How often is skin exfoliation recommended?

Hello, recently the weather has been hot, so impurities have been building up on my skin...

I'm thinking of getting a proper exfoliation treatment, so I was curious about the typical frequency and duration.

I usually used to exfoliate at home about twice a week.

I think getting it done at a dermatology clinic might be different, since the exfoliation effect is a bit more superior.

I think I could extend the exfoliation cycle a bit, though.

Also, I heard that exfoliating too often makes the skin sensitive....

I'm debating whether to get it done when I get bothered by dead skin cells every now and then.

Have you ever received separate exfoliation care at a dermatology clinic by any chance?

I'm curious if it will definitely be different.
