I want to improve my skin texture with practical home care methods.

One morning, I looked in the mirror and it occurred to me that I really needed to start taking better care of my skin. While going to a salon for a treatment would be the fastest way, it's also a burden in terms of time and money, so I've always resorted to home care.

However, I've been using the methods I've been using so far, and they haven't been very effective, perhaps because they don't suit my skin type. So, I'm thinking about completely changing my routine. There are so many devices and packs on the market, and I'm having a hard time deciding which ones will effectively improve my skin condition. Do you have any home care methods that are cost-effective and produce noticeable changes? Tips that I can consistently implement every day would be better than fancy equipment. Especially in these days of drastic temperature fluctuations, if you have any home care methods that simultaneously maintain moisture and elasticity, please share them. Even small habits are fine, so I'd appreciate your advice.
