The skin is red and swollen after applying the band-aid

Some people will still feel their skin becoming red and swollen after putting on a Band-Aid, which can be very scary. In fact, some people are not suitable for putting on Band-Aids at all. Once they do, their skin will become allergic. Moreover, when their skin is exposed to some strong cold stimulation, it will also become red and swollen.

Regional factors: such as plateau climate stimulation and high altitude, which causes skin hypoxia, leading to an increase in the number of red blood cells and causing capillary dilation and rupture.

Physical factors causing skin redness: cold stimulation, dry air, sandy climate, and sun exposure can cause capillary tolerance to exceed the normal range, leading to capillary dilation and rupture.

Occupational factors: such as chef. Welders and other flames are burning.

Beauty care factors: such as the damage caused by the acid components in skin care products and the dilation and rupture of hormone-dependent capillaries, as well as the fragility of skin immunity caused by skin resurfacing. Frequent visits to beauty salons for facial care can also lead to dilation and rupture of blood vessels.

Complications of local or systemic diseases cause telangiectasia and rupture.

Personal habit factors of skin redness: such as liking spicy food, being addicted to smoking and drinking, are also closely related to the onset of telangiectasia.

Ultraviolet radiation: Strong ultraviolet radiation damages the stratum corneum, causing poor capillary dilation and causing red blood streaks;

The stratum corneum has been damaged due to stratum corneum polishing, photorejuvenation, etc., causing red blood streaks;

Using some cosmetics containing heavy metals and other toxins will remain on the epidermis, causing allergic reactions, damaging the stratum corneum, and causing red blood streaks;

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

Living in high-altitude cold areas or suffering from frostbite, which results in obstructed blood circulation and stasis of blood vessel walls, causing red blood streaks on the face and redness of the skin;

After cosmetic skin resurfacing, because skin resurfacing products mainly contain "benzoic acid", "benzoic acid" repeatedly stimulates the thin and delicate facial area, exposing the unprotected dermis to the outside and receiving strong ultraviolet radiation;

Sensitive skin usually has a thin stratum corneum. It is more sensitive to external sunlight, drugs, cosmetics, temperature (hot or cold), etc., which causes the blood vessels to tighten and loosen, showing repeated congestion, causing the blood vessels to dilate and form red blood streaks.

The facial phenomenon is a criss-cross pattern of lines, like a spider web, distributed dispersedly. In severe cases, the lines may connect into flakes. This type of skin is thin and sensitive, and the face becomes redder when it is too cold, too hot, emotionally excited, or when the temperature changes suddenly. In severe cases, deposited pigmentation may also form.
