1. Caused by allergies

Skin allergy is an abnormal reaction of the skin to external stimuli. When the allergen contacts the body, it prompts the body to produce corresponding antibodies, triggering an antigen-antibody reaction with varying degrees of severity. Common manifestations include redness, itching, red blood streaks, dryness and desquamation, blisters, small red bumps, tingling, burning and tightness. If the above situation occurs, you need to carefully choose daily care cosmetics and pay more attention to it in your life. This can effectively improve skin allergies.

2. Allergy medications

If it is an allergic attack, it is recommended that you take oral anti-allergic drugs. In addition, you must pay attention to staying away from allergens, and you must eliminate allergic factors or avoid contact as much as possible. This is the only way to control it fundamentally. Or you can go get an allergy test. After checking clearly, avoiding contact with allergens can fundamentally control it.

3. Eczema

If it is eczema, you should avoid spicy foods and irritating foods such as fish and crabs, and eat a light diet.
