afamelanotide (melanotan i) mastery course
Unit 4 of 12
EPP Pathophysiology and Light Toxicity
Why visible-light exposure becomes clinically central in protoporphyria.
The Disease Context
The afamelanotide story only becomes clinically coherent when EPP is treated as the central use case. This unit explains why light tolerance is not a cosmetic endpoint here.
Heme Pathway Basics
The metabolic pathway that frames the disorder.
Protoporphyrin Accumulation
Where the biochemical burden comes from.
Light Toxicity
Why visible light can trigger severe pain in EPP.
XLP and Overlap
Closely related disease framing and overlap logic.
Daily Life With EPP
How biology translates into lived clinical burden.
