[Question] What is the difference in ingredients and effects between whitening injections and whitening injections?

My skin looks darker, maybe because it's summer, so I'm looking into various things.

Do whitening injections and jade injections help brighten skin tone? If anyone has tried them, I would like to know how they were.

I am also curious about the difference in ingredients between whitening injections and whitening injections, as well as the difference in their effects.

My skin is quite dry and has a somewhat dark tone. Which product would be more effective for this type of skin? Are there any factors I should consider when choosing?
