- Keratosis pilaris is a very frequent condition:
- It presents as follicular scaly papules affected all areas except the glabrous skin but mostly found on the arms, legs and buttocks.
- These lesions are painless but may be red and itchy at times.
- It is associated with Atopy and Ichtyosis Vulgaris:
- Both conditions are characterized by a deficiency of filaggrin, a corneal protein.
- Atopic dermatitis is more frequent in Asia affecting around 8% of the urban population in S.Korea(http://adv.medicaljournals.se/article/pdf/10.1080/000155500459295).
- Keratosis pilaris is caused by an excess keratin production:
- The excess keratin surrounds and entraps the hair follicles in the pore.
- This causes the formation of hard plugs (process known as hyperkeratinization).
- Practically speaking, the most important part is education and good counselling so the patient understands the the nature of keratosis pilaris (KP):
- Keratosis pilaris is not curable, but it may become less noticeable with time.
- KP may spontaneously clear without treatment.
- KP generally requires ongoing maintenance therapy
- Treatment is as wide as it is unsatisfactory :
- urea cream up to a concentration of 15%, Tretinoin cream to remove the hyperkeratosis.
- Alpha Hydroxy-acids (AHA) chemical peels.
- To temporarily reduce redness but not roughness, pulse dye laser treatment or intense pulsed light (IPL) can be done.
