Ingredients associated with blackheads

A blackhead is sebum that has collected in a pore and darkened as it oxidized in air. It is not dirt, and harder washing does not wash it away. This page makes no promise about blackheads; it lists products by what their ingredient list contains. It surfaces BHA toners and BHA serums in which salicylic acid or betaine salicylate is among the first three ingredients on the list, water not counted. An ingredient list is declared in descending order of concentration, so the position says how much of the acid there is relative to the other ingredients. Oil-soluble chemical exfoliation is the ingredient group most often associated with blackheads, and toners and serums are the formats people most often associate it with here. Other BHA products, with less of the acid, are not on this page, and neither are the cleansers, masks, exfoliants and moisturizers the same acid is in; every one of them is on the ingredient page.
