Are there any effective freckle ampoules?

Lately, I've noticed that my skin is getting darker and darker, so I feel like I need to take better care of it. So, I've been looking into ampoules from various brands, but with so many options, I'm having a hard time deciding which one to choose.

I've been seeing a lot of Meladuse Brightening Ampoules lately, and I'm curious because some people who have actually used them say it's good for alleviating freckles.

Even among freckle ampoules, the ingredients vary, so I'd like to know which one is less irritating for sensitive skin. Will consistent use help even out skin tone or fade blemishes? Could you also recommend a freckle ampule that absorbs well and isn't sticky, something I can use morning and night?
