redness of the skin
Introduction
Introduction Redness of the skin is a facial phenomenon caused by poor facial telangiectasia, damaged stratum corneum or a superficial capillary location. It is criss-crossed, like a spider web, with a dispersive distribution. In severe cases, it will become flaky and change. Into the red face, this skin is thin and sensitive, too cold, overheated, emotional, and the face is redder when the temperature suddenly changes. The facial redness of the patient's face looks redr than normal, and some are only red on both sides of the crotch, and the border is round. This skin is thin and sensitive, and it looks redder when it is too cold, too hot, or emotional. In severe cases, it will form sedimentary stains, which are difficult to cure. It not only affects the beauty of the appearance, but also creates a shadow on the mind, which brings great inconvenience to normal life.
Cause
Cause
Long-term wind blows, damages the stratum corneum, causing red blood. The temperature difference between cold and heat is too large, causing excessive expansion of capillaries; improper use of cosmetics, damage to the stratum corneum; thinning of capillaries due to lack of oxygen, vascular necrosis; genetic factors, epidermal thinning; long-term nutrition of the skin, allergic dehydration.
Regional factors: such as plateau climate stimulation, and high altitude, skin hypoxia, leading to an increase in the number of red blood cells, causing telangiectasia and rupture.
Skin redness physical factors: cold stimulation, air dryness, wind and sand climate, sun exposure, so that capillary tolerance exceeds the normal range, causing telangiectasia and rupture.
Occupational factors: such as a chef. Electric welders and other flames.
Beauty care factors: such as the destruction of acid components in skin care products and hormone-dependent telangiectasia rupture, and skin weakness caused by skin rejuvenation, often on the beauty salon to do suction care can also lead to vascular expansion and rupture. Complications of local or systemic disease cause telangiectasia and rupture.
Personal habits of skin redness: such as eating spicy, hobby, alcohol and so on are also closely related to the onset of telangiectasia.
Ultraviolet radiation: Intense ultraviolet radiation destroys the stratum corneum, causing poor telangiectasia and causing redness.
Long-term nutrition of the skin, allergic dehydration.

Diagnosis
Differential diagnosis
Diagnosis is generally not difficult. Sometimes, because the medical history is unclear or the physical signs are not typical, it will bring certain difficulties to the diagnosis. The main point of differential diagnosis is to grasp the characteristics of each disease, and combine the obtained medical history with the test results for careful analysis. Identification.
