Are you looking for information on solar dermatitis?
In this guide we will explain in detail what sun dermatitis is, what causes it, and how to prevent its occurrence.
When we talk about dermatitis or solar erythema we refer to an inflammation of the skin caused by overreaction of the immune system to sunlight.
Unlike simple sunburn, dermatitis manifests as a kind of sun allergy, which can articulate itself in several forms.
Let’s now see everything you need to know to protect yourself from erythema and photosensitivity and how you can prevent these phenomena.
Treatment, symptoms and tips to protect yourself from sunburn
From treatment to forms of sun urticaria, let’s look together at a range of useful information to prevent all sun-related ailments.
What is solar dermatitis
As we have mentioned, sun dermatitis is defined as a severe irritation of the skin caused by a reaction of the immune system to sunlight.
The areas most frequently affected by this disorder are the neck, back of the hands, outer part of the arms, and lower legs.
The causes contributing to the manifestation of sunburn can be many, but linked by one common thread: an inadequate reaction of the immune system to certain substances in the skin when exposed to sunlight.
The reason for this reaction by the immune system has not yet been defined, but there are some factors that certainly contribute to the activation of the phenomenon, such as:
Genetic predisposition;
Taking certain types of medications, such as certain types of antibiotics and contraceptives, which make one more prone to photosensitivity;
Chemicals contained in sunscreens or cosmetics.
We should point out that the disease is by no means contagious and can affect people of all ethnicities.
Symptoms and forms of sun allergy
Before discussing the symptoms of sun dermatitis, let us point out that there are several forms in which the disease can occur:
Polymorphous solar dermatitis: most common form, usually appearing in the spring or summer season;
Photoallergic dermatitis: skin irritation arising from a reaction triggered by the sun on chemicals in the skin or body;
Dermatitis prurigo actinica: hereditary form of dermatitis that usually appears in American Indians
Solar urticaria: a rare and acute form of dermatitis that sees the appearance of large blisters.
Speaking of symptoms, we will focus on polymorphic solar dermatitis, which is the most common form of those illustrated.
Being polymorphous, sun dermatitis can manifest with different symptoms, including:
Red dots 2-5 mm in diameter
blisters
target injuries.
These symptoms may be accompanied by a state of general malaise, characterized by itching, burning, and headache.
The reactions usually appear shortly after sun exposure and tend to decrease in intensity as the affected individual increases exposure times, because there is a progressive desensitization to the sun.
For prurigo-actinic dermatitis, the symptoms are almost the same, but they appear in different areas, manifesting as red dots on the face, for example.
Care and prevention
Inflammation of the skin and allergic reactions to the sun can be prevented by implementing a few steps:
Gradually expose yourself to the sun: avoid “sunbathing” and do not expose yourself during the hottest hours of the day (11am-4pm);
Protect yourself effectively: use a good sunscreen that can effectively protect you from ultraviolet rays. Choose a quality, chemical-free product. Also remember to apply a balm to your lips;
Use cotton or linen garments and avoid synthetic fabrics.
As for the treatment of sun dermatitis, it depends first of all on the form in which it occurs.
In any case, to make a correct diagnosis, there is a need for a dermatology doctor who can observe the symptoms and give an accurate response. Do not rely on do-it-yourself methods, as you may worsen your health condition.
