Severely dry lips

I have suffered from severely dry lips for as long as I could remember, my earliest memories consist of me picking at my lips and always having dead skin on them and bleeding, I have tried literally EVERYTHING I’ve been recommended by friends families and doctors and I can’t find anything that helps, I’ve considered lip fillers just because I heard they can smooth out your lips more and keep them more moisturized but I am not in the right place financially right at the moment to spend like 600+ dollars on them, PLEASE any recommendations of lip products that can help would be very very much appreciated I am willing to try anything, thank you!! ❤️
