baby blackheads
Introduction
Introduction Infantile acne, also known as Acne neonatorum, is caused by hormones brought by the newborn's placenta. It is usually found in the second half to three months after birth. Mostly on the forehead and face, the shape has whiteheads, blackheads, and pimples. The cause of the disease is unclear, and may be caused by increased androgen secretion at birth. There are family tendencies that occur within 3 months, almost all of them are male. Acne can resolve within a few months. The scar can be left behind.
Cause
Cause
The cause of infant blackheads:
(1) Causes of the disease: The cause of the disease is unclear, and there is often a family history. The same patient in the family may be related to heredity and is prone to severe acne during puberty.
(B) the pathogenesis: at birth, androgen secretion increased, sebaceous glands developed well, stimulating hair follicles. Individual children may be associated with precocious puberty or masculinization syndrome, which may be related to endocrine function.
Most of the acne occurs from half a month to three months after birth, medically known as baby acne. At present, the medical community believes that acne is caused by many factors such as androgen, normal flora in hair follicles, and genetic factors. If the baby gets too much androgen from the mother before birth, it will promote the secretion of sebaceous glands after birth, and the baby's face is a developed part of the sebaceous glands. Excessive sebum will accumulate in the hair follicle, causing the skin. There are a few small pimples in the uplift, usually in the cheeks and the number of ministers are dozens or dozens. Due to the obstruction of sebum discharge, it is mixed with the cells and microorganisms that have fallen off the hair follicle wall, and accumulates in the hair follicle mouth and becomes a yellow-white small spot. When it is oxidized by air, it becomes black and becomes a blackhead acne. Propionibacterium acnes in the hair follicles multiply by chance and cause inflammation. If the inflammation is heavier, hard nodules of varying sizes are formed around the hair follicles, the skin is reddish, and there are symptoms such as itching. If you ignore the treatment, or squeeze the child's facial rash by hand, it is easy to secondary bacterial infection, causing suppuration, making the condition worse, forming nodules, cysts, and even scars.

Symptoms of infant blackhead acne:
Whitehead acne: Acne is divided into whitehead acne and blackhead acne, whitehead acne we call it closed acne, closed acne is more difficult to cure in clinical cure. Whitehead acne occurs because the stratum corneum is too thick, and whitehead acne is an unstable acne (closed type) that easily evolves into a blister.
