How to effectively remove summer stains?

Thank you for your hard work

I applaud those who worked hard this summer like me.
I thought I was paying attention to sun care, but I guess there were limits.
Because of this 'medal'-like freckle that gets darker every time I look in the mirror, my skin tone is as dark as the freckle color.
It seems like the traces of suffering under the strong sunlight are clearly visible on my face and skin.

In particular, I am planning to start removing freckles from now on because the freckles that have appeared on my face do not go away.
I'm asking this question because I want to know about effective methods for removing freckles, as well as any possible side effects or precautions.

1. What are some effective ways to remove freckles?
2. If there are any home care products or ingredients that are effective, please recommend them.
3. I would like to know if the medication I am taking helps remove freckles and if there are any side effects.
4. I've heard that sun protection is important. Besides applying sunscreen after the procedure or during treatment, are there any special precautions I should take?

Please help me win the war to remove freckles!
