Wait, let me get this straight: they're not even sure if Yellow #5/Tartrazine is safe to be applied topically, but it's FDA-approved to be ingested?
Things absorbed through the skin may be in a different state when they reach your bloodstream than things that are ingested. The process of digestion can break down a lot of things that would otherwise be harmful, but aren't similarly filtered when absorbed through the skin.
It's also why some medicines are taken by swallowing a pill, and some are taken by dissolving a tablet under your tongue.
