There is a difference between infantile acne and eczema in that the cause of the disease is different, the appearance of the form is different, and the location of the disease is different. Infantile acne may be caused by excess androgens in the mother’s body, which are passed to the fetus through the placenta. When the fetus is delivered, the excess androgens stimulate the sebaceous glands of the hair follicles to form a cortex, and acne is formed when there is a blockage of the excretion to the cortex. The lesions of infantile acne begin as scattered, single skin rashes with small white tips on top of the rashes. The causes of infantile eczema are more varied. Infants’ skin is relatively thin and tender, and can be triggered by allergic factors such as sunlight, ultraviolet rays, cold, excessive sweating, pollen, shrimps and crabs. The main manifestation of infant eczema is a small red rash with no other substances in it. Infant acne is usually concentrated on the child’s face, forehead, chin and these locations, growing more on the face. Baby eczema is more common on the trunk of the child’s body, on the extremities, or in the folds of the skin. There are other differences between baby acne and eczema, so go to the hospital and let a medical professional determine the specifics, and do not self-medicate.
