I was shocked when I saw the photos I took recently, so I'm thinking about starting to take care of myself. Could you recommend some health functional foods?

Hello! How's everyone doing today? I was really surprised when I looked at the photos I took with my friends yesterday. I thought I was diligent about applying basic skincare and taking care of myself, but among my friends, I looked particularly dull and tired. I wondered if it was the lighting, but when I looked closely in the mirror, I could see my skin had lost elasticity and become sagging from the inside out, which was really disappointing. So now I realize that applying skincare alone won't cut it, so I'm trying to consistently take at least one proper health supplement for inner beauty. I wasn't really interested in this before, but the changes I've noticed over the years are undeniable. Do you have any specific health supplements you take for your skin tone or overall vitality? With so many products on the market, it's hard to know which ingredients to prioritize. If you have any health supplements you've personally tried and found really good, could you share them with me? I'll be waiting for your valuable tips!
