There are small red spots on my arms that look like blood spots

Capillaries are distributed in every part of our body. If you find some small red spots on your arms, similar to snow spots, this is mainly due to the rupture of capillaries in the lower layer of the arms. If you stay in a relatively dry environment for a long time and your skin loses too much water, this will cause this situation. You must apply ointment in time to solve it, otherwise skin plaques will grow and it will be difficult to treat. In daily life, try not to do heavy work and pay attention to maintenance.

If you look closely, you can see many red blood vessels on the skin, like strands of red threads. Many ladies who love beauty are often troubled by their flushed faces, but many people may not know that red blood streaks will not only affect your beauty, but also your health, seriously affecting the skin's absorption of nutrients. Over time, it will lead to insufficient nutrient supply to the skin, causing symptoms of roughness, dryness and premature aging. In traditional Chinese medicine theory, it is called "red face", and the cause is attributed to heat in the heart meridian and poor blood circulation.

Blood vessels are distributed throughout the body's organs and are divided into arteries, veins and capillaries. Tiny arteries, veins and capillaries are distributed in the skin and mucous membranes. Capillary dilation refers to the filamentous, star-shaped or spider-web-like changes of these blood vessels on the surface of the skin or mucous membranes. It is bright red and does not fade after being pressed by a glass piece. It may be single or multiple and develop slowly or do not increase significantly after occurrence. It may be limited to a certain part or may be over a wide range. It may be a local change or a special manifestation of certain diseases. Most of them cannot disappear on their own, are benign, and affect beauty. Telangiectasia can be primary, such as vascular nevus, hereditary benign telangiectasia, etc. It can also be secondary to diseases such as scleroderma and rosacea.

Congenital malformation of capillaries means that the capillary walls are congenitally weak and cannot contract. This disease usually occurs on the face, neck, back of the head, and scalp at birth or shortly after birth. It can be unilateral and scattered, or bilateral and multiple. Initially, there is a lesion of varying sizes, light red, dark red, or purple-red on the skin or mucous membrane, ranging from the size of a needle tip to a limb or half of the trunk. After crying, the color deepens, the boundaries are clear, the shapes vary, and it does not protrude above the skin, but is higher in some areas. After pressure, it fades partially or completely, and the surface becomes smooth. As age increases, children or young adults may have symptoms or nodular lesions on them, mostly occurring in the lower legs and feet, which may manifest as painful purple-blue nodules and plaques, which may also ulcerate.
