How to Remove Freckles: Are Facial Pigmentation Treatments Effective?

Recently, as facial pigmentation has become more noticeable, interest in how to get rid of freckles has increased.

I feel like home care alone is limited, so I'm also considering getting a treatment to improve facial pigmentation.
Among the methods for removing freckles, I'm also curious to know whether treatments actually help and how to manage facial pigmentation to prevent it from recurring.
I'd like to hear advice from people who have experience with removing freckles and managing facial pigmentation.
