Why Does My Face Turn Red When Exposed to the Sun?

Update Date: 2024-05-20 Source: Network

In summer, the sunlight is intense, and the ultraviolet rays in the sunlight can cause damage to the skin. If the skin is sunburned and only shows redness without pain or burning sensation, generally no special treatment is required and it will gradually recover by itself. If there is discomfort, you can use an ice towel to apply ice to the skin for improvement. However, if the skin damage is severe, it is recommended to seek medical attention. What causes the face to turn red when exposed to the sun? Let's take a look at it next.

1. What causes the face to turn red when exposed to the sun?

If the face turns red after sun exposure, it is necessary to carefully observe the appearance of the redness. If it is just a blush that quickly returns to normal, it may be due to damage to the stratum corneum of the facial skin, resulting in a decrease in skin barrier function and causing a stimulatory erythema. In this case, topical hyaluronic acid gel or human-like collagen milk can be used for repair, which can effectively increase the thickness of the stratum corneum, restore the skin barrier function, and eliminate the redness.

If there are obvious red blood vessels, peeling, and accompanying obvious itching on the face, it may be ultraviolet dermatitis, which is a specific symptom caused by the skin's sensitivity to ultraviolet rays. It is a sensitivity reaction. Special ultraviolet wavelengths act on the surface of the skin, causing the diameter of local capillaries to increase and specific inflammation of the skin to occur, resulting in a red state.

2. What to do if the skin is sunburned?

If there is only redness without pain, burning sensation, or other symptoms after sunburn, no special treatment is required, and it will gradually recover by itself. If there is discomfort, you can use an ice towel to apply ice for relief. However, if the skin damage is severe, it is best to seek medical attention.

3. Precautions for sunburn

If the skin is only slightly red after sunburn, no treatment is necessary. Just take care of it and protect it. Cold compresses can also be used. If there is pain and dehydration in the sunburned area, it is recommended to visit the burn department of the hospital. People who are prone to sunburn, i.e., those who are allergic to ultraviolet rays, should apply sunscreen and use an ultraviolet-proof umbrella when going out to prevent ultraviolet ray exposure and burns.
