Please tell me how to treat freckles

Hello. I would like to inquire about treatment for freckles.

I have a lot of freckles on my face, so I always have a complex about it.

It's annoying when taking pictures, and on days when I don't wear makeup, I feel reluctant to meet people face to face.

I think I need to get treatment for my freckles. What are some treatments available?

Also, I'm curious about what I should be careful about after receiving treatment for freckles and how long it will last.

I heard that even if I get treatment, it doesn't completely disappear and there's a high chance of recurrence. Is that true?
