Health functional foods

Last weekend, I met up with some old high school friends I hadn't seen in ages. I was excited, but as I looked at my friends' faces in the brightly lit cafe, I noticed I looked particularly dull and tired, which made me a little concerned. One friend had a particularly clear and vibrant complexion, so I asked her what her secret was. She said she consistently takes a health supplement that's specifically tailored to her skin. Honestly, I've always used the laziness as an excuse to skip taking supplements. But now that I look in the mirror, I'm starting to see that I don't look the same, so I'm starting to think I need to start taking better care of myself. Everyone around me has recommended health supplements, but there are so many to choose from, it's been difficult to choose. Perhaps because of the seasonal change, my makeup doesn't stick well and my skin looks dull, which is making me even more concerned. I'm curious about how you choose health supplements. Are there any skincare routines or products that have been most effective for you since you entered your 40s?
