Could you tell me some home care tips?

I was taking a selfie at a sunny cafe during lunch today and was shocked. Seeing it in natural light, my uneven skin tone and dullness were so obvious that I spent a long time staring in the mirror. Since I didn't have the time or money to go to a salon, I decided to try home care. I tried a few popular face masks and essences, but I'm not sure if they're enough. Do you have any special routines or home care recommendations? Honestly, even when I follow along on YouTube, I'm never sure if they're right for my skin type. Rather than buying expensive equipment, I'd recommend a home care routine that truly plumps up my skin from the inside out. How can I start and maintain this approach most effectively?
