It will turn red and itchy after scratching. So what is the disease?

Erythema on the legs may be caused by allergies such as urticaria, erythema nodosum, erythema multiforme, erythema annulare, polyarteritis nodosa, etc. Different diseases can manifest as erythema depending on the different manifestations.

Here's a simple way to deep clean your skin at home :

1. Cleaning: Use a weak acid facial cleanser to clean the skin.

2. Steam your face : Pour boiling water into a basin, place your face close to the steam, and then cover your face with a towel for about 10 to 15 minutes. This will open up your pores, which is especially useful for oily skin.

3. Exfoliation : Apply an appropriate amount of exfoliating products (including scrubs, exfoliating creams, etc.). This can cleanse the skin, relax muscles, and effectively stimulate and improve lymph and blood circulation.

4. Moisturizing: It is very important to use a mask that suits your skin type. In addition to further cleansing, it can also deeply moisturize the skin, replenish moisture, and prevent allergies caused by dehydration.

A new definition of allergy

Simply put, it means being allergic to a certain substance. When you eat, touch or inhale a substance, your body will have an overreaction; the substance that causes this reaction is called an "allergen." Under normal circumstances, the body produces antibodies to protect the body from disease; but the body of an allergic person will mistake normal, harmless substances for harmful ones and produce antibodies, and this substance becomes an "allergen." This allergic reaction can cause some physical problems that do not usually occur in normal people.

Fight against UV rays

Excessive ultraviolet rays may cause skin burns at any time, resulting in terrible allergic symptoms such as erythema, darkening, and peeling. Therefore, after applying basic skin care products, be sure to apply sunscreen. However, the ingredients of some sunscreens are also one of the factors of allergies. You should choose some physical sunscreens with simple ingredients, and try to avoid applying them directly on the skin surface, which will cause relatively less irritation to the skin.
