What type of creams, surgeries, or home remedies can make freckles fade away or lessen in appearance?

Fading cream & sunsc: Fading cream, peels, & sunscreen.

Impossible: It's impossible to get rid of them.

I wouldn't do it: If you use a freckle remover, even from a dermatologist, you risk disfiguring yourself. Freckles are endearing, they're distinctively you, and a majority of your friends probably like them. Ask them. If you want them less prominent, avoid excess sunlight -- wise in any case.
