[Question & Concern] How to recover skin that has been heavily exposed to the sun~

I went on vacation last month.

Maybe it's because I swam all day under the sunlight.

I rode a lot,ㅠㅠ

I applied sunscreen to the exposed areas before swimming on the same day.

Knowing that it was made like this, I used aloe gel type.

They kept changing it and also lowered the fever.

It's been almost a month now.

It has improved a lot, but there is still a mark remaining.

Right now, the part I am most concerned about is my calves.

The school uniform is shorts.

I keep checking myself in the mirror every time I go to schoolㅠㅠ

How should I adjust the skin tone in this condition?

Do you know a good method or not?

Please advise those with experience~~
