Kidney problems can show up in the skin, showing how important kidney health is for our skin. Our kidneys filter waste, balance electrolytes, and keep acid-base levels right. If they can’t do this, toxins build up, affecting our skin.

Also, kidney problems can change skin color and tone. Kidney disease yellow skin is when skin turns yellow due to urochrome pigments. This is a sign of kidney trouble.
