Jodacne – Causes, Symptoms & Treatment


The term iodine acne refers to a symptom of iodine allergy, a contact allergy. Universally, allergies belong to the autoimmune diseases. A contact allergy is cured with an appropriate healing process.

What is iodine acne?

Iodine acne is a result of an overreaction to iodine . The iodine allergy is counted among the actual allergies , since the iodine itself is undoubtedly an allergy trigger. In the case of allergies, the immune defense system reacts too much to triggering substances and produces corresponding symptoms. Since iodine acne only affects a localized area of ​​skin, but the iodine allergy affects the entire body, the physician describes iodine acne as a local reaction to iodine, but the iodine allergy as a whole is more of a systemic allergy.

The latter is noticeable through symptoms, up to and including allergic shock . In the case of iodine acne, one sees a whole clinical picture in relation to acne as a generic term, but more of a symptom in relation to iodine allergy. Iodine acne is treatable, but it could come back with iodine intake.


Most of this allergic reaction is an overreaction of the body to intense exposure to iodine. This trace element is found in food, table salt and drinking water. In the case of allergies, the body overreacts to allergenic substances, especially since it treats them as germs. An allergy as such is not caused by germs.

In general, an allergy is not uncommon when chronic diseases are present. Many medications can cause allergies. Unhealthy environmental substances are also the cause of hypersensitivity reactions. Such and similar factors can adversely affect the body and thus promote the development of an allergic reaction.

Symptoms, Ailments & Signs

Initially, the affected person expresses several blisters on the mouth. Generally, papules appear on the face. The signs of the disease worsen with the unavoidable frequent intake of iodine with food. These can germinate for the first time, but also again through contact with iodine.

Now it is important to note whether the affected person is currently suffering from allergies or cold sores . If the body is cut off from all contact with iodine, the hypersensitivity reaction will soon subside. Future sequelae are unlikely.

It is true that iodine allergies can be averted by avoiding an allergy-causing substance in the future. However, bleeding from the affected areas on the face can result in infectious wounds. These are triggered by scratching too hard and by using spoiled or contaminated ointments.

Diagnosis & disease progression

Since this complaint is basically a symptom and not an entire clinical picture, the iodine allergy should be considered as a whole. First of all, the naturopath should ask about all the signs that have occurred and involve any significant diseases and underlying diseases in the allergy-related diagnostic interview.

A medical examination is usually carried out in the dermatologist’s office or in a dermatology clinic. A disease detection is created with the inspection of the diseased skin areas and with the exclusion of cold sores at the doctor’s. If necessary, a test for allergenic substances is carried out.


If it is more extensive, iodine acne represents an intolerance or an allergy. This can occur as a result of long-term treatment with iodine or iodine-based contrast media. Iodine acne is usually due to a higher dose of iodine. The contact allergy is evaluated as a real allergy. Further contact with higher doses of iodine can therefore become problematic.In contrast to a local application of iodine, an iodine allergy involves a reaction throughout the body. However, iodine acne usually only affects the mouth and face or a local region of the body. As a complication of acne, boils or inflammation with pus foci can develop. These can leave scars if left untreated.

Therefore, iodine-related inflammation should be treated by a dermatologist, otherwise germs can be spread. In addition, the presence of intolerance or an iodine allergy should be ruled out. In the worst case, this could lead to an anaphylactic shock reaction due to renewed contact with iodine.

Further complications of iodine acne are not to be expected. Nevertheless, it may be advisable to make the diet low in iodine. In the future, those affected should use iodine-free table salt. The problem, however, is that the food industry adds iodized salt to many of the industrially produced foods. The increasing demand for iodization of drinking water could also cause the number of complications to skyrocket.

When should you go to the doctor?

People who experience health problems from consuming products containing iodine should consult a doctor. Iodine is one of the vital nutrients, so that an irregularity in iodine intake should always be clarified. This is the only way to initiate comprehensive medical care and alleviate the symptoms. A change in skin texture is cause for concern.

If wheals or papules appear on the face, if there are pimples or abnormalities in the skin quality, a doctor’s visit is necessary. In case of itching, general discomfort or hypersensitivity, a doctor should be consulted. Adequate wound care is necessary for open wounds. If this cannot be fully guaranteed, pathogens can penetrate the organism and trigger further diseases. In severe cases, blood poisoning can develop, which is life-threatening.

A doctor should therefore be consulted at the first signs, such as pain or the spread of the wound. If there are sensory disturbances, such as numbness or reddening of the skin, a medical examination is advisable. If the optical flaw causes psychological problems, behavioral problems or changes in personality, a doctor or therapist should be consulted. If you have trouble sleeping, have a headache or are withdrawing from social life, you should ask a doctor for help.

