Red bloodshot on the hypothenar eminence of the palm

It is generally recognized that our limbs help us in our daily lives, but many situations in life can cause some bad conditions to our limbs. For example, there are red bloodshot on the hypothenar line of the palm. Many people may not take it seriously, but in fact it is a reaction to the condition of our body. The most common cause of this situation is altitude and living environment. The following is a detailed description of this aspect

In daily life, we often see some people's facial skin turn red, and we can see the dilated capillaries with the naked eye. Some of them appear as red or purple spots, dots, lines or star-shaped lesions. This is telangiectasia, commonly known as blood-red threads. It is a skin lesion that occurs on the face or trunk. Most of them are acquired, but some patients are congenital. Facial capillary dilation is the main cause of beauty problems. It is more common in women, and the clinical manifestations are filamentous, punctate, star-shaped or flaky erythema on the face. If you look closely, you can see many red blood vessels on the skin, like strands of red threads.

Causes

Physical factors

For example, the stimulation of temperature changes causes the tolerance of capillaries to exceed the normal range, causing the capillaries to dilate and rupture. Excessive sun exposure can also cause chronic photodermatitis, dry skin, etc.

Environmental factors

Long-term living in a relatively harsh living environment, such as the thin air in the plateau and skin hypoxia, leads to an increase in the number of red blood cells and compensatory vascular dilation. Over time, the vascular contraction function is impaired, causing permanent capillary dilation. Sailors, cooks, farmers and athletes who are exposed to wind, cold and heat for a long time may also develop capillary dilation.

Hormonal dilation

It is a sequelae of inappropriate treatment, such as the abuse of topical medications on the face.

cosmetic

Cosmetics or long-term "monthly skin care" and improper skin replacement can cause sequelae.

The acidic ingredients in skin peel products seriously damage the protective function of the skin's stratum corneum and the elasticity of capillaries, causing the capillaries to dilate or rupture.

complication

It mainly refers to people suffering from certain skin diseases (such as rosacea, etc.), and there are also some people whose causes are unclear. With this skin disease, the face becomes red very easily, and when you have a fever, are emotionally excited, do strenuous exercise or drink alcohol, not only will the color deepen, but the entire face will also become flushed (i.e. red face, Guan Gong face), which is difficult to subside and greatly affects the appearance.

Home Care

Apply biochemical technology energy skin care products externally to thicken the skin's stratum corneum, activate basal cells, and increase the cells' ability to release various proteins. Return the protruding diseased blood vessels to their original physiological position. Repairs damaged elastic fibers in capillaries.

Treatment

Cosmeceutical treatments

Experts suggest: To solve the problem of capillary dilation, it is recommended to use methods such as promoting blood circulation and removing blood stasis, clearing blood scale from capillaries, restoring blood vessel elasticity, removing old biochemical new skin, repairing the stratum corneum and whitening the skin, so as to achieve the purpose of curing capillary dilation.

Laser therapy

Previous treatments and their shortcomings

Telangiectasia has long been a difficult problem to treat in dermatology. Before the invention of new lasers, the commonly used methods include: cryotherapy, high-frequency electrosurgery, isotope radiotherapy, etc. Although some of these methods can achieve certain therapeutic effects, they are prone to cause serious complications such as ulcers, scars, and radiation necrosis, and cannot achieve the ideal cosmetic effect, which is unacceptable to people who love beauty.

1. High-tech laser treatment of telangiectasia

There has been a leap forward in the treatment of telangiectasia, which is the use of a 585nm wavelength laser therapy device. The principle of laser treatment of vascular skin damage is mainly to use the selective absorption of a certain wavelength of laser by oxygenated hemoglobin, thereby leading to highly selective destruction of vascular tissue. In addition, intense pulsed photon rejuvenation can also significantly improve telangiectasia, and practice has proven that it is a safe and simple treatment method. The skin remains intact after treatment, which is good news for the majority of patients.

2. New laser or strong light treatment

Possible problems and solutions

(Because the skin lesions are superficial, the treatment is simple and quick, and generally there are no complications after surgery. A few patients may have the following complications):

1. Soft tissue edema: often occurs on the eyelids and face, and generally disappears within a few days.

2. Pigmentation: A small number of patients have mild pigmentation reactions after laser treatment. Generally, no treatment is required. If necessary, 0.025% to 0.05% retinoic acid ointment, hydroquinone cream, etc. can be used to accelerate the fading of pigmentation.

