How often should I wash a cushion puff?

I use it every time I do my makeup, but suddenly I started worrying about the hygiene of the puff.

I've been using the puff continuously until I finished the cushion.

I thought it would be fine as long as I wiped off the foundation on the surface with a tissue from time to time, but recently I saw a post saying that a lot of cosmetic residue and sebum remains on the puff more than I thought.

Come to think of it, since I pat my clean face with the same puff every day, I wondered if the skin trouble I was getting might be because of this.

However, washing it every day isn't realistically easy, and I'm worried the puff will get damaged quickly if I wash it too often, so I'm not sure what the appropriate washing interval is.

I'm also wondering if once a week is enough, or if it's better to wash it every few days.

Also, I heard that you should use a washed puff after it has been completely dried, but I think it would actually feel more unpleasant if it isn't dried properly.

Has anyone seen a reduction in skin trouble after starting to wash their puffs frequently?

Conversely, I am curious if you are using it without any problems even if you only wash it once in a while when you remember, like I do.

Maybe it's because it's a beauty tool I use every day, but I'm suddenly really curious about how other people take care of it.