Treatment & Therapy

Usually, antibacterial ointments are used to treat iodine acne. It is treated like any other acne. Avoiding iodine intake is important because otherwise, despite treatment, the allergy may flare up again. Jodacne can be remedied in any case, the treatment can be a bit lengthy. Jodacne shows no chronic course.

A healthy lifestyle of the patient is essential for the stabilization of the organ system. Excessive alcohol consumption, smoking and weight problems must be corrected, as these can increase the susceptibility to allergic reactions. Likewise, antibacterial or antiallergic ointments can also have undesirable side effects.

Therefore, they should be carefully selected. Drugs to increase the immune system should be avoided during the acute phase. Desensitization, which trains the immune system to live with the triggering substance in question, is advisable if it succeeds. However, this is expensive and is usually not reimbursed by the statutory health insurers. Avoiding salt and foods that contain iodine can permanently eliminate iodine acne.

Questionable treatment methods, which are not reimbursed by health insurance, can occasionally be ineffective. As a result, these should be carefully considered before use. Help from familiar people, acquaintances or self-help groups is also useful. It can also be advantageous to find out more about iodine allergy and iodine acne on the Internet.

Outlook & Forecast

The prognosis for iodine acne depends primarily on the lifestyle of the person affected. It is also important to avoid the allergen, otherwise treated acne will flare up again due to intolerance. However, iodine acne does not tend to become chronic, so it can be completely eliminated after successful treatment.

Because it is an immune response, avoiding iodine is the best way to improve prognosis. It is sufficient for this to do without foods and substances that contain particularly iodine. There is no need to worry about an underdose of iodine, since iodine is also found in many foods that are not labeled as containing iodine and only contain traces of the substance. As a rule, this normal supply of iodine is completely unproblematic, even for a person who is prone to iodine acne.

Jodacne usually heals after a few weeks or months. Scars can form in areas of skin that are particularly affected, and these scars can also partially heal or at least fade a lot. Permanent limitations and medical problems are no longer to be expected after iodine acne treatment and avoidance of the allergen.


Avoiding the body’s absorption of iodine and good facial care can prevent iodine acne in the long term. Foods containing iodine have labels on their packaging and they also differ in terms of the intensity of the iodine content. Vaccinations against allergies are not available, especially as they would unnecessarily burden the immune system. Whether the acne could also have been caused by other allergy triggers should be explored.

The preventive measure can usually be supplemented by good facial care for acne in general, especially if the skin is already stressed. If the patient has brittle skin or skin that is thinner due to age, it should be moisturized regularly. The statutory health insurers in Germany only reimburse the costs incurred for the treatment of the iodine allergy in the case of acute symptoms or generalized signs of the iodine allergy, less for the treatment of a mere iodine acne.


Antibacterial ointment is usually prescribed against iodine acne. This form of acne is treated like any normal acne. Marigold oil is also used as an alternative to combating the symptoms. In any case, iodine-containing salts and foods should be avoided in the case of iodine acne. This can permanently fix the disease. The patient should also change their lifestyle.

Excessive alcohol consumption, weight problems and smoking should be brought under control, otherwise the susceptibility to allergic reactions increases. It can lead to a decrease in the quality of life and limitations in everyday life for those affected. In this case, it is important that the patient is supported by their family, friends and a psychologist.

It is recommended to wash hands frequently and use special care products for people with iodine acne. It is also an advantage to ask your family doctor about the vaccination against iodine intolerance and, if necessary, to have it administered to you. Due to the many self-help options, those affected are able to alleviate the symptoms of the disease and lead a normal life with it. If the person concerned pays attention to known irregularities and acts quickly, a speedy improvement can be achieved.

You can do that yourself

In addition to treatment with an antibacterial ointment, it is possible that the patient himself can influence his illness or rather its course. Of course, it is important that the intake of iodine is stopped immediately, otherwise the body will not have time to recover from the allergy flare-ups. Treating acne is a long process and skin needs all the support it can get.The patient has a strong influence on the healing with his lifestyle, and thus also his diet, and should also perceive this. A healthy and balanced diet that completely excludes iodine-containing foods is ideal. Such a change requires a lot of research in advance, since iodine is added to many foods in Germany. Pasta made from durum wheat semolina and water, certain types of bread, fruit, vegetables and a range of convenience foods are iodine-free, although of course processed foods do not necessarily contribute to a balanced lifestyle.

The patient should also be careful not to smoke or at least limit cigarette consumption, drink alcohol in moderation and exercise several times a week to prevent weight problems. Being overweight favors allergic reactions.
