Lightening keloid scars. Is skin whitening / skin bleaching cream a good option?

Hi everyone,

I have had laser treatments on my keloids and the pigment is not lifting at all. I am quite fair skinned but have yellow undertones and tan easily (my dad is olive skinned) so I try to stay out the sun so the keloids don't get darker. They are currently pink/light purple.

I was wondering if people could share their opinions on skin bleaching / lightening creams for lightening keloid pigment? I am currently looking at Caro White but there aren't many threads on this at all.

Opinions?

Thanks :)
