Please recommend a mild, non-irritating freckle care product.

I didn't have any freckles before, but at some point, I noticed a dark spot on my cheekbones and it spread to the surrounding area. I quickly searched and got recommendations for freckle care products, but since my skin is thin, some of them sting or irritate my skin. Especially recently, my skin condition has been deteriorating, so I think it gets irritated more easily. But I can't ignore these freckles. Could you recommend a mild freckle care product that is good for my thin and sensitive skin? If possible, it would be even better if you recommended a freckle care product that is not drying and has moderate moisturizing properties.
