The main reason for white flakes on the legs is that the skin on the legs is thinner and has poorer nutrient metabolism. If the weather is drier, coupled with irregularities such as mental factors and dietary stimulation, it is also possible to increase the generation of dander. For patients with increased white flakes, it is necessary to strengthen the nutrition of the skin, and you can apply local ointments containing vitamin E or vitamin A appropriately to restore the barrier function of the skin and carry out proper moisturization. Also, appropriate vitamins and minerals can be taken. In addition, excessive scratching and other stimulation of the skin should be avoided in order to effectively prevent the continued increase of white flakes.
