Keratosis pilaris is a common, harmless skin condition characterized by small painless bumps on skin forming dry, rough patches. This condition usually affects the upper arms, thighs, cheeks or buttocks and rarely occurs on the face also. Although it is more common in children, it can occur at any age. In most cases the condition subsides once the children get older.
Keratosis pilaris is caused by a build up of keratin, the skin protein. The excess keratin produced starts to accumulate in the hair follicles on skin resulting in plugging of pores. This prevents the escape of dead skin cells through the pores. These dead cells and accumulated keratin leads to formation of small bumps on skin.
The exact reason behind the build up of keratin is not known but however it may occur in association with some skin conditions, such as atopic dermatitis/eczema. Other possible causes of Keratosis pilaris are deficiency of Vitamin A, genetic diseases and hormonal imbalances. People with dry skin are more susceptible to get Keratosis pilaris. During cold season, the symptoms may get worsened as the atmosphere lacks moisture.
Usually Keratosis pilaris doesn’t require any treatment. If you are conscious about the appearance or if you experience any discomfort like severe itching, consult a dermatologist. The physician can diagnose Keratosis pilaris by simply observing the skin closely. Although there is no proper cure for this condition, regular use of moisturizing lotions/creams may help to lessen the symptoms.
