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

Reddening of the face upon exposure to the sun may be caused by irritant erythema or ultraviolet dermatitis, and it is recommended to actively seek medical attention.

If the face turns red after exposure to the sun, 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 an irritant erythema. In such cases, topical hyaluronic acid gel or human-like collagen protein cream can be used for repair, which can effectively increase the thickness of the stratum corneum, restore skin barrier function, and eliminate the redness.

If there are obvious red blood vessels and peeling on the face, accompanied by significant itching, it may be ultraviolet dermatitis. This condition is a specific symptom caused by skin sensitivity to ultraviolet rays, a sensitivity reaction. Special ultraviolet wavelengths act on the skin surface, causing local capillaries to dilate and the skin to develop specific inflammation, resulting in redness.

After sunburn, it is recommended to actively seek medical attention. For patients with severe local sunburn symptoms, cold spray treatment is recommended to relieve symptoms such as local redness, swelling, and burning sensation. Facial care should use products with more moisturizing ingredients to promote the repair of the skin mucosal barrier as soon as possible. If severe itching is accompanied, it is recommended that patients take oral antihistamines. During the treatment period, attention should be paid to sun protection when going out, avoiding going out between 10-16 o'clock, and wearing a sun hat and umbrella when going out.
