Allergy contact

With contact eczema, contact with certain substances leads to a rash (eczema). There are two types of contact dermatitis:

Allergic contact dermatitis

Irritant contact eczema

Sometimes these two types of contact dermatitis can occur at the same time.

Allergic contact dermatitis

In allergic contact eczema, the cause of eczema is an “allergic reaction” to a certain substance. You will only receive it if you have become allergic to a certain substance after previous skin contact. This substance is known as an “allergen”. Once you are allergic, a little allergen is enough to cause skin pain. A contact allergy often lasts for life.

Irritant contact eczema

Irritant contact eczema develops eczema from irritation, for example from contact with water, soap, detergent and the like, from rubbing or from being cold. Therefore, anyone can develop irritating contact dermatitis. However, irritation occurs earlier in one than the other. With a lot of contact with water, eczema develops faster and more heavily. It is therefore not an allergic reaction. Find out more about contact allergies or read the allergy brochures.

Hand eczema

The term eczema is used for skin lesions that are associated with itching, redness, small bumps (papules), blisters, peeling, and sometimes fluid discharge. These phenomena are the result of an inflammatory reaction of the skin. The inflammation of eczema is not caused by bacteria or fungus, so it is not contagious. Some forms of eczema can be very difficult to treat and last a long time. Various factors play a role in most forms of hand eczema. These factors can act on the skin both externally and internally.

Nummular eczema

Eczema is a collective term for skin conditions that are characterized by red, scaly patches. Eczema is based on a superficial inflammatory reaction of the skin, for which several causes are possible. Nummelekzema is characterized by round, itchy patches on the skin that usually appear symmetrically on the arms and legs. It occurs mainly in adults and is not contagious.

Seborrheic eczema

Seborrheic eczema is a skin condition – with redness and flaking – that occurs primarily on the face and hairy head. Seborrheic dermatitis occurs in about 5% of the population, slightly more common in men than women. The condition usually develops at the beginning of puberty and is not contagious. It rarely occurs in children, except in small children (“mountain”). This condition is not related to internal diseases. The course of seborrheic eczema is variable, with periods of rest alternating with times when the skin disease is more active. Eczema can be treated well, but may return after treatment is stopped.

Constitutional eczema

Atopic eczema, also called atopic eczema, is a form of eczema that occurs mainly in childhood. Eczema usually starts before the age of two and is mainly characterized by severe itching. Constitutional eczema is often associated with a predisposition to develop allergies. This predisposition is hereditary and is called atopy. If eczema develops in infancy, there is a good chance it will go away on its own later in life. However, eczema can persist chronically or come back later.


Rosacea is a common chronic skin condition of the face that mainly affects middle-aged women. The four main signs are redness, small enlarged blood vessels (rosacea), bumps (papules), and pimples (pustules). Eye abnormalities are common in rosacea and can range from mild to severe. The disease can be treated well (better said: it can be suppressed), but it is rarely finally curable.


Acne vulgaris, commonly known as acne, is the medical name for pimples. Almost everyone has acne during puberty. In one case it is a few pimples, in the other it is a widespread skin disease that can cause many psychological problems and impair the enjoyment of everyday life. Sometimes acne can persist after puberty or only start in adulthood.

Age wart (verruca seborrhoica)

A verruca seborrhoica (fat wart, old age wart, wisdom wart …) is a completely benign wart-like area that develops in adulthood and often appears on the trunk or face. It can be colored from light to dark brown. Read more about age warts.

Aged warts are benign types of skin that are very common, especially in the elderly (over 50 years old). They increase with age. By the age of 30 you usually have a few. How the older you get, the more appear. Hence the not so flattering name of age wart (verruca senilis).

Another name that is commonly used is verruca seborrhoica (fatty wart). The English term is seborrheic Keratosis or seborrheic wart).

Skin diseases

A skin disease or problem can be very annoying and negatively affect your life. Fortunately, something can often be done about it. A skin disease is a disease or abnormality of the skin caused by bacteria, fungi, viruses, allergies, drugs, radiation, metabolic disorders, or some other cause. There are many different skin diseases. They can often be recognized by spots, bumps, or flakes on the skin.
