Kitchen DIY (lemon, baking soda, toothpaste)

Skip: The kitchen is not a labevidence: strongPEER-REVIEWED 2015

Lemon juice plus sunlight can cause a genuine burn-like reaction called phytophotodermatitis. It blisters, and it doesn't need you to be allergic. Baking soda and toothpaste are alkaline: your skin runs slightly acidic on purpose, and pushing its pH up weakens the barrier that keeps irritation and bacteria out. None of these treat pimples, and all of them can leave marks that outlast the pimple they were aimed at.

what the evidence says

Phototoxic citrus reactions are well documented in peer-reviewed literature; skin-pH research shows alkaline exposure degrades barrier function.
