Sunburned skin appears red and itchy. Depending on the severity, skin edema, extreme sensitivity to touch and / or burning can also be associated. In more serious cases, symptoms such as blistering and superficial peeling follow. If a large area of the body surface is affected, general symptoms (caused by the release of inflammatory cytokines) can also develop, including fever, chills, and general weakness.
Sunburns require prompt intervention and a lot of caution, as, over time, they can prove to be dangerous to health.

Sunburn is a milder version of sunburn, but no less serious. It is, in fact, a form of skin inflammation, characterized by redness and itching. This skin reaction is also caused by incorrect sun exposure, without adequate protection.
Sunburn is a lesion limited to the most superficial skin layers that precedes a real "first degree burn."

- They increase the blood flow in the photo-exposed areas;
- They promote the release of cytokines and inflammatory mediators, such as histamine (responsible, among other things, for the itching sensation).
The combined effect of these factors determine peripheral vasodilation and increased permeability of the capillaries which lead to redness, edema, heat and other uncomfortable sensations typical of skin inflammation.
