What should I do if my skin is burned and turned red by welding?

When skin is reddened due to welding heat exposure, the following measures can be taken:

1. Immediately apply a cold compress using a wet towel or ice pack to the affected area for no more than 20 minutes at a time. This helps lower skin temperature and reduce capillary dilation, thereby alleviating redness.

2. If symptoms persist, use moist dressings with physiological saline or other medications as directed by a physician, and apply topical ointments such as mometasone furoate cream or urea cream to reduce skin inflammation and discomfort.

3. During treatment, keep the skin clean and dry, avoid prolonged exposure to ultraviolet light, and minimize or avoid using irritating skincare products to prevent worsening of symptoms.

If severe peeling, blistering, or similar conditions occur, seek medical attention promptly.
