Keratosis Pilaris: What It Is, What It Isn’t, and How I’m Treating It (Especially After Pregnancy)

If you’ve ever noticed tiny, rough bumps on your arms, thighs, or even cheeks that look like acne but don’t behave like it—you’re not alone. This skin condition is called keratosis pilaris, often shortened to KP, and it’s far more common than most people realize.


For me, keratosis pilaris first showed up around puberty, but it became noticeably worse during pregnancy, especially after I was pregnant with my son. Hormonal shifts changed my skin in ways I wasn’t expecting—and KP was one of the most frustrating ones.


This post is meant to be informative, gentle, and realistic. KP isn’t something you cure overnight. It’s something you manage, and understanding it makes all the difference.


What Is Keratosis Pilaris?

Keratosis pilaris is a harmless, non-contagious skin condition caused by a buildup of keratin, a protein that protects the skin.


When keratin builds up, it can plug hair follicles, leading to:


  • Small, rough bumps (often called “chicken skin”)

  • Dry or sandpaper-like texture

  • Redness or mild inflammation in some areas


KP commonly appears on:


  • Upper arms

  • Thighs

  • Buttocks

  • Cheeks


It affects children, teens, and adults, and often runs in families.


What Keratosis Pilaris Is Not


This is where a lot of confusion—and frustration—comes from.

Keratosis pilaris is not:


  • Acne

  • An infection

  • Caused by poor hygiene

  • Something you did wrong


And most importantly: it does not mean your skin is dirty.


Scrubbing harder, exfoliating daily, or trying to “dry it out” will not fix KP. In many cases, those approaches actually make it worse.


Why Does Keratosis Pilaris Happen?


There isn’t one single cause, but several factors contribute:


  • Genetics (KP often runs in families)

  • Dry skin or a weakened skin barrier

  • Hormonal changes (puberty, pregnancy, postpartum)

  • Cold or dry climates

  • Over-exfoliation


In my experience, pregnancy significantly worsened my KP. Hormonal shifts combined with increased dryness created the perfect environment for flare-ups, especially on my arms.


What Makes Keratosis Pilaris Worse


This is one of the most important things to understand, because many common skincare habits can backfire.


Things that made my KP worse:


  • Aggressive scrubbing

  • Exfoliating too often

  • Harsh soaps

  • Skipping moisturizer

  • Trying to “strip” the skin


KP-prone skin needs support, not punishment.


How I Exfoliate (Gently)


I exfoliate once a week only.


I use a gentle body scrub (such as a Dove body scrub) and avoid loofahs, dry brushing, or abrasive tools. The goal is to lightly remove surface buildup—not to scrub the skin raw.


Exfoliating more than once a week consistently made my KP more irritated and noticeable.


The Products I Use on My Keratosis Pilaris


My routine focuses on softening keratin, calming inflammation, and repairing the skin barrier.


Urea Lotion (Alternating Days)


Urea helps break down excess keratin while deeply hydrating the skin.

I use La Roche-Posay Lipikar Lait Urea 10% on KP-affected areas every other day.

It helps:


  • Smooth rough texture

  • Reduce keratin buildup

  • Improve overall skin softness


Salicylic Acid Lotion (Alternating Days)


On the days I don’t use urea, I apply CeraVe SA Lotion.

This lotion:


  • Gently exfoliates inside the follicle

  • Supports the skin barrier with ceramides

  • Helps reduce roughness without being overly harsh


Alternating these two products prevents over-exfoliation while still keeping KP under control.


When a Follicle Is Inflamed


Keratosis pilaris itself isn’t acne, but individual follicles can become inflamed from time to time.


When that happens, I use PanOxyl 4% Benzoyl Peroxide Wash only on the inflamed area.


A few important notes:


  • I don’t use it daily

  • I don’t apply it all over KP-prone skin

  • I always follow up with moisturizer


This helps calm inflammation without disrupting my entire routine.


What This Routine Has Taught Me


Keratosis pilaris isn’t about having “perfect skin.” It’s about consistency, patience, and being kind to your skin.


What helped me most:


  • Using fewer products

  • Gentle exfoliation

  • Regular hydration

  • Accepting that KP fluctuates


Pregnancy, postpartum life, stress, and seasonal changes all affect KP—and that’s completely normal.


Final Thoughts (Especially If You’re Pregnant or Postpartum)


If your keratosis pilaris worsened during pregnancy or after having children, you’re not alone—and you didn’t do anything wrong.


Hormones affect everything, including how our skin behaves.


You don’t need to scrub your skin into submission. A calm, intentional routine can make a meaningful difference over time.
