Deficiency of vitamin A will cause the epidermal columnar cells to turn into plate-like squamous cells, making the skin’s water-locking function worse, skin roughness, and making the skin appear ichthyotic and pimple-like keratotic abnormality symptoms.
Lack of vitamin A is easy to make the skin appear toad skin disease, manifested as the whole body skin dryness, the deep side of the limbs skin pores appear horn cone-shaped abnormal hyperplasia, accompanied by varying degrees of itching sensation. The above symptoms will be improved after appropriate vitamin A supplementation.
