Skin allergy and sunscreen

Sunscreens-hypoallergenic sunscreens

Sunscreen is the main protection against skin cancer. And since skin cancer is the most common cancer in Denmark, it is important to protect yourself effectively from the sun's harmful UV rays. The fact is that the more sunburns and the higher the lifetime doses of UV radiation, the greater the risk of developing skin cancer.

In their solar campaign the Danish Cancer Society has set up four solar councils:Siestasun hatsunscreenandturn off the solarium. The sun campaign recommends that in Denmark Sunscreen SPF 15 be applied to those parts of the body that are not covered by clothing. And the recommendation is valid even if you just stay directly in the sun for a few minutes. If you have very light skin and/or difficult to tolerate the sun, you can choose an SPF 20 or SPF 30. For very young children and babies it may be appropriate to choose a so-called sunblocker SPF +50.

Sun filters in the sunscreen

There are two sun filters in a sunscreen that protects the skin from the sun, and these two basic sun filters, can be divided intophysicalfilters andchemicalfilters. The two filters work differently:

The physical filters lays on top of the skin, forming a thin, white film or film that reflects the sun's Rays. Examples of physical solar filters are titanium dioxide and zinc oxide.

The chemical filters are chemical substances that penetrate and are absorbed into the outer layers of the skin. Here they absorb the sun's rays and translate them into heat, which is carried away through the blood. Chemical solar filters are available in many different permitted versions. Some protect best from UVA rays, others from UVB rays. Examples of chemical filters are: octocrylene and benzophenone. 

Sunscreens can cause allergies

Just as ordinary moisturizers can cause allergies, you can also get allergies to the ingredients of sunscreens f.ex. perfume substances or preservatives.

The physical filter (titanium dioxide) is not allergenic, while the chemical sun filters can cause allergies in the skin. The chemical sun filters can cause two different forms of allergy:

  • Contact allergy - this type of allergy occurs regardless of whether the chemical solar filter is exposed to sunlight or not. In other words, the allergy occurs when the cream itself and thus the allergenic substance (s) come into contact with the skin. The symptoms(eczema) appears where the skin is in contact with the sunscreen, IE. also in non sunlight exposed places.
  • Photo contact allergy - this type of allergy occurs when the chemical solar filter – after penetrating the skin – is altered by the UV rays in a way that creates an allergenic substance. This allergy therefore requires that the chemical in the product is exposed to sunlight and thus UV-irradiated. The symptoms (eczema) occur where you are in contact with the chemical and at the same time exposed to sunlight.

Multiple allergic reactions

Sunscreens have been a relatively rare cause of allergy, but the fact that more people use sunscreens and that several different manufacturers produce sunscreens, in recent years there have naturally also been more reports of both contact allergy and photo contact allergy. The substances octocrylene, benzophenone-3, benzophenone-10 and ethylhexyl methoxycinnamate are the chemical sun filters most often reported as the cause of allergy.

If the use of sunscreen causes an allergic reaction, it is important to stop its use immediately. One can possibly. choose to be examined by a dermatologist for allergies, to get clarity and advice on which sunscreens are good to use in the future.

If you want to reduce the risk of an allergic reaction, you can use a sunscreen with the physical filter titanium dioxide. However, it should be borne in mind that although titanium dioxide is not allergenic, there may well be other ingredients in the cream in question that can provoke allergies.


If you want to ensure the best possible against allergies - both from physical and chemical sun filters - go for the sunscreens certified by AllergyCertified. In addition to allergenic sun filters, there are unfortunately also many sunscreens that contain substances that are suspected to be endocrine disrupting. When you choose a sunscreen with the AllergyCertified logo, you protect yourself against both allergenic and endocrine disruptors. Likewise AllergyCertified products also do not contain perfume and classified carcinogenic ingredients.

Consumer Council Think

In June 2020, the Consumer Council think made a test of chemistry in sunscreen. Here, the result shows that the solar products certified by AllergyCertified achieve rating A. The a-flask means that the product is a good choice if you want to avoid a number of chemicals of concern. Hos sold exclusively products that are certified by AllergyCertifed including sunscreen. Among allergy-certified sunscreens with the A-flask you will find bl.a. Active by Charlotte I'm hot Sun Spray, Derma Sun lotion and Nile's Earth Face Sun.
