Teachers are a special profession, almost every day to contact chalk, plus after class to use alkaline soap or hand sanitizer to wash away chalk dust, after washing hands if not pay attention to skin care, the skin is easy to dry and cracked. Especially in winter, when the climate is dry, the sebaceous and sweat glands on the skin secrete less and lose moisture faster, so teachers’ hands are more likely to crack. It is best for teachers to be aware of hand care and prevent cracked hands through daily protection. First, try to use less strong alkaline soap, medicinal soap or detergent to wash your hands, and apply hand cream, such as vitamin E cream, petroleum jelly, olive oil, etc., after washing your hands to keep your skin moist. Secondly, rub your hands often and pay attention to keeping your hands warm in winter. Third, eat more carrots and green leafy vegetables, beans, etc. containing vitamin A. Properly eat more fatty and sugary foods, as well as prohibit smoking, quit drinking alcohol, eat less spicy foods, drink less coffee, strong tea, etc., can also increase the secretion of sebaceous glands and reduce dry and chapped skin. If your hands are already chapped, we recommend you to buy urea ointment, urea grease and 5%~10% salicylic acid ointment at the hospital or pharmacy to apply on the affected area. You can also use vitamin E pills for treatment: every time after washing your hands, use a needle to make a hole in the vitamin E pills, squeeze out the oil and apply it to the affected area, and you can see the effect after a few days. Rubbing it often after healing can reduce the chance of re-chafing.
