What to do if your face suddenly becomes red and itchy

In fact, the symptoms of sudden redness and itching on the face mostly occur in female friends, mainly due to facial allergies caused by the cosmetics they use. But there are also a small number of patients who are caused by their own reasons. For example, patients with capillary dilation are prone to such symptoms. This must be taken seriously.

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.
