I've tried, hydrocortisone cream and ointment, e45, beeswax, vaseline, cetaphil, epaderm, lemon on lips, do nothing method, exfoliation method and all possible diet changes. I know there's more, but this spans over a long time, so I can't remember all of it right now.
Right now it cycles around every 36 hours. The bottom lip was completely torn off (I'd had enough) when I took those pics, but within 2 days it'll be back looking like the top lip. The skin is usually white, which contrasts heavily against my skin tone, but hydrocortisone can in the very least, even out the colour :(
