Aluminium salts are primarily found in which type of cosmetic product?

Aluminium salts are commonly found in astringents due to their capacity to act as anti-inflammatory agents and their ability to help shrink tissues and reduce secretion. In cosmetics, astringents are used primarily for their skin-tightening properties and effectiveness in controlling oiliness, making them particularly beneficial for individuals with oily or acne-prone skin.

Aluminium salts function by forming a protective barrier on the skin that can help control excess oil and minimize the appearance of pores. This makes them valuable in formulations that aim to reduce shine and improve the overall texture of the skin. While aluminium salts may not be prominent in moisturizers, sunscreens, or serums, their role in astringents particularly highlights their benefits in products meant for toning and refreshing the skin.
