A physician can usually diagnose keratosis pilaris by visually inspecting the skin during a physical examination. Additional diagnostic tests are usually not required.

Because it is hereditary, there is no way to cure or prevent keratosis pilaris. However, it may lessen over time with age.

In some patients, the condition clears up on its own. When it does not, patients may choose to seek treatment for cosmetic reasons. There are several treatments aimed at softening the keratin deposits in the skin to improve its appearance. They include:

• Moisturizing lotions. Dry skin makes the condition worse, so applying moisturizer twice daily is important. Lotions that contain urea help the skin retain moisture and products that contain lactic acid or salicylic acid help to dissolve and exfoliate the keratin. Moisturizer should be applied immediately after bathing.
  
  
• Loofah sponges or brushes. Rubbing the affected areas after a long soak in a hot bath may help to unclog the plugged hair follicles.
  
  
• Topical retinoids. Class of chemical compounds that are chemically related to vitamin A. These drugs regulate skin growth but can be very irritating.
  
  
• Mild peeling agents (alpha hydroxy acids). When applied to the skin, they may open the plugged hair follicles.
  
  
• Antibiotics. In some cases, antibiotics (medications that kill or slow the growth of harmful microorganisms) may be prescribed if the bumps are very red.

Laser hair removal may also be recommended in some cases. In individuals with certain underlying conditions, such as eczema, keratosis pilaris often improves when the underlying disorder is addressed.

Even if the condition clears up with treatment, it is likely to recur. As a result, treatment must be continued regularly. A patient’s treatment for keratosis pilaris may continue for several years.

It is important to note that individuals with keratosis pilaris should avoid scratching the affected area. This can injure the bumps, leaving them open to infection.
