How to treat dry peeling skin on children's hands due to sweating

Patient's question:

Spring and autumn. Cracked and peeling hands

Doctor's answer:

It is recommended to apply external vitamin C injection to the affected area twice daily, with a three-day course of treatment. It has a good effect on the recovery of skin lesions.
Method: First, wash your hands thoroughly and let them dry slightly. Then, pour vitamin C injection into your palm. Rub the liquid evenly between both palms until it dries and turns white, then wash it off. Do this twice daily, with each application using two milliliters.
