Keratosis pilaris is defined by a bumpy rash that forms on the back of the arms, front of the thighs, buttocks and cheeks. The rash can affect individuals of all ages, but often worsen during the teenage years. There is also a tendency for the condition to run in families.
The condition is triggered by the accumulation of keratin which blocks the pores. This causes the base of the pores to enlarge. This results to irritation of the area bordering the pores and often ensnares the hair. The pressure within the pores can weaken the lining and lead to the shrinking of the sebaceous gland.
Keratosis pilaris appears as miniature, hardened bumps where the skin surrounding them is reddened. It can form in any region of the body excluding the palms and soles, but most often on the:
- Back region of the arms
- Front of the thighs
Management of ketosis pilaris
There is no available treatment for keratosis pilaris. Nevertheless, there are drugs and other measures that can make it less noticeable or annoying.
Luckily, the condition later improves on its own in the late teenage years. Since the rash worsens if the skin is dry, it is vital to keep the skin properly hydrated.
Some of the prescription drugs that include exfoliants such as salicylic acid, urea and lactic acid are also useful.
In case the rash is severely irritated, the doctor might suggest a topical steroid to be used briefly until the irritation improves.
