I'm looking into health functional foods because I don't look very lively in the mirror.

Last weekend, I attended a high school friend's wedding, a long-awaited event. The weather was great, and my friend was so pretty, so I took lots of photos in a good mood. I was shocked when I received the group photo later. I thought I'd covered it up with makeup, but under the bright outdoor light, my face looked completely lifeless. It suddenly occurred to me that perhaps just applying cosmetics on the outside wasn't enough. So, I've been looking into inner beauty and finding suitable health functional foods. In the past, taking these supplements felt like a chore, but seeing my skin's elasticity improve every day when I look in the mirror, I feel like they're not an option, but a necessity. I'm finally realizing the value of those health functional foods, which my friends have been recommending to me for a while now. With so many different types of products out there, I'm wondering which ingredients are best for me and which ones are easy to take regularly. What criteria do you use when choosing products? Have you experienced a clearer complexion or improved skin condition through consistent use?
