My bank account is empty since morning... Will my skin investment this winter be successful?

It's 8 a.m. before work, and I'm already feeling a heavy heart... Standing in front of the mirror, the first thing I notice is my face, swollen from the cold wind. Looking back at my purchase history, I was so excited by the Olive Young sale the day before yesterday that I piled a bunch of stuff into my cart. I wonder why I did that. But now that I'm in my 40s, I've definitely reached a point where just applying things on the outside is limiting. My skin is so dry that my makeup keeps flaking and my complexion looks dull, so I decided to take a leap of faith and buy a bunch of inner beauty products. I've changed everything from health supplements to multivitamins to address my skin concerns. Perhaps because I'm a bit timid, seeing my bank balance drop makes my hands tremble a little... But what can I do? I think I need to start building up from the inside out to be able to endure the harsh winter weather. Today, I'm going to start by eating the things I brought and record the changes. If I stick to it for a week, can I expect to see a slightly clearer look? My wallet may be thinner, but I desperately wish my skin's texture would become firmer again. This winter, the winds have been particularly harsh and dry, so I find myself meticulously observing my skin's changing state each day. I wonder how everyone is managing their skin this winter... I hope my choice wasn't wrong.
