I have finally found a solution for a problem that's been bothering me for quite a while.
I have very sensitive hands and while I apply hand creams all the time, no amount or any kind of regular hand cream could help with cracked fingertips. This particular problem started a few years ago, I even went to see my doctor about it but his advice was to just mositurize. Also, it was season-unrealted, I'd get cracks in summer or winter, usually on one or two fingers only. It would somehow resolve itself, after undefined amount of time and for no reason I could identify, but I was just happy the problem was gone. If you ever had this problem, you know just how difficult everyday activities can become due to endless discomfort in your fingers. And it sometimes made me feel uncomfortable and even embarrassed in public due to my fingers looking chapped and uncared for.
Well, a few days ago I stumbled across this article and long story short, I tried one advice from there - I applied tea tree oil to my fingertips. I love tea tree and use it for many things, and now it's firmly one of my all-time favorite natural remedies. In less than two days my skin had healed with no signs of it being prone to cracking again. I keep pressing my fingertips in expectation of the stinging or pain, so I can make a mental note which finger to be careful with, but there is nothing. To say I am elated is an understatement.
I just wanted to share this simple, but effective solution in hope it may be of help to someone else too. We often discuss skin care here on the forum, and for me looking after my hands is as high on the list of priorities as my facial regime.
