Causes of acne in adults

Acne on the knees
The main reason, according to experts, is that the area of ​​the elbows and knees contains the roughest skin. These places often experience heavy stress, and as a result, rashes form that begin to hurt and itch.

When rashes appear, it is necessary to take this aspect into account, since such phenomena never happen just like that. One should not think at all that this is necessarily an internal call that urgent treatment is needed, or that the problem is only a disruption in the functioning of some organ. However, it is still necessary to find out why the irritation appeared.

Often the reasons for this phenomenon may be the following factors:

1. Allergy. As one of the most common causes of pimples on the elbows and knees, a child may have an allergic reaction. The child may have eaten a product that contains an ingredient to which he is allergic, or it may be due to synthetic clothing. Sometimes allergies can lead to dermatitis, however, this does not happen everywhere. As a rule, pimples appear not only in the area of ​​dry skin of the elbow or knee, but also just above it. They can be quite small, but at the same time constantly itch and this bothers their owner. In this case, experts recommend undergoing an allergen test to identify the exact cause of acne.
2. Sedentary lifestyle and mechanical stress.
   With a sedentary lifestyle, a person can accidentally cause a rash on the skin due to the fact that friction against various surfaces constantly occurs. There is a high probability that a similar problem may arise among people whose work involves paperwork. As a result of constantly placing your hands on the table, invisible and small pimples may appear.
3. Psoriasis. This disease can be the main cause of pimples. Typically the rash does not involve the knee, but the elbow is often involved. Sometimes the skin begins to peel and fall off after a while.
4. Insect bites. Pimples on the legs and arms are often caused by bites such as mosquitoes or ticks. The body thus begins to resist the foreign object, in this case the small insect poison. Quite often, irritation goes away on its own if you apply a small amount of soothing cream.
5. Hypothermia or overheating.
6. Exhaustion of the body.
7. Various diseases related to the intestines or stomach.

Rashes and their causes

In fact, there can be a large number of reasons. For example, sometimes rashes occur due to mechanical stress when tight or uncomfortable shoes are used. As a result, the knees:

• Blush;
• Rubbed;
• Covered with a small red rash.

A rash may appear after an insect bite. As a result, the person feels itching and begins to scratch the wound vigorously. Thus, some kind of infection may occur. When ticks bite, a hemorrhagic rash may well appear.

Another common cause may be a fungus. For example, mycosis refers to a rash on the feet due to parasitic fungi. The onset of such a disease is associated with the appearance of a watery rash and some cracks that appear among the toes. Then the skin particles begin to peel off and even purulent ulcers appear where there were initially blisters.

If we are talking about scabies, the rash is accompanied by severe itching. This happens because the scabies mite moves under the skin. When there is lichen, blisters may also appear.

When a rash is caused by allergic reactions, it is often associated with the use of cosmetics or certain detergents that have an allergenic effect. Reactions can be caused by fur, for example. Itching occurs due to dust mites and bed bugs. Food allergies caused by citrus fruits, chocolate, dairy products and so on are common.

Finally, we should not forget about urticaria as a possible cause of rashes. In this case, the rash may appear and then appear. Subsequently, the rashes become blisters - almost the same as those that can occur if a person is burned by nettles.

Doctors pay considerable attention to the hereditary causes of the rash. It could be eczema, for example. It usually causes bubbles containing liquid inside. Then they begin to burst and are replaced with dry crusts.

During diabetes, there may be itchy skin along with a rash on the knees. If normal blood sugar levels are restored and stabilized, the rash usually disappears.
