Is there a way to get rid of freckles?

I originally didn't have any blemishes on my skin, but I neglected sun care a bit because I was wearing a mask during the COVID pandemic.

Even when my friends worried about freckles or blemishes, I thought it was a problem far removed from me... ㅠㅠ

Since I haven't been diligently applying sunscreen since the pandemic, I suddenly started seeing spots resembling melasma on areas not covered by my mask. People around me say that melasma doesn't go away; is there really no way to treat it?

I'm curious to know what treatments those who saw good results from melasma and blemish treatments at a dermatology clinic received.
