Red blood is a common problem for people with sensitive, hormone-dependent dermatitis, and its care is very troublesome, making the patient physically and mentally exhausted, so what should I do with you, red blood? Causes of redness As you know, the upper layer of our skin is the epidermis, which mainly plays a protective role (barrier), and the lower layer is the dermis, which provides nutrients and carries out related physiological activities. In the dermis, there are a large number of small blood vessels and capillaries, transporting nutrients, taking away waste. The walls of the capillaries are so thin that the thinnest vessel allows only one red blood cell to pass through, which can be considered as thin as a cicada’s wing. Many physiologic and pathologic factors can cause capillaries and small blood vessels to dilate. Women’s epidermis itself is very thin, so the blood vessels expand, the walls become thinner, blood flow increases, so the naked eye can see more red color, which is the basic cause of red blood. The main causes of vasodilatation 1, nervous and psychological factors: nervousness, excitement, agitation, anger; 2, physical factors: heat, cold, sun exposure, friction (mechanical force); 3, chemical factors: acid, alkali, salt; 4, pathological factors: bacterial infections, skin injuries, etc., leading to inflammation; 5, the wrong skincare: over-skincare, over-exfoliation, excessive to the salon to do the care, resulting in thinning of the epidermis, the skin is damaged, the barrier function is fragile. Damaged and fragile barrier function. The typing and treatment of redness 1. Dangerous edge type Description: Strictly speaking, this is not redness, it is a prelude to redness, and understanding it will help prevent it. This type of skin has no major problems, white and red, and is often praised for its good skin. On closer inspection, faint redness can be seen. In case of friction and irritation, a visible red mass will appear, but it will recover relatively quickly after the irritant disappears. This is the type that is on the edge of danger. Reason: the epidermis is too thin, exfoliation diligently, but not yet damaged to unbearable, often this is the case, but also some people are born. Care methods: avoid stimulation, do not exfoliate, less friction, avoid the use of irritating skin care products, generally can recover on their own. 2, flushing type Description: Skin in the slightest stimulation, even in the case of no stimulation is also very easy to appear a large area of flushing. Can’t see the obvious filamentous blood vessels, just red. After the stimulus is eliminated, the redness takes a while to recede. Under successive stimuli, the flushing persists or worsens and does not disappear, but there are no other problems with the skin. Causes: The skin is already slightly inflamed or moderately damaged, and the epidermis is already very thin. The usual lack of sun protection, excessive skincare, and over-exfoliation to a certain extent is this type, which may be accompanied by a rash, but be aware that this is not acne. This can also happen with improper post-procedure care such as laser treatment and fruit acid peels. Nursing method: first review their own skin care behavior is appropriate, whether there is a variety of aforementioned stimulation and damage factors, Babu agent masks, etc. can be used as care products. 3, persistent inflammation type Description: Skin not only persistent redness, rash, but also accompanied by flaking, seborrhea, and even infections, the use of some cosmetics will be stinging, this type of inflammation secondary to the root cause of inflammation, rather than redness or barrier itself. Reason: For those who take care of their skin excessively, it is mostly due to the fact that after the skin has been stimulated and damaged too much, the skin loses enough defense, leading to bacterial infections, fungal infections, and so on, and some pustules will also appear. Another type of normal skin due to some factors of infection, inflammation, because the inflammation leads to redness of the skin. The common ones are seborrheic dermatitis, hormone-dependent dermatitis mixed with fungal infection inflammation. Rosacea and perioral dermatitis can also cause redness of the skin. The inflammatory type cannot be considered redness, but it can cause redness to develop. Nursing method: first review whether there has been excessive skin care and irritating factors, first remove such factors, and then depending on the severity of the decision to seek medical treatment or use some commonly used medications for self-treatment in order to control the inflammation, when the situation improves, the use of restorative products. 4, spider web type Description: the most serious type, skin tight, shiny, thin, naked eye can see thick bright red, dense as a spider web of red blood. This kind of red blood line expansion is permanent – no stimulating factors are also clearly visible, there are stimulating factors is even more powerful. Cause: Substantial enlargement of blood vessels. Usually a consequence of hormone-dependent dermatitis, sunburn, rosacea, etc. Treatment: Difficult to treat with skincare products, but fortunately there are now lasers or intense pulsed light that can be used more perfectly. By means of a photothermal effect, these blood vessels are closed and blood can no longer pass through.
