They can whiten because they are rich in VC, but many fruits are photosensitive plants, which means that eating them during the day may be counterproductive.

I suggest eating fruit every day, and don't think too much, because people consume about 200g of VC every day, so relying solely on fruits and vegetables can't meet the standard.

If you want to whiten, it is recommended to do a good job of sun protection and then use some supplements. Grape seed extract, VC, VE (descending order), etc. These are very good whitening and antioxidant products, but we should stick to them.
