It often occurs in the middle of the face, the tip of the nose and the alar part, and can also extend to the cheeks, jaw and forehead. Mild patients only have telangiectasia, local skin flushing and more oil. Then red papules and pustules may appear. In severe cases, the tip of the nose increases and the hair follicles open, leading to rhinoplasty. The cause of this disease is not completely clear. It may be caused by many factors on the basis of seborrhea.

At present, most scholars believe that hair follicle infection is an important factor, but it is not the only factor. Alcoholism, spicy food, high temperature and cold stimulation, digestive and endocrine disorders can also promote the onset. In terms of prevention, first of all, we should pay attention not to eat spicy food that is too irritating, especially to avoid alcohol, cold and hot stimulation, and not to be emotional and nervous. Especially when it is mild, it can be treated orally or externally. Generally speaking, vitamin B groups, such as vitamins B2, B6 and vitamin B complex, are taken orally. Oral tetracycline or metronidazole or minocycline. External use of 5% sulfur cream or sulfur lotion or chlorine tincture.

Traditional Chinese medicine can be decocted with Liang Xue Siwu decoction or Taohong Siwu decoction combined with loquat Qingfei decoction. If the tip of the nose is hypertrophy, it can be frozen or ground in liquid nitrogen, and you should go to the hospital for treatment.

Why do you get rosacea? At present, the cause of this chronic external nasal skin injury is not very clear. It is generally believed to be related to a kind of hair follicle keratosis parasitic in sebaceous glands of hair follicles. In addition, gastrointestinal dysfunction, endocrine disorders (such as irregular menstruation, menopause, emotional instability, etc. ) and chronic infection in the body may be the pathogenic factors of rosacea People who often drink, smoke and love spicy food have a higher prevalence rate. The root cause of rosacea's redness on the face and nose is the long-term expansion of local capillaries, which leads to skin congestion.

Erythema of rosacea is often located at the tip of nose, cheeks, chin and brow, and the boundary between erythema and surrounding skin is unclear. With the development of the disease, the nose is red and swollen for a long time, the capillaries are dilated, and there may be small papules and small thick blister sores on the tip of the nose; In severe cases, small nodular protrusions of different sizes can be seen on the tip of the nose, which looks like vegetation, so it is also called "nasal wart".

Rosacea has little effect on general health except beauty. It's just that the nose often feels local fever. If complicated with infection, it may be accompanied by pain, and other symptoms are not obvious.

At present, there are many treatments for rosacea, and it is difficult to cure it completely because the cause is not clear. There are treatment measures for keratosis folliculi, as well as comprehensive treatment of anti-infection and hormones. Generally speaking, we can control the development of the disease and relieve the symptoms by looking for the inducing factors that cause the disease, such as quitting smoking and drinking. Eat less spicy food such as pepper, onion and garlic; Eat more fruits and vegetables to keep the stool unobstructed; Proper use of vitamin B6, B 12 and topical rosacea ointment can achieve certain therapeutic effects. For rosacea that has not healed for a long time or has formed rhinoplasty, rosacea cutting and plastic surgery can be considered, just to restore the normal nose shape.

Clinical manifestations of rosacea

Rosacea is divided into three stages, with no obvious boundary in each stage, which develops slowly and is often complicated with acne and seborrheic dermatitis.

Primary erythema telangiectasia. At first, the nose was red and the surface was greasy and shiny, and gradually spread to cheeks, eyebrows and chin. Erythema first appeared, followed by persistent congestion erythema and telangiectasia. The two sides of the nose, the tip of the nose and the cheeks are dendritic, with enlarged hair follicles and large pores, which are blocked by sebum and sebum overflows. Local fever and congestion are often aggravated by eating spicy food, climate change, emotional tension, anger, fatigue and menstrual period.

Secondary papular stage. Paroxysmal inflammation on the face, papules, pustules, red sesame to soybean-sized nodules, gradually aggravated.

Tertiary hypertrophy, also known as rhinoplasty. The tip of nose and alar are dark red or purplish red, and the skin begins to be rough and thickened, gradually becoming hypertrophy, forming deformed rhinoplasty. At this time, the hair follicle mouth expands to form pores, the capillaries obviously expand to form red blood silk, and sebum secretion is vigorous. Severe eyebrows, chin and cheeks also have similar skin lesions.

Rosacea is a chronic disease that damages people's appearance. There are diffuse flushing and telangiectasia in some areas, accompanied by papules, pustules and keloids. There are more men in adolescence and more middle-aged women. A few pathologies can be complicated with conjunctivitis, blepharitis and corneal angiogenesis, which is called eye wine residue.

Why rosacea hyperplasia hypertrophy;

Erythema is mainly intradermal vasodilation, with a small amount of non-specific inflammatory cells infiltrating around blood vessels and sebum, and some demodex can be found. In the pustular stage of papules, the infiltration of inflammatory cells in dermis is aggravated and diffuse. A large number of connective tissue hyperplasia, vascular proliferation and expansion, diffuse inflammatory infiltration, increased number of sebaceous glands, enlarged glands, dilated sebaceous ducts and filled with protein substance can be seen in pustules.

In the past, there was no special and effective treatment for this disease, and laser treatment is also used at present. The key to treatment is to improve the symptoms without affecting the cosmetic function of the external nose. Different treatment methods, such as intermittent irradiation and vaporization during laser treatment. Nd: YAG and CO2 laser are mainly used for treatment. The former can act on tissues below epidermis, while the latter has strong effect on epidermis and poor effect on subcutaneous tissue. However, the effect of laser treatment is still not ideal, and it is easy to relapse. So far, there is no complete cure for rosacea in the world.
