Melanin content varies greatly, however in general darker skinned people have additional melanin than lighter skinned. (Although fairer skinned people are usually additional prone to getting sunburn than darker skinned people, this actually does not exclude the latter from risk.)
Sunburn destroys cells in the outer layer of the skin, damaging tiny blood vessels underneath. Burns deeper into the skin’s layers conjointly injury elastic fibers in the skin, which over time and with repeated sun overexposure, can result in the appearance of yellowish, wrinkled skin.

With the incidence of skin cancer rising dangerously in several components of the globe, and with its ability to develop and establish itself within the body ‘long’ before external signs are detected, — paying attention to the current facet of sun exposure and sunburn should definitely not be ignored if we tend to are serious concerning preserving our health.
Now while it might be easier to ignore the consequences of sunburn occurring at a cellular level, ignoring the external symptoms of sunburn in the times immediately following such exposure is entirely another matter.
While sunburn is typically not immediately obvious, skin discoloration (starting from slightly pink to severely red or even purplish) will initially appear from 1 – 24 hours when exposure. Although pain is usually worst 6 – 48 hours afterward, the burn will continue to develop for 24 – 72 hours when the incident. Where there is skin peeling, this typically occurs 3 – 8 days when the burn occurs.
While minor sunburns sometimes cause nothing more than warm/hot skin, slight redness, and tenderness to the affected area, — in more serious cases, extreme redness, swelling and blistering can occur. These blisters filled with fluid could itch and eventually break. This can then cause peeling of the skin, exposing a fair tenderer layer of skin underneath.
Severe sunburn will cause very red, blistered skin however will also be in the course of fever, chills, nausea (in some cases vomiting), and dehydration. In instances of utmost sunburn where the pain is debilitating, medical treatment might be required.
While the immediate effects of sunburn will certainly be painful and cause discomfort, the real deterrent to UV overexposure should be the potential injury to your long-term health – as well as the risk of premature aging of the skin together with skin cancer.
