| Meta Canonical | null |
| Boilerpipe Text | Keratosis pilaris is a common cause of bumps on the arm. These bumps are harmless and may look like goosebumps or chicken skin. However, if the bumps are itchy, this may point to eczema, folliculitis, or heat rash.
A person may not need treatment for the bumps on their arms unless they develop any bothersome symptoms, such as dryness or itchiness.
Keep reading for more information about health issues that commonly cause bumps on the arms.
These bumps contain extra keratin, which is a protein in the hair, skin, and nails. A buildup of dead skin cells contributes to the issue.
The bumps are usually skin-colored. They
may look
red on lighter skin or brownish-black on darker skin tones, and they can sometimes be itchy.
A person is most likely to notice the issue when the skin is dry, such as during winter months. The bumps may disappear during warmer or more humid seasons.
In older children and adults, keratosis pilaris typically
appears on
the upper arms, thighs, and buttocks. In younger children, the bumps usually form on the cheeks, but they can also appear on the arms and thighs.
About
50–80%
of adolescents and at least 40% of adults may have keratosis pilaris. However, these estimates are likely low, as people often do not report the issue to their doctors.
Some factors that increase a person’s chances of developing keratosis pilaris
include
:
a family history of the issue
generally dry skin
hay fever
asthma
ichthyosis vulgaris
, a condition that causes dry skin
eczema
(
atopic dermatitis
)
obesity
or overweight
Down syndrome
being female
A person with keratosis pilaris can take some steps to prevent bumps from forming. The
AAD
recommends:
using a thick, oil-free moisturizing cream
moisturizing immediately after bathing, while the skin is still damp
using moisturizer whenever the skin feels dry
considering
hair removal techniques
other than shaving or waxing, which can make keratosis pilaris worse
limiting showers and baths to once a day and keeping them short
avoiding bar soap in favor of a mild cleanser
using a
humidifier
if the skin is dry
avoiding self-tanners
While keratosis pilaris is the most common cause of bumps on arms, there are other possible causes.
Itchy causes
Eczema
can form red, itchy patches or small, liquid-filled bumps that eventually crust over.
Heat rash
often causes redness, itchiness, or tingling.
Folliculitis
is the infection of hair follicles, which can form tender, red, pus-filled bumps — typically on areas that are shaved or exposed to frequent irritation.
Psoriasis
is an inflammatory skin condition in which excessive skin cell growth leads to thick plaques of skin that may be dry, scaly, and raised.
Contact dermatitis
causes a bumpy rash that can be itchy and otherwise uncomfortable.
Non-itchy causes
Bumps on the arms that are not itchy may point to acne.
Acne
can cause
whiteheads
or
blackheads
, and they
develop when
a person’s pores get clogged with:
dead skin cells
bacteria
oil
Doctors can recommend some ways to help relieve any itchiness and reduce the bumpiness of the skin.
Exfoliation
The
AAD
recommends taking the following steps to treat keratosis pilaris:
Gently
exfoliate the skin
to remove dead skin cells.
Apply a chemical exfoliator, also known as a keratolytic.
Use an oil-free moisturizer liberally.
They also provide the following advice for managing keratosis pilaris:
make sure not to scrub the skin harshly
use the keratolytic only as directed
apply the moisturizer after using the keratolytic, after bathing, and whenever the skin feels dry
Medications
Doctors
may prescribe
or recommend an over-the-counter ointment or cream that contains one of the following ingredients:
lactic acid
alpha hydroxyl acid
salicylic acid
retinoids
glycolic acid
urea
These medications help get rid of dead skin cells. A doctor may also recommend creams or lotions to help with moisturizing the skin.
One
study
suggests that a combination of natural glycolic acid and salicylic acid may be the best way to restore the skin’s texture. Indeed, 70–80% of participants who used the combination saw smoother skin with less oiliness and a more even texture.
If other treatments fail, a doctor may recommend
laser therapy
to reduce the bumps and any discoloration.

Only a
dermatologist
can diagnose the cause of bumps on the arms.
They will ask about general health, family history, and any other symptoms, and
examine
the affected skin.
For people with any of the following, it may be a good idea to contact a doctor:
itchiness
dryness that causes discomfort
a displeasing appearance of the skin
concerns about the underlying cause
It is especially important to receive professional attention if home care techniques are not working.
