Skin
Organ / systemThe body's largest organ and outer barrier — and a visible record of some toxic exposures.
What toxicants do here
Arsenic produces characteristic skin changes and raises skin-cancer risk; dioxins can cause chloracne; nickel and chromium are common contact irritants.
What targets it — tap to learn each one
Chloracne and porphyria cutanea tarda are Agent Orange presumptives; arsenic is linked to skin cancer.
Persistent skin changes can signal a deeper exposure and, with arsenic, raised cancer risk — worth a clinician's eye.
Bring this to your clinician and your VSO — they decide what testing and care, if any, is right for you. For general, whole-person ways to support your body, see Whole health.
