i was having dark and thickened spots in my finger skin for few months. now it’s started to crackle?
darn cracking skin on only the hands and finger joints can be caused simply by contact allergies or due to some habits like smoking or working a hard work job by using too little moisturizer or by frequent hand washing. however continued cracking deep fissures bleeding or no improvement with extra moisturizing may signify a more serious skin condition usually a type of eczema. i recommend you would see a dermatologist if using moisturizers and over the counter steriod creams fails.
