Removing skin blemishes and freckles

Since COVID-19, I've noticed a lot more blemishes on my skin.

Freckles, melasma, and other spots have appeared mostly around the cheeks..ㅠㅠ

My skin itself is good, and I often hear that my skin is good.

I'm very concerned about the blemishes.

So, I want to get blemish removal surgery. Which dermatology clinic should I choose?

What are some good devices that are widely used these days?

I'm curious about how much it costs.
