How to improve acne skin? First of all, you have to treat the symptoms

Skin care: acne skin care

The development of acne-prone skin

1. The sebaceous glands overproduce sebum under the stimulation of androgens. There are two key words here: androgen and increased oil secretion.

2. Excessive keratinization and abnormality of the hair follicle opening lead to blockage. This is a common cause of adult acne. Sometimes dry skin can also cause acne. The main reason is that the skin's metabolism is disrupted, leading to the accumulation of aging cuticles. Once the cuticle becomes thicker, the opening of the sebaceous glands becomes narrow and sebum cannot be discharged smoothly. At this time, if there is also a disorder in hormone secretion and increased sebum secretion, it is very easy to cause blockage, which in turn leads to acne.

3. Excessive reproduction of Propionibacterium acnes. Propionibacterium acnes is an anaerobic bacterium, and the blockage of the hair follicle opening creates a good growth environment for it.

4. Release of inflammation and pro-inflammatory mediators. The metabolites of Propionibacterium acnes can induce or aggravate inflammation, which manifests itself as papules, pustules or nodules. After the inflammation subsides, there will be pigmentation-acne marks.

Whiteheads are closed comedones, which are difficult to cure clinically.

Cause of formation: The opening of the sebaceous gland of the hair follicle is blocked by keratinocytes, and keratinized substances and sebum are filled inside, which is different from the outside world, forming closed root thorns, which look like slightly protruding whiteheads. The formation of closed comedones is due to a series of symptoms caused by endocrine disorders in the body, and the direct cause is that the stratum corneum is too thick. Closed comedones are unstable acne that can easily develop into pimples.

The symptoms of closed comedones are because the pores are closed and the oil inside is not oxidized, and a white top can be seen. Closed comedones are generally caused by overnutrition, a single food or a diet of health products. They are more common in oily or combination skin. When squeezing whiteheads, a white thread-like object is squeezed out; its shape is a small raised white grain.

Blackheads are also called blackheads, which are open comedones.

Cause of formation: The surface layer of sebum that clogs the pores is directly exposed to the outside and comes into contact with the air and dust in the air. The opening of blackheads is connected to the outside world, forming open comedones, which appear as black spots of varying sizes on the surface.

Blackheads are characterized by black spots in visibly enlarged pores, which look like worms when squeezed out and have black tips. Blackheads are the later development form of closed comedones without heads, but many whiteheads are very "conservative" and will never "open" throughout their lives. Blackheads will not form. Blackheads are mainly composed of a "plug"-like substance composed of sebum, cell debris and bacteria, which blocks the opening of the hair follicles. Combined with dust, dirt and oxidation in the air, the end that comes into contact with the air gradually turns black, hence the inelegant name - blackhead.