Also, see a doctor if a rash and a
fever
are present, as these can be symptoms of a more serious
infection
.
Below are some commonly asked questions about bumps on arms.
Why might a person be getting bumps on their arms?
A person may be getting bumps on their arms due to the following:
keratosis pilaris
eczema
heat rash
folliculitis
psoriasis
contact dermatitis
What triggers keratosis pilaris?

happens when
a person’s hair follicles become blocked with a buildup of keratin, a substance found in skin, hair, and nails. The cause of this is unknown, but researchers believe that families carry the condition.
How can a person get rid of keratosis pilaris on their arms?
A person may be able to get rid of keratosis pilaris by gently
exfoliating the skin
to remove dead skin cells.
Alternatively, a doctor
may prescribe
or recommend an over-the-counter ointment or cream that contains ingredients such as lactic acid, salicylic acid, or retinoids.

mistaken for
:
folliculitis
eczema
acne
milia
scurvy
In many cases, bumps on the arms result from keratosis pilaris, a benign condition that usually requires no treatment.
Certain home care techniques can help reduce the bumps and any associated symptoms.
A doctor can recommend professional treatments if these methods are ineffective and the bumps are causing discomfort. |

Keep reading for more information about health issues that commonly cause bumps on the arms.
## [Pictures]()
## [What is keratosis pilaris?]()
[Keratosis pilaris](https://www.medicalnewstoday.com/articles/318746) is a common cause of bumps on the arms. This benign skin condition [may form](https://dermnetnz.org/topics/keratosis-pilaris) dry, rough patches or resemble [goosebumps](https://www.medicalnewstoday.com/articles/goosebumps-on-skin), [pimples](https://www.medicalnewstoday.com/articles/71702), or a [rash](https://www.medicalnewstoday.com/articles/317999).
These bumps contain extra keratin, which is a protein in the hair, skin, and nails. A buildup of dead skin cells contributes to the issue.
The bumps are usually skin-colored. They [may look](https://www.nhs.uk/conditions/keratosis-pilaris/) red on lighter skin or brownish-black on darker skin tones, and they can sometimes be itchy.
A person is most likely to notice the issue when the skin is dry, such as during winter months. The bumps may disappear during warmer or more humid seasons.
In older children and adults, keratosis pilaris typically [appears on](https://www.aad.org/public/diseases/a-z/keratosis-pilaris-symptoms) the upper arms, thighs, and buttocks. In younger children, the bumps usually form on the cheeks, but they can also appear on the arms and thighs.
According to the [American Academy of Dermatology (AAD)](https://www.aad.org/public/diseases/a-z/keratosis-pilaris-causes), the condition often develops before a child turns 2 years old or during the teenage years.
About [50–80%](https://www.ncbi.nlm.nih.gov/books/NBK546708/) of adolescents and at least 40% of adults may have keratosis pilaris. However, these estimates are likely low, as people often do not report the issue to their doctors.
Some factors that increase a person’s chances of developing keratosis pilaris [include](https://www.aad.org/public/diseases/a-z/keratosis-pilaris-causes):
- a family history of the issue
- generally dry skin
- [hay fever](https://www.medicalnewstoday.com/articles/160665)
- [asthma](https://www.medicalnewstoday.com/articles/323523)
- [ichthyosis vulgaris](https://www.medicalnewstoday.com/articles/318242), a condition that causes dry skin
- [eczema](https://www.medicalnewstoday.com/articles/14417) ([atopic dermatitis](https://www.medicalnewstoday.com/articles/323493))
- [obesity](https://www.medicalnewstoday.com/articles/323551) or overweight
- [Down syndrome](https://www.medicalnewstoday.com/articles/145554)
- being female
Keratosis pilaris is also [associated with](https://www.ncbi.nlm.nih.gov/books/NBK546708/) [diabetes](https://www.medicalnewstoday.com/articles/323627), [Noonan syndrome](https://www.medicalnewstoday.com/articles/179200), and [malnutrition](https://www.medicalnewstoday.com/articles/179316). It [may be](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8842679/) a side effect of vemurafenib, a medication that can treat [melanoma,](https://www.medicalnewstoday.com/articles/154322) too.
