Chilmun) I keep looking at my palm, and it feels like the skin is cracking.

When I spread out my palms, the left and right sides are different. The left side is fine—I'm not sure if it's my dominant hand or the right—but when I spread my palm, the skin is cracked, and what looks like powder is flying around. I could understand if this happened to both hands, but it is specifically my right hand. I'm not sure if the skin is cracked and stiff, or if it's just dryness, but the skin keeps cracking, and there are these strange particles flying around, which is incredibly uncomfortable. I've tried applying hand creams and even medicinal hand creams from the pharmacy, but it hasn't improved much. Is this serious enough to require a visit to the hospital?
