Why does the skin become itchy and red and swollen? What should I do if my skin becomes itchy and red?

Skin allergies and itching, the most embarrassing thing is the redness, swelling and allergy of the facial skin. There are red bumps and you cannot scratch them when they itch, as the infection can easily spread. So how do you treat dry skin allergies?

1. All cosmetics should be stopped. Alkaline skin care products should not be used during the period of skin allergy and redness. Toners containing alcohol and fragrances should also be stopped. Because skin care products contain alcohol, after the alcohol evaporates, the skin will become drier and increase skin sensitivity.

2. If it is the first time or if sensitivity occurs occasionally, wash your face with clean water before use. If redness persists, desensitization treatment is required. You can also soak cotton or gauze with injectable saline and apply it to sensitive areas of the face. This injectable saline is highly safe and has good penetration. It has the function of reducing swelling, reducing redness and stabilizing the skin. Generally speaking, the redness and swelling will disappear after a few days. Or use ice cubes on sensitive areas of your face to help soothe them.

3. Strengthening the skin's resistance is also an effective basic measure, such as getting enough sleep, eating a balanced diet, maintaining a harmonious mood, staying away from polluted environments and allergens, and reducing skin irritation. Mild allergies will recover quickly if treated properly, but severe allergies require prompt medical attention.

4. Do not take medicine without authorization. Do not buy adrenocortical hormone ointment from a pharmacy without a diagnosis from a dermatologist, as this will harm your skin. Although it is effective in suppressing inflammation, long-term use will produce side effects and endanger health.
