What Is Keratosis Pilaris? Why Scrubbing Makes Chicken Skin Worse

If you have small, rough bumps on your upper arms, thighs, or buttocks that never quite go away, no matter how much you scrub, there is a name for what you are experiencing. Keratosis pilaris is one of the most common skin conditions in the world. It affects roughly 40–50% of adults and up to 80% of teenagers.

The frustrating part is that most people treat it exactly the wrong way. Understanding what is actually happening inside the skin is the first step to managing it effectively.

Dr. Shachi Jain, Board-Certified Consultant Dermatologist, explains “Keratosis Pilaris is often mistaken for strawberry skin, but that is where most people go wrong. While they may look similar, they feel very different to the touch: KP is distinctly bumpy, whereas strawberry skin caused by clogged pores rather than keratin buildup is typically smooth. You can also differentiate the two based on their location on the body.

So, what exactly is KP? Short for Keratosis Pilaris, it is a condition where hair follicles become plugged with keratin. The name itself explains it: "Keratosis" refers to an overgrowth of keratin, and "pilaris" refers to the hair follicles. Because dry skin tends to trap more keratin, it leads to more frequent blockages.

Managing KP requires two simple steps: first, hydration to soften the keratin plugs, followed by gentle exfoliation to remove them. It sounds easy, but we often overcomplicate it by using harsh physical scrubs, which actually worsen the irritation

Did you know? KP is especially common among individuals who have the atopic triad: atopic dermatitis (eczema), asthma, and allergic rhinitis.”

What is keratosis pilaris and what causes it?

Keratosis pilaris is a condition where keratin, a protective protein naturally produced by the skin that builds up inside hair follicles instead of shedding normally. This trapped keratin creates small, rough plugs that push up against the skin surface, forming the characteristic bumps.

The condition is genetic and entirely harmless. There is no infection involved, and it is not contagious. It tends to worsen in dry conditions because dry skin sheds less efficiently, allowing keratin to accumulate faster. In the Indian context, it can also flare in both winter dryness and summer heat. For instance, sweat mixing with excess sebum can add to the blockage inside the follicle.

Most people with keratosis pilaris have it on the upper arms, thighs, and buttocks. Some experience it on the cheeks and it is “differentiated from acne by its texture and appearance and the fact that they are usually uniform in size” explains Dr. Shachi Jain. The bumps are often skin-coloured, though they can appear slightly red or brownish depending on your skin tone.

Why does scrubbing make keratosis pilaris worse?

Because the bumps feel rough and textured, the instinctive response is to scrub them away. Physical scrubbing, using a loofah, a rough scrub, or an exfoliating glove, can temporarily smooth the surface. But this approach almost always backfires over time.

Heavy physical exfoliation damages the skin barrier: the lipid layer that regulates moisture and keeps the skin's environment stable. When the barrier is compromised, the skin loses water more rapidly, becoming drier. Drier skin sheds less efficiently, which is exactly the condition that causes keratin to build up inside follicles in the first place. The bumps return, often worse than before.

This is one of the most common cycles seen with keratosis pilaris. People scrub, it briefly improves, then returns worse, so they scrub more. Breaking this cycle requires a fundamentally different approach.

What actually works for keratosis pilaris?

The correct approach addresses keratin buildup from the inside of the follicle rather than buffing the surface. Three elements work together:

• Chemical exfoliation: specifically BHA (salicylic acid) which is oil-soluble and penetrates the follicle to dissolve the keratin plug, or AHA (lactic acid) which works on the surface and also hydrates. Unlike physical scrubs, chemical exfoliants work at the source.
• Deep, consistent hydration: softening the skin helps keratin shed more normally. In-shower moisturisation is particularly effective because wet skin absorbs actives more deeply before the barrier closes.
• Barrier support: ingredients that mimic the skin's own lipids help restore the barrier that over-scrubbing has damaged. Squalane is especially well-suited to this because it is structurally similar to the skin's natural sebum and absorbs without heaviness — important in India's warmer months.

Hibiscus Monkey's Velvet Spray Squalene In-Shower Moisturiser is designed around this approach; applied on wet skin in the shower, it delivers squalane directly while pores are unclogged, combining the hydration and barrier support steps into one in-shower routine.

How long does it take for keratosis pilaris to improve?

Results from the correct routine typically take 8 weeks of consistency to become visible. It is extremely important to understand the importance of consistency and patience as patients usually leave treatment halfway because they are not guided properly and thus they think the treatment is not working. This is because you are addressing a cycle of skin cell turnover, not just surface texture. The skin needs time to shed old plugged follicles and produce new, unblocked ones.

Patience and consistency matter more than the intensity of any single product. Most dermatologists advise against switching products frequently before the 8-week mark.

Is keratosis pilaris permanent?

Keratosis pilaris is a chronic condition that has no permanent cure. However, it is highly manageable with the right routine and most people see significant improvement and can maintain smooth skin with consistent care. It often improves naturally with age, and many people find it becomes less prominent in their thirties and forties.

The key distinction is between treating it and managing it. Treating implies a one-time fix, which does not exist. Managing it with a consistent routine that combines gentle chemical exfoliation and barrier-supportive hydration delivers lasting results that feel like a fix.

Can diet affect keratosis pilaris?

The evidence base for diet and keratosis pilaris is limited. Some research suggests that vitamin A deficiency may contribute to keratosis pilaris, as vitamin A plays a role in keratin production regulation. Omega-3 fatty acids may support overall skin barrier function, though this is not KP-specific.

There is no strong clinical evidence that dairy, gluten, or other commonly cited foods directly cause or worsen keratosis pilaris in otherwise healthy adults. Topical treatment remains the primary evidence-based management approach.
