I'm worried about health functional foods because my complexion doesn't look good, maybe because it's the changing of seasons.

Last weekend, I went to an exhibition with friends. Looking at a group photo I took after a long time, I was shocked at how exhausted I looked. I thought I was well-rested, but I noticed a dullness that even makeup couldn't hide. Now, I'm realizing that taking care of the inside is just as important as what I put on the outside, so I've been diligently researching health functional foods. But there are so many different types, it's hard to know where to start. What health functional foods will definitely brighten your complexion if you take them consistently? Are there any health functional foods that everyone carries in their bag? If so, could you kindly recommend them?
