Keratosis pilaris is a common, harmless skin condition that no cream or scrub removes for good, but a gentle daily routine can make the bumps smoother and less noticeable. Often called “chicken skin,” it shows up as rough little bumps, mostly on the upper arms and thighs, and for many people it fades over the years. The routine dermatologists recommend is lukewarm water, light exfoliation and a urea or lactic acid moisturizer. Hard scrubbing, hot showers and picking tend to make it worse. See a pharmacist or dermatologist if the bumps itch, hurt or look inflamed.
What Keratosis Pilaris Is and Why It Happens
It is a plug of keratin sitting in a hair follicle. The NHS page on the condition says it happens when follicles become blocked with a buildup of keratin, “a substance found in skin, hair and nails.” Nobody knows exactly why, but it is thought to run in families. It is not infectious, so you cannot catch it or pass it on.
It is also very common. According to Cleveland Clinic, about 50% to 80% of teenagers and 40% of adults develop the bumps at some point, and people with eczema are more likely to have them. The NHS describes small, painless bumps in patches, usually on the arms, thighs or buttocks; the bumps are usually skin-colored but can also be red on white skin or darker on brown or black skin. Cleveland Clinic compares the texture to sandpaper and adds the face, back and chest.
Because the upper arms are the usual spot, KP shows most in sleeveless and off-shoulder clothes. The page for our pre-event package that treats the body as well as the face makes the same point from the other side: most people treat their face and forget everything below the jaw.
Keratosis Pilaris or Something Else?
KP bumps are rough, dry and painless; bumps that hurt, fill with pus or appear after shaving usually point to something else. Cleveland Clinic puts it simply: if pressing on a bump hurts, it is probably not KP. The closest look-alike is folliculitis, which DermNet’s guide to folliculitis defines as an inflamed hair follicle, giving “a tender red spot, often with a surface pustule.” DermNet counts acne as a type of folliculitis too.
| Bumps | What They Look Like | Usual Cause | What May Help | See a Dermatologist When |
|---|---|---|---|---|
| KP (“chicken skin”) | Tiny rough bumps on the upper arms, thighs or buttocks; painless, sometimes itchy | Keratin plugging the follicles; runs in families | Lukewarm water, gentle exfoliation, a urea or lactic acid moisturizer | It itches or looks inflamed, or home care has not helped after 4 to 6 weeks |
| Folliculitis | Tender red spots around hairs, often with a pus head | An inflamed follicle, from infection (often Staphylococcus aureus), blockage or irritation | Depends on the cause; a swab may be needed to find it | Spots are painful or pus-filled, or a deep, painful boil forms |
| “Strawberry legs” after shaving | Red, often very itchy bumps on shaved lower legs as hair regrows | Irritation from regrowing hairs (irritant folliculitis) | A break from hair removal, then a gentler method | The rash does not settle after you stop shaving, or turns painful |
| Acne on the body | Pimple-like spots, some red and tender with a pus head | A form of folliculitis | Depends on severity; some options are prescription only | Spots are deep or painful, or over-the-counter care has not helped |
| Eczema | Discolored, itchy patches that come and go | A common long-term skin condition; having it makes KP more likely | A diagnosis first, because the care differs | Patches are itchy, inflamed or broken |
“Strawberry legs” is an everyday name with more than one cause: Cleveland Clinic says KP bumps themselves “resemble the dotted skin of a strawberry,” while DermNet advises pausing hair removal for irritant folliculitis, then using a gentler method such as an electric razor. The two can overlap, since the AAD says shaving or waxing skin with KP can cause more bumps.
A Routine That Smooths the Bumps
The American Academy of Dermatology (AAD) recommends three steps: exfoliate gently, apply a chemical exfoliant, then moisturize. Its self-care guide for KP says this plan “may be all you need,” done every day until the skin looks clearer. Combined with the NHS self-care list, it looks like this:
- Keep showers short and lukewarm. The NHS advises cool or lukewarm water, never hot; the AAD suggests a bath or shower of 20 minutes or less in warm, not hot, water.
- Wash with something mild. Choose unperfumed products; the AAD notes that bar soap can dry your skin.
- Exfoliate gently. A loofah, rough washcloth or exfoliating mitt with light pressure is enough.
- Apply a keratolytic. The AAD names products with lactic acid, glycolic acid, salicylic acid, urea, an alpha hydroxy acid or a retinoid. Use it exactly as the label says, and stop for a few days if your skin turns dry or irritated.
- Moisturize within 5 minutes. Apply a thick, oil-free cream or ointment, ideally with urea or lactic acid, to damp skin after bathing, then again whenever skin feels dry, at least 2 or 3 times a day.
- Keep your hands off. The NHS says not to scratch, pick or rub the skin.
- Switch to maintenance. Once the skin looks clearer, the AAD describes a maintenance plan that often means treating it a few times a week.
Give it time: Cleveland Clinic says you should start seeing improvement within four to six weeks of following a plan. If the bumps reach your back, our guide to exfoliating the skin on your back covers tools and reach.
What Makes the Bumps Worse
Dry skin, hot water and friction make the bumps worse. The AAD says KP often flares when the skin becomes dry, and its tips and the NHS list name the habits to drop: hot or long showers, perfumed soaps and bathing products, scratching and picking, shaving or waxing over the bumps, and self-tanner, which makes them more obvious rather than hiding them. Using a keratolytic more often than directed can leave skin raw and irritated.
Hard scrubbing deserves its own warning, because it feels like the obvious answer to rough skin. The NHS says harsh scrubs “can make it worse,” and the AAD says scrubbing tends to irritate the skin and worsen the bumps. Cleveland Clinic explains why: irritated bumps become more discolored and noticeable, so a red, sore patch looks worse than the rough one you started with. It also warns that picking can lead to scarring or infection.
