous manifestations rather than a purely dermatological or hormonal problem. By identifying Neu5Gc and gluten as primary antigens, new therapeutic strategies may emerge for acne and related inflammatory diseases.
