Heat rash, sun rash — what’s the difference

If you have not taken the appropriate prevention measures and pimples have appeared on your skin –particularly on the neckline, neck, shoulders and legs-, you can opt for two types of treatment: natural or antihistamines.

Like desensitisation, the effects of hardening are lost in the winter, so you’ll have to build up your resistance again in the spring.

Your skin may harden (become more resistant to sunlight) during the summer, which means more sun can be tolerated without your skin reacting.

Sun allergy and pimples are closely related. In fact, the appearance of white pimples and the typical skin rash can turn out to be a clear symptom of what is colloquially called allergy pimples or polymorphic light eruption, its most common form.

Hardening of the skin does not always happen, and some people with very sensitive skin may even get the rash in the winter.

These bumps can then form raised red patches called plaques. These typically appear on the arms, legs, and chest. Plaques can also include fluid-filled blistered areas called vesicles.

Medically, sun rash is described as a type 4 delayed hypersensitivity immunological reaction. During this reaction, the T cell does not function properly, which causes a decrease in the normal immune suppression in the skin caused by ultraviolet (UV) light. This then creates an inflammatory response.

For many people with polymorphic skin eruption, the rash appears every spring and remains a problem throughout summer before settling down by autumn.

Genetics

Sun rashes can present after exposure to the sun. The rash will heal if the skin is covered and not exposed to additional sunlight.

When a sun rash occurs, there is a delayed, abnormal response to UV light exposure from antigens in the skin. This causes an inflammatory response. Sun rashes are caused by ultraviolet A (UVA) radiation in 75% to 90% of cases and can even occur when sunlight comes through a window. Ultraviolet B (UVB), the primary cause of sunburns, can also cause sun rashes.

If the skin is exposed to more sunlight before the rash has cleared up, it’ll probably get much worse and spread.