3. Recurrence of the disease: Recurrence of the disease due to recanalization of blood vessels within 2 to 4 weeks after treatment. Those who have recurrence can be treated a second time, and the second irradiation range should be slightly wider and deeper than the first.

With this skin condition, conventional treatments are usually ineffective and medications have little effect. Since the lesions are usually located deep within the skin, they are difficult to remove with conventional treatments (such as freezing and electrolysis). If the treatment is too shallow, the lesions cannot be removed. If the ideal treatment depth is to be achieved, scars will inevitably be left. Due to lack of medical knowledge, some beauty salons in society use monthly facial mask treatments in the hope of eliminating the dilation of capillaries. This is impossible, on the contrary it will get heavier and heavier.

Disease causes

A facial phenomenon caused by dilation of facial capillaries or the superficial location of some capillaries. The skin is thin and sensitive, and the face becomes redder when it is too cold, too hot, or emotionally excited. The causes of red blood streaks can be roughly divided into two types: genetic and induced. Genetic type[3] is often inherited in families. The most common type is the induced type, and the main causes are as follows:

1. Long-term local use of corticosteroids can cause capillary dilation, leading to thinning and atrophy of the skin;

2. Blood circulation is blocked and blood vessel walls become stagnant, causing red blood streaks on the face;

3. Misuse of skin care products containing hormones or drug ingredients, photorejuvenation, acid peels and other exfoliating treatments can cause the skin's stratum corneum to become thinner and more transparent, making it easy for red blood streaks to form.

4. The skin itself is sensitive and is sensitive to external stimuli, which causes the peripheral blood vessels to tighten and loosen from time to time, presenting a state of repeated congestion, causing the blood vessels to dilate tortuously and form red blood streaks.

Drug action analysis

Active ingredients and mechanisms of action of drugs for treating telangiectasia

The mechanisms of action of drugs used to treat telangiectasia are as follows:

1. Increase the skin's barrier function: promote metabolism, repair and adjust the normal thickness of the skin, restore epidermal function, improve the skin's ability to resist various external stimuli, and improve the skin's sensitive state. Commonly used active ingredients include chamomile, arnica, ivy, cactus, etc.

2. Repair capillaries: mainly achieved through the following three methods:

1. Protect the integrity of capillaries: avoid external stimuli that damage skin capillaries, avoid increasing blood flow in skin capillaries, thereby protecting capillaries from damage and ensuring the integrity of the capillary endothelial basement membrane.

2. Repair damaged capillaries: This is mainly achieved through three ways: resisting factors that hinder the repair of broken capillaries, improving the contraction and expansion function of capillaries, and improving the microcirculation of facial capillaries.

3. Relieve capillary irritation: This helps to relieve symptoms and reduce the extent of capillary dilation. By reducing inflammation, it reduces blood flow to the capillaries, thereby reducing the extent of redness. Ingredients that are effective in repairing red blood streaks include witch hazel, horse chestnut, butcher's eye tree, chamomile, etc.

3. Enhance the activity of collagen and elastin: Enhancing the activity of collagen and elastin can enhance the support of the skin, prevent and treat superficial capillaries, and thus prevent the phenomenon of red blood streaks on the face. Among the plant raw materials that repair red blood vessels, the grape polyphenols (flavonoids, tannins, catechins, and proanthocyanidins) contained in grape seeds not only enhance the elasticity of blood vessels and promote blood circulation, but also enhance the vitality of skin collagen and elastin.

4. Functional plants and their active ingredients for preventing and treating red blood streaks

It can be roughly divided into three categories: flavonoids, saponins, and tannic acid:

(1) Plant flavonoids: Plant flavonoids can increase the activity of free radical scavenging enzymes and inhibit lipid peroxidation reactions, thereby relaxing vascular smooth muscle, protecting vascular endothelial cell function and inhibiting the proliferation of vascular smooth muscle cells (VSMC). This category includes Astragalus and Citrus aurantium

(2) Saponins: They have the functions of anti-inflammatory exudation, increasing venous tension, improving microcirculation, and maintaining the normal structure of venous blood vessel walls. Commonly used are horse chestnut and false leaf tree

(3) Tannic acid: It is an effective hemostatic agent that can strengthen blood vessels and has anti-inflammatory functions. It also has antibacterial, analgesic, anti-inflammatory, antioxidant and comprehensive protective effects that can reduce free radical damage caused by ultraviolet radiation. Commonly used ones include witch hazel, etc.
