Anyone applying loose or pressed setting powder — for a personal makeup routine or in a salon/makeup-artist setting where a soft puff is preferred over a brush.

A puff presses powder onto skin rather than dragging it the way a brush can, laying down a more even layer of loose or pressed powder — and because it's washable, there's no fresh disposable to toss out after each use.

Press the puff into loose or pressed powder, then tap off the excess before applying. Press and roll it gently over the skin rather than rubbing, which helps the powder set evenly. Wash it periodically with mild soap and water, squeeze out (don't wring) the excess water, and let it air dry fully before using it again.

Being reusable and washable, they cost less over time than disposable sponges, and having two in the pack means one can be in the wash while the other is in use. On the other hand, they only come in one color and one general size, so anyone needing a specific puff diameter for a particular compact should check the fit before buying.
