Mechanism

Inflammation

Innate immune response producing redness, swelling, and discomfort in affected skin.

Review

What it is

Inflammation in skin is driven by cytokines such as IL-1, IL-8, IL-17, and TNF-α, plus toll-like receptor signaling.

Both Cutibacterium acnes and Malassezia metabolites can activate these pathways and contribute to visible inflammatory features.

Reducing inflammatory signaling — without removing host immunity — is a shared treatment theme across many conditions.

Why it matters

Inflammation links microbes, sebum metabolites, and barrier disruption to the visible features users actually see and feel.
