I'm curious about the secret to regaining my lost radiant skin.

Lately, when I wake up in the morning and look in the mirror, my complexion looks noticeably duller than before, so I find myself staring at it for a long time. In the past, I used to have a subtle glow all over my face without even needing to use expensive cosmetics. Now, no matter what skincare products I apply, it feels like the moisture evaporates immediately, so I’ve actually become a little afraid to look in the mirror. Talking with friends and acquaintances, I see that everyone is deeply concerned about their complexion, making me realize that it is truly time to start taking care of my skin. I am trying to drink plenty of water and take vitamins to regain that clear, radiant glow, but it seems it isn't enough to see a dramatic change. Even when I try to cover it up with makeup, it only produces an artificial shine; I can't achieve the natural, healthy glow I've been hoping for, and it is a huge source of worry for me. By any chance, what products do you usually use to achieve glowing skin, or how do you maintain vitality through your daily habits?
