Astaxanthin for Hyperpigmentation: Paracrine Signal Interruption, MSK1 Blockade, and What the Clinical Evidence Actually Supports (2026 Research Review)
Astaxanthin acts upstream of tyrosinase, blocking UVB-driven keratinocyte cytokine signalling and the p38/MSK1/CREB/MITF axis. A critical review of the mechanism and the human evidence.
Azelaic Acid for Hyperpigmentation: Multi-Pathway Inhibition, Clinical Evidence, and 2026 Formulation Science
Azelaic acid operates through four distinct biochemical pathways — tyrosinase inhibition, TRP downregulation, anti-inflammatory action, and PPAR-gamma agonism — making it one of the most comprehensively effective depigmenting agents. Clinical evidence supports its use in melasma, post-inflammatory hyperpigmentation, and uneven skin tone.