A person with keratosis pilaris can take some steps to prevent bumps from forming. The [AAD](https://www.aad.org/public/diseases/a-z/keratosis-pilaris-self-care) recommends:
- using a thick, oil-free moisturizing cream
- moisturizing immediately after bathing, while the skin is still damp
- using moisturizer whenever the skin feels dry
- considering [hair removal techniques](https://www.medicalnewstoday.com/articles/hair-removal) other than shaving or waxing, which can make keratosis pilaris worse
- limiting showers and baths to once a day and keeping them short
- avoiding bar soap in favor of a mild cleanser
- using a [humidifier](https://www.medicalnewstoday.com/articles/322228) if the skin is dry
- avoiding self-tanners
## [Other causes of bumps on arms]()
While keratosis pilaris is the most common cause of bumps on arms, there are other possible causes.
### Itchy causes
- [Eczema](https://www.medicalnewstoday.com/articles/14417) can form red, itchy patches or small, liquid-filled bumps that eventually crust over.
- [Heat rash](https://www.medicalnewstoday.com/articles/181512) often causes redness, itchiness, or tingling.
- [Folliculitis](https://www.medicalnewstoday.com/articles/318551) is the infection of hair follicles, which can form tender, red, pus-filled bumps — typically on areas that are shaved or exposed to frequent irritation.
- [Psoriasis](https://www.medicalnewstoday.com/articles/52457) is an inflammatory skin condition in which excessive skin cell growth leads to thick plaques of skin that may be dry, scaly, and raised.
- [Contact dermatitis](https://www.medicalnewstoday.com/articles/318099) causes a bumpy rash that can be itchy and otherwise uncomfortable.
### Non-itchy causes
Bumps on the arms that are not itchy may point to acne. [Acne](https://www.medicalnewstoday.com/articles/107146) can cause [whiteheads](https://www.medicalnewstoday.com/articles/315104) or [blackheads](https://www.medicalnewstoday.com/articles/71615), and they [develop when](https://www.aad.org/public/diseases/acne/really-acne/symptoms) a person’s pores get clogged with:
- dead skin cells
- bacteria
- oil
## [Treatment]()
Doctors can recommend some ways to help relieve any itchiness and reduce the bumpiness of the skin.
### Exfoliation
The [AAD](https://www.aad.org/public/diseases/a-z/keratosis-pilaris-self-care) recommends taking the following steps to treat keratosis pilaris:
1. Gently [exfoliate the skin](https://www.medicalnewstoday.com/articles/exfoliate-face-naturally) to remove dead skin cells.
2. Apply a chemical exfoliator, also known as a keratolytic.
3. Use an oil-free moisturizer liberally.
They also provide the following advice for managing keratosis pilaris:
- make sure not to scrub the skin harshly
- use the keratolytic only as directed
- apply the moisturizer after using the keratolytic, after bathing, and whenever the skin feels dry
### Medications
Doctors [may prescribe](https://www.aad.org/public/diseases/a-z/keratosis-pilaris-treatment) or recommend an over-the-counter ointment or cream that contains one of the following ingredients:
- [lactic acid](https://www.medicalnewstoday.com/articles/lactic-acid-for-skin)
- [alpha hydroxyl acid](https://www.medicalnewstoday.com/articles/alpha-hydroxy-acid)
- [salicylic acid](https://www.medicalnewstoday.com/articles/salicylic-acid-for-acne)
- [retinoids](https://www.medicalnewstoday.com/articles/retinoids)
- [glycolic acid](https://www.medicalnewstoday.com/articles/glycolic-acid-for-skin)
- [urea](https://www.medicalnewstoday.com/articles/urea-in-skincare)
These medications help get rid of dead skin cells. A doctor may also recommend creams or lotions to help with moisturizing the skin.
One [study](https://onlinelibrary.wiley.com/doi/abs/10.1111/jocd.13387) suggests that a combination of natural glycolic acid and salicylic acid may be the best way to restore the skin’s texture. Indeed, 70–80% of participants who used the combination saw smoother skin with less oiliness and a more even texture.
If other treatments fail, a doctor may recommend [laser therapy](https://www.medicalnewstoday.com/articles/laser-skin-resurfacing) to reduce the bumps and any discoloration.
