A serum that also provides moisturizing and whitening functions

Since it's winter, are there any serums that provide good hydration as a basic function while also having a brightening effect? ​​My skin is thin, so I haven't really reached for products with whitening properties because they seem to make my skin sensitive. However, as I get older, dullness is inevitable, so I guess I need to start paying attention to brightening benefits. If you know of any serums that offer both good hydration and brightening, please recommend them.

Happy New Year!
