Sun Allergy: Rudolph Care’s Guide to Sun Protection
Rudolph Care’s guide to sun allergy gives you insight into how to best care for your skin with gentleness and attention if it reacts to the sun’s strong rays.
In this guide, we have gathered information about what actually happens in the skin, how to prevent the reaction, and how to build a sun routine that both protects and nourishes your skin.
What is sun allergy?
Sun allergy, also known as polymorphic light eruption (PMLE), is a hypersensitivity reaction triggered by sunlight exposure.It appears as red bumps, patches, itching, discomfort, or a burning sensation in the skin.
The reaction can occur shortly after sun exposure. The body simply responds to sunlight by triggering an immune response in the skin, which causes inflammation. You do not need to be sunburned or burned for sun allergy to occur.
Sun allergy typically appears on areas of the body that are suddenly exposed when the weather changes and the sun returns after long winter months. This can include the chest, shoulders, or forearms. The face can also be affected, but this is less common. The reason is that facial skin is exposed to sunlight year-round and is therefore usually more adapted.
For most people, symptoms subside after four to seven days when the skin gets a break from the sun. However, many experience that the reaction returns year after year. That is why it is important to know what you can do to prevent sun allergy.
Who suffers from sun allergy?
Anyone can develop sun allergy, but it is more common among people living in countries with less sunlight. Skin that has had limited sun exposure for many months is not adapted to intense or sudden UV radiation. Having a light skin type may also increase the risk of sun allergy.
Prevent sun allergy: Four tips for your sun routine
At Rudolph Care, we believe that the best approach to sun allergy is prevention. It is not necessarily about avoiding the sun, but about meeting it with care and protecting your skin.
- 1. Gradually adapt your skin
Start with shorter periods in the sun early in the season and allow your skin time to adjust to sunlight. Many people find that the skin reacts more mildly throughout the summer once it finds its balance again. - 2. Always use sunscreen – more rather than less
Apply sunscreen to all exposed areas. Remember to apply it 30 minutes before sun exposure. It is also important to reapply after swimming, sweating, or towel drying. - 3. Choose broad-spectrum protection
A good sunscreen protects against both UVA and UVB rays, as both types can cause sun allergy – although most cases are linked to UVA radiation. All sun products from Rudolph Care contain five chemical UV filters approved by the Nordic environmental label Nordic Swan Ecolabel, providing broad-spectrum protection against both UVA and UVB rays. Chemical filters means, in short, that we have full knowledge of the ingredients and how the finished product works. - 4. Seek shade when the sun is strongest
The sun’s rays are strongest between 12 and 3 PM. It is therefore a good idea to stay in the shade during this time – but still wear sunscreen, as UV rays are reflected even in the shade. Find a comfortable chair, wear a sun hat, and enjoy a summer book during your sun break.

Caring for your skin after sun exposure
At Rudolph Care, we believe that a hydrating post-sun routine is just as important as protection during sun exposure. For sensitive skin that reacts easily to the sun, this is an essential part of a complete sun care routine.
Even if you have used sunscreen carefully, your skin may still feel dry and dehydrated after a day in strong sunlight. That is why it is important to care for your skin with the right products after sun exposure.

What to do if sun allergy has already appeared
If your skin has already reacted to the sun, the most important thing is to give it rest. You can do this by keeping it out of direct sunlight.
You can cool the skin with a damp cloth or take a cool shower. Afterwards, moisturize the skin with a gentle, fragrance-free cream. This helps support and soothe the damaged skin barrier.
Seek medical advice if symptoms do not improve or if they spread. In severe cases, medical treatment may be necessary.
FAQ – Sun allergy
How do you get rid of sun allergy quickly?
The most important thing is to let the skin rest and avoid the sun. You can gently cool the skin with a damp cloth or a cool shower. Afterwards, moisturize with a gentle, fragrance-free cream.
If there is no improvement, consult a doctor.
How long does sun allergy last?
Most people experience improvement within four to seven days when the skin is protected from sunlight. After that, it is important to slowly reintroduce sun exposure so the skin can adapt again.
What is the difference between heat rash and sun allergy?
Heat rash occurs when sweat blocks the sweat ducts, causing small itchy bumps. It typically appears in areas where the skin gets warm or where clothing rubs against the skin. Sun allergy is an immune reaction triggered by sunlight exposure on UV-exposed areas.
Why do you suddenly get sun allergy?
Sun allergy often appears suddenly because the skin has not been exposed to sunlight for a longer period. After winter, the skin is not prepared for strong UV radiation, and the immune system reacts. The difference between weak winter UV levels and strong spring sunlight is especially noticeable in northern countries, which can trigger the reaction.
