Is it right to take health functional foods during this seasonal transition period?

The season of cold winds has arrived. The other day, I stopped by a department store and was startled by my face under the bright lights. The wrinkles around my eyes seemed deeper, and my complexion looked so dull that I spent a long time staring in the mirror. I considered changing my cosmetics, but I could feel my fundamental stamina and nutrition weren't what they used to be. So, I decided to properly research and consume health functional foods, as everyone talks about. In the past, I dismissed them as a virtue, saying food is medicine, but now, one by one, my friends are also taking at least one health functional food that suits them. I'm starting to reflect on myself a bit, wondering if I've been too complacent. I'm curious to know what health functional foods you typically take for skin vitality or fatigue recovery. Have you ever had a truly satisfying experience with regular intake?
