Keratosis pilaris is a very common skin condition that is characterized by bumps located at the back of the arms. This condition is often called as chicken skin since the bumps that are small and rough resemble it.
This condition can also appear on the buttocks and thighs, but primarily occurs at the back of the arms.
The whole body can also be susceptible to this condition except for the palms and soles.
The bumps on the back of the arms are often mistaken for pimples and usually get worse during cold winter months or when the skin gets dry.
The bumps can also be seen on pregnant women and also show up after childbirth.
This condition comes in several types and variants. There are also other disorders that are linked to it.
Bumps on Back of Arms Causes
The primary and exact cost of keratosis pilaris is still unknown.
Experts believed that hyperkeratinization or the overproduction of keratin on certain parts of the skin can cause keratosis pilaris. When overproduction happens, there is a slow thickening and plugging in the follicles of the hair in the skin which can cause small superficial blood vessels to dilate.
When this happens the skin eventually takes a flushed appearance with tiny bumps.
Genetics. Bumps that are found on the back of the arms are partly caused by genetics. It has been studied that majority of the patients that have the bumps also have family members that have the same condition.
Some underlying causes that can trigger the onset of keratosis pilaris include hypersensitivity reactions and dry skin.
The bumps are also closely associated with other skin conditions like icthyosis vulgaris, skin allergies, rhinitis, asthma, seasonal allergies, atopic dermatitis and eczema.
Bumps on Back of Arms Treatment
Since the condition is considered to be caused by genetic predisposition, there is no known cure for it. Typically the severity of the condition varies from one patient to another. Treatments that are available will help in controlling the symptoms.
For mild conditions of keratosis, using a loofah sponge or a sponge harvested from a certain type of gourd and lotions that deeply moisturize the skin can help. Patients can also use a moisturizing soap together with the lotion and sponge for effective results. It can help if these will be applied in a regular basis.
Dermatologists would often recommend creams that contain Retin-A.
Moisturizing products that contain salicylic acid can aid in removing symptoms of keratosis pilaris. Those that have vitamins can also help.
Bumps can be removed by humidifying the bedroom or the place where the patient spend most of his or her time.
