[Recommendation Request] Do you have any cost-effective home care products?

Yesterday, I was looking in the mirror under the bathroom light and was shocked. My skin looked much duller and less hydrated than usual, which was frustrating. I have a close friend's wedding next month, so I need to start taking care of it, but going to the salon every time is a bit expensive. So, I've been looking for practical home care products that I can use regularly at home. I'm debating whether it would be better to switch up my basic products or buy a reputable beauty device. Honestly, I used to just use whatever I could, but now I'm really paying close attention to ingredients. Do you know of any home care products that are safe for sensitive skin? If you know of any inexpensive ones that work well, please let me know. How do you keep your skin in good condition these days?
