More than one in ten people can not enjoy the summer and the sun to the fullest due to a sunshine allergy. The UV light quickly causes allergic reactions on the skin, the affected areas turn red and itchy. Especially at the beginning of summer, the annoying skin reaction occurs more and many sufferers wonder how to prevent a sun allergy. There are a number of measures that can be taken prophylactically before sunbathing, but ultimately only a dermatologist can tell you if you are actually suffering from a sun allergy.

These measures can prevent

There are several ways to prevent a sun allergy:

  • Slowly get used to sunlight
  • sun protection
  • suncream
  • Medicines, vitamin supplements and calcium
  • Schüssler salts and homeopathic remedies
  • phototherapy
  • photochemotherapy

Sunscreen and sunscreen

The right sunscreen is the best way to prevent sun allergy. Allergic persons should be sunscreened with a sunscreen of at least 50 SPF before going to the sun. Regular creaming extends the protection. Even in the shade, in the water or under umbrellas you are not protected from the intense sun rays, which is why it is a misconception that you can only develop a sun allergy in the blazing sun.

Also, the clothing does not provide complete protection against UV radiation, however, there are meanwhile detergents which make the textiles more impervious to water after repeated washing. Even black clothing allows less sun rays on the skin. Nevertheless, the best sunscreen is still a good sunscreen with high SPF and the bright sun, especially at noon as possible to avoid.

These medications prevent

There are a number of medicines that can be taken to prevent sun allergy. These include calcium, vitamin D3, beta carotene and antihistamines. The intake of these preparations may be useful for persons who react to violent skin rashes on solar radiation. It should be noted that the preventive ingestion should be started weeks before the skin is increasingly exposed to the sun's rays. Since some drugs interact with other medicines or alcohol, a doctor or pharmacist should always be consulted before taking it.

Calcium weakens the allergic reaction to the sun's rays by binding and breaking down the inflammatory messenger histamine. Vitamin D3 can also help in the case of sun allergy since photosensitive people usually have a deficiency of this vitamin. Beta-carotene is a natural plant pigment found mainly in carrots, spinach and kale. It is a precursor of vitamin A, which is stored in the skin and protects it from the dangerous UV radiation.

Antihistamines are antiallergic drugs that prevent the release of pro-inflammatory messengers in the body. Antihistamines can be taken not only in acute allergic complaints, but also preventively with known sun allergy. In general, these preparations are well tolerated, but it can cause fatigue. Therefore, these drugs are best taken in the evening.

  • Vitamin D

Calcium helps so well

Calcium is a great way to protect yourself from a sun allergy. However, the intake of the mineral should already take place several weeks before the holiday or the increased sun exposure. In a sun allergy, the body is allergic to the UVA waves contained in the sunlight and subsequently releases the tissue hormone histamine. Histamine acts as a messenger of the immune system and leads to an inflammatory reaction: the skin swells, itches and reddens. Calcium helps with allergic skin reactions because it binds and breaks down the histamine in the body.

Calcium preparations show a very good efficacy in photodermatoses and allergic skin reactions, which is why the use for the prevention of sun allergy is recommended. Calcium is administered in the form of tablets. The dosage is usually 1000 mg. When taking it should be noted that there is no overdose, as otherwise, for example, kidney stones can form as a side effect. The best way to discuss the exact intake with a doctor or pharmacist.


Homeopathic remedies can also be effective in preventing sun allergy. However, this is by no means an alternative to a sunscreen with a high SPF! The intake of homeopathic remedies should start about two weeks before the increased sun exposure. Preparations with Muriaticum acidum or Calcium carbonicum contribute to a milder reaction in the case of a sun allergy or even to a lack of reaction.

  • Homeopathic medicines

These vitamins can help

Certain vitamins can help prevent sun allergy. Vitamin D is formed in the skin with the help of sunlight and has a protective effect against skin diseases and allergies. People who suffer from a sun allergy often have low levels of vitamin D in their blood, and vitamin deficiencies increase allergic symptoms. This is a vicious circle, since on the one hand the production of vitamin D in the body is dependent on sunlight, on the other hand the sunlight leads to allergic reactions to skin reactions. As a result, sun allergy consciously avoid the sun and thus can not produce enough vitamin D. It is therefore best to have your doctor determine your vitamin D status in the case of a sun allergy. In case of deficiency substitution of vitamin D in the form of capsules is possible.

Vitamin A also has a protective effect on the skin and ensures that skin lesions that have arisen due to a sun allergy are restored more quickly. Vitamin A can be taken preventively already several weeks before the beginning of intensive sun exposure. In order to avoid overdoses, the vitamin status should also be tested here.

  • Vitamin D

These Schüssler salts can prevent

Schüssler salts can help with a sun allergy and have a preventative effect. Already weeks before the intense sun exposure must be started with the ingestion. These salts of Schüssler may help to prepare the skin for the sun: No. 3 Ferrum phosphoricum, No. 6 Potassium sulfuricum, No. 8 Sodium chloratum, No. 10 Sodium sulfuricum. Each of the tablets is taken 3x3 daily.

home remedies

The best home remedy for preventing a sun allergy is the slow acclimation to the UV rays. If you start sunbathing slowly and extend the duration of sun exposure for several minutes every day, you have a good chance that an allergic reaction will not occur. Especially at the beginning of the holiday or in the first warm spring days sun allergic should be careful, since the skin is still hibernating and not used to the sun's rays. Sunscreen with UV protection is an absolute must before sunbathing. It should not be forgotten that the UV rays can penetrate through window glass. The same applies to stays in the shade, you also have to cream here, because the UV rays are reflected from the ground and therefore omnipresent.


In a sun allergy, the combination of a sunscreen with an antioxidant, such as vitamin C or vitamin E, may be useful. Antioxidants protect the skin from free radical damage caused by sunlight. In most cases, these substances are contained directly in the sunscreen and do not need to be fed extra.


In most people, the sun allergy occurs especially at the beginning of sun exposure, ie in the first warm days or at the beginning of the summer vacation. Often, just those parts of the body are affected by the allergic reaction, which is rarely exposed to the sun's rays (for example, the insides of the forearms, décolleté and shoulders). Slowly getting used to the sun can help prevent sun allergy. Therefore, people with sensitive skin is recommended not to go immediately into the blazing sun, but initially to stay in the shade. Gradually, then the time can be extended in the sun.


In people who suffer from a strong sun allergy, the use of a so-called phototherapy (also known as light-curing) may be useful to the dermatologist. The doctor irradiated the skin over several weeks daily for a short time with UV-B radiation. The light therapy is performed in strictly controlled doses, which are increased over time. As a result, the skin is slowly getting used to the sun and the allergic reaction is mitigated or completely prevented.


For very severe allergies or extremely light-sensitive individuals, the doctor may enhance phototherapy by combining them with the administration of certain medicines that suppress the immune system. This relatively new approach to treatment is called photochemotherapy and is only used if none of the therapies mentioned before has had any effect.