Humidity, Air Conditioning and Saigon Skin
Humid air tends to be kinder to KP skin than dry, air-conditioned rooms. The NHS says the skin may be better in summer and worse in winter, and Cleveland Clinic notes the bumps worsen when the air is drier. Our guide to skin in Saigon’s climate explains that air conditioning cools by removing moisture from the air, and that humidity falls in the December to April dry season.
So an air-conditioned office can still leave your arms dry, even in the wet season. The AAD suggests a humidifier when the air feels dry and moisturizing whenever skin feels dry, not only after a shower. Dead-cell buildup and dry indoor air also feature in our article on why skin starts to look dull.
When to See a Dermatologist
See a pharmacist or dermatologist if the bumps itch, look inflamed, hurt, or have not improved after four to six weeks of a steady routine. The NHS suggests a pharmacist when self-care is not helping, when the skin becomes itchy or inflamed, or when you are unsure whether you need a doctor. Get a check, too, for any bump that is painful when pressed, or a rash on a child you are unsure about.
Stronger options belong to a doctor. Cleveland Clinic mentions prescription-strength moisturizers, medicated vitamin A creams and laser treatment for discoloration. The NHS lists steroid creams and lasers but says they are not usually available on the NHS because they have not been proven to be effective. Ask a dermatologist whether any of them suits your skin.
Where a Spa Fits Before an Event
A spa does not treat KP, but before an event a professional exfoliation may help the skin look and feel smoother for a while; the home routine does the long-term work. If your skin is inflamed, itchy or broken, see a dermatologist instead of booking a scrub.
For a wedding, a photo shoot or an off-shoulder dress, our 120-minute pre-event package of full-body exfoliation and an intensive facial costs 700,000 ₫. Its page describes full-body skin renewal “to exfoliate and smooth” plus facial care adjusted to your skin, and makes no claim about KP. Mention prescription skincare (retinoids especially), sensitivities, recent sunburn or pregnancy so the steps can be adjusted. The page also says daily sunscreen afterward matters more than usual.
For the body alone, the 60-minute full body scrub with a mineral-rich exfoliant costs 400,000 ₫. Its page lists bumpy texture along the legs and upper arms among what it helps with, and gives firmer attention to elbows, knees and heels. Since the AAD warns against hard scrubbing, tell the therapist you have KP: the page says pressure and product are adjusted, or areas avoided, for skin conditions, eczema or open cuts. It suggests a scrub every three to four weeks and no sun without sunscreen for the first few days, because newly exfoliated skin burns more easily.
The scrub is one of four treatments on our menu of body and skin treatments in District 1. None of them treats KP or any other skin condition.
Chicken Skin, in Short
Keratosis pilaris is a harmless keratin plug in the hair follicles, and for many people it fades over time. No routine makes it disappear for good, but short lukewarm showers, gentle exfoliation, a keratolytic used as directed and a thick urea or lactic acid moisturizer may start to smooth the bumps within four to six weeks. Skip hard scrubs, hot water and picking, and see a pharmacist or dermatologist if the skin itches, hurts, looks inflamed or does not improve.

Frequently Asked Questions About Keratosis Pilaris
Does Keratosis Pilaris Go Away on Its Own?
Often, but slowly. The NHS says most people have it for years and that it may eventually clear up by itself. Cleveland Clinic says most cases start to clear around the mid-20s and usually disappear by about age 30. Until then, lukewarm water, gentle exfoliation and a urea or lactic acid moisturizer keep the bumps less noticeable.
Can You Get Keratosis Pilaris on Your Face?
Yes. The AAD says children may have the bumps on their cheeks, and Cleveland Clinic lists the cheeks, neck and the area under the eyes among the places it can appear. Ask a pharmacist or dermatologist before treating bumps on your face, and use any product only as directed: the AAD warns that overusing a keratolytic can leave skin raw and irritated.
Is Chicken Skin Contagious?
No. The NHS says the condition is not infectious, so you cannot catch it or spread it to anyone else. It comes from keratin blocking your own hair follicles and is thought to run in families. Bumps that are painful or filled with pus are a different matter: folliculitis can come from an infection, so ask a doctor.
Which Cream Ingredients Help With Chicken Skin?
Look for urea or lactic acid. The AAD recommends a thick, oil-free cream or an ointment containing one of them, applied to damp skin within 5 minutes of bathing, rather than a thin lotion. For chemical exfoliation it names lactic, glycolic and salicylic acid, urea, alpha hydroxy acids and retinoids. Ask a dermatologist about anything prescription-strength.
Is It Safe to Pop or Squeeze the Bumps?
No. The NHS says not to scratch, pick or rub the skin, and Cleveland Clinic warns that picking or trying to pop the bumps can lead to scarring or infection. Irritated bumps also turn more discolored and noticeable, Cleveland Clinic adds. Gentle exfoliation and a moisturizer are the safer route.
How Long Before a KP Routine Starts Working?
Usually four to six weeks. Cleveland Clinic says you should start seeing improvement within that time if you follow your treatment plan, and to contact a healthcare provider if you do not. After that, the AAD describes a maintenance plan, often treating the skin a few times a week, to keep the bumps under control.
Can a Spa Body Scrub Remove Chicken Skin?
No. A spa scrub removes dead cells from the surface and may leave skin feeling smoother for a while, but the AAD says the condition needs an ongoing maintenance plan at home. Tell your therapist you have KP so the pressure can be adjusted, and see a dermatologist rather than booking a scrub if the skin is inflamed, itchy or broken.
