What ingredient is commonly found in exfoliating scrubs?

Exfoliating scrubs are designed to remove dead skin cells and promote a smoother, brighter complexion. All the ingredients mentioned contribute to this purpose in different ways.

Salicylic acid is a beta-hydroxy acid that helps to clear away dead skin cells and unclog pores, making it especially beneficial for acne-prone skin. Glycolic acid, an alpha-hydroxy acid, also aids in exfoliation by dissolving the bonds that hold dead skin cells to the surface, thereby revealing healthier skin underneath.

Microbeads, although increasingly scrutinized for their environmental impact, have been used in the past as physical exfoliants that provide a scrubbing action to remove dead skin.

Because each of these ingredients serves a specific and effective role in the exfoliation process, it makes sense that the answer would be all of the above, as they can all be commonly found in various formulations of exfoliating scrubs.
