White pimples on the face of infants may be due to acne, milia, crystalline milia, etc. The specific analysis is as follows: 1. Infant acne: Infant acne is a relatively common benign problem of infant skin, which occurs in infants 3-4 weeks after birth and is usually attached to the infant’s face, neck, chest, etc. After birth, infants are no longer able to obtain hormones from the mother via the placenta, resulting in altered hormone levels in the body or the influence of residual hormones obtained from the mother, which may result in small bumps of white acne on the skin. Generally, no special treatment is needed, and the epidermis should not be artificially punctured to avoid infection. As long as the skin is kept clean, acne can naturally subside; 2. Cornea: Cornea is the appearance of tiny white bumps on the nose, chin and forehead of infants; it is usually present at birth and is formed when the sebaceous glands of infants are not fully developed and sebaceous glands accumulate. Corn rash usually disappears on its own a few weeks after birth and has no effect on the infant’s body; 3. Crystal corn rash: This condition, also known as white prickly rash, is mainly due to sweat overflowing under or into the stratum corneum and manifests clinically as superficial white rice grains of pinpoint size without a surrounding redness and generally without conscious symptoms. It can be absorbed within 1-2 weeks with flaking in affected children.
