which fruit juice is good for skin whitening - #24648

I am seriously trying to figure out which fruit juice is good for skin whitening. A few months back, I started noticing some dark spots and overall dullness in my skin, super frustrating! I've tried lots of creams, but they haven't really worked well. A friend mentioned that certain fruit juices could help brighten up skin tone, and I got really curious. Is there any specific juice that has worked for others, like, does lemon juice actually help? I've heard papaya juice is great too, but honestly, I'm not sure how to incorporate it into my diet. What about drinking juice vs. applying it topically? I'm also little doubtful if these juices could cause any reaction, since my skin can be sensitive. If you guys have personal experiences or know of any studies about which fruit juice is good for skin whitening, that’d be super helpful. I’m just looking for something natural and effective, you know? Thanks a bunch!
