If there is one balm I would buy over and over, it would the Smith's Mentol tin.
This is the most effective multi use balm I've ever used! For lips, for dry patches, for smoothing out chapped/dry lips... this tin kind of does it all.
I have been using this for many years, and mostly in the evenings. The tin isn't the most practical, but I use it primarily before i sleep with clean fingers so it's okay. There is something so nostalgic about the tin. I seriously seriously love this stuff.
It absorbs quickly, and keeps my lips smooth. It works best overnight because the next morning my lips feel super soft and lipstick ready for the day.
I have also used this as a 10 minute intensive treatment for my lips by slathering a good amount on my lips while doing my hair or makeup, then wipe all of it off my lips before applying lipstick.
Another skincare product I've been using for months is this collagen serum from Leaders, a Korean brand that's sold in Asian skincare stores. I couldn't find much about it on the web here, but I've been using it and have repurchased a 2nd bottle already. Seems like it's strictly collagen, watery based. Has a nice subtle scent, and very easily absorbed into the skin.
