Keratosis Pilaris: Symptoms, Causes, and Treatment — DermNet

Rough and bumpy skin texture is often caused by a build-up of dead skin cells that eventually clog up your pores (also known as hair follicles). In the case of keratosis pilaris, dry patches and pimple-like bumps are caused by a build-up of the skin protein known as keratin. When this happens, the opening of the hair follicle becomes blocked, and these “plugs” can lead to areas of uneven skin texture.

Body bumps are one of the most common concerns I hear from patients. Sometimes it can be hard for people to tell if it’s acne or keratosis pilaris — but skin type and location of the bumps are two key things dermatologists look for. I created my two SLMD Skincare body regimens — Body Acne System and Body Smoothing System — to provide everyone with effective treatments.

Keratosis pilaris

It’s not yet clear why certain people are more predisposed to this keratin build-up than others, but many dermatologists believe that these bumps may be genetic. For teenagers, it’s also possible for hormones to spark keratosis pilaris flare-ups around the time of puberty. Most cases of keratosis pilaris will clear up on their own with age.

Remember that about 90% of your skin’s outermost layer is made up of dead, flattened cells called corneocytes (aka “old” keratinocytes), bound tightly together to form a protective defense. Those cells contain a protein called keratin, which provides the structure and rigidity of the skin barrier.

What is the rec­om­mend­ed treat­ment for KP?
Treat­ment of Ker­ato­sis Pilaris is not med­ical­ly nec­es­sary; how­ev­er, many peo­ple with this con­di­tion choose to seek treat­ment for cos­met­ic rea­sons. A com­mon ini­tial treat­ment of Ker­ato­sis Pilaris is inten­sive mois­tur­iz­ing. This may help with the dry­ness, but usu­al­ly does not clear up the bumps. Treat­ment rec­om­mend­ed for mod­er­ate to severe cas­es of KP are top­i­cal lotions or creams con­tain­ing urea (Car­mol 10 or 20) or lac­tic acid (i.e. AmLactin or Lac-Hydrin), and top­i­cal retinoids. Mild peel­ing agents (alpha-hydroxy acids and skin-smooth­ing scrubs) are the most effec­tive in open­ing the clogged hair fol­li­cles by remov­ing the excess keratin.

Keratosis Pilaris and Variants

Keratosis pilaris is usually easy to recognize based on its location on the body and the characteristics of the bumps. We’ll share the common characteristics, but before we do, we want to say the information we share here shouldn’t replace qualified care from a licensed dermatology provider or medical provider. Your healthcare provider is the one who will make the official diagnosis. If you’re experiencing bumps—be it keratosis pilaris or something else—and they become painful or don’t clear up on their own, or you have other symptoms, it’s important to see your medical provider.

Can KP be com­plete­ly cured?
Unfor­tu­nate­ly, there is no known cure for Ker­ato­sis Pilaris. Although the con­di­tion may remain for years, symp­toms usu­al­ly lessen by age 30. Rec­om­mend­ed treat­ment for KP are main­ly for the tem­po­rary relief of symp­toms, but may lessen the vis­i­bil­i­ty and tex­ture of the bumps. Results will vary from per­son to per­son, which sim­ply means that what may work for one per­son, may not work for another.

Pseudomonas folliculitis, or “hot tub” folliculitis, typically occurs after exposure to contaminated bodies of water such as swimming pools, hot tubs, water slides and sometimes even freshwater sources. The pseudomonas bacteria thrives in heated, moving water where chlorine and pH levels are imbalanced. Symptoms of this infection include itchy, red bumps that may be filled with pus and appear within hours to days after exposure.

If you struggle with the tiny red bumps associated with keratosis pilaris, you’re certainly not alone. Approximately 40% of adults and 50 to 80% of adolescents will develop this skin condition at some point throughout their lives. 1 Keratosis pilaris is categorized as areas of rough and bumpy skin that occur when a build-up of dead skin cells clogs the opening of the hair follicles. These clogged hair follicles result in a sandpaper-like texture and patches of rough, sometimes discolored skin, with groups of painless, pimple-like bumps. Keratosis pilaris bumps are considered benign and are not contagious.
