My facial shading is getting worse. Should I use a freckle ampoule?

I have a question.
I am a busy office worker, so it is very difficult for me to set aside time to consistently take care of my skin.
Especially this summer, perhaps because of the strong sunlight, the existing freckles seem to have gotten noticeably worse and spread wider.
I considered professional methods such as treatment, but it is realistically difficult to make time to receive treatment or start professional management right away because of my daily life.

So, first, I'm going to try a product that can be easily managed at home, such as a freckle ampoule.

My skin is not sensitive,
I am looking for a freckle ampoule that is effective in improving freckles and blemishes.
I wonder if there is a melasma ampoule that suits these conditions.

Please let me know if there is a melasma ampoule product recommended by Maypure that can be used consistently by busy office workers and is effective for melasma that worsens in the summer.
Or, if you could also share some simple home care tips that would be great to use alongside the freckle ampoule at home, that would be greatly appreciated.
