Please help me out with my clumsy hands ㅠㅠ Do you have any great home care tips that I can pull off easily all by myself?

Hello everyone!! Prices have been rising so much lately, and my wallet just can't keep buying memberships at aesthetics clinics or salons, so I've decided to become a home care enthusiast and take care of myself at home haha. But now that I'm actually trying to confidently get started, I feel completely lost on where to begin and how to do it, so I've come here to ask for some help from you all!! If you have any amazing home care tips that you're quietly keeping to yourself, please discreetly share them with me too hehe.

I've actually stayed up all night for days watching videos from skincare experts on YouTube and Instagram. I saw some people mixing modeling masks with toner or ampoules instead of water, and others using saline solution masks to instantly reduce redness. Since I have such clumsy hands, I'm worried I won't be able to do it well on my own without spilling anything. I've heard that getting the water ratio right is especially difficult with modeling masks. Does anyone happen to know any home care tips for mixing it perfectly to get a nice, sticky consistency without failing the first time?

And these days, beauty devices come out in such a wide variety and are quite expensive, you know~ I'm curious if those of you who use devices like galvanic or radio frequency really feel a noticeable difference in your skin condition the next morning compared to when you just pat products on with your hands!! I haven't been able to bring myself to buy it right away because I'm afraid it will just end up gathering dust in the corner of my vanity, so I've just kept it in my cart haha. If you have any home care tips on how to make the most of the device and get my money's worth, please give me some honest advice!!

If you know any amazing home care tips on how to achieve salon-quality, radiant skin using only ingredients found at home or basic products, without spending a fortune, please share them in the comments! It doesn't have to be anything fancy; even small habits like getting the water temperature just right when washing your face are great!! I'll be eagerly waiting for your expert home care tips haha.
