Following our wonderful time meeting so many of you at the Beauty Trade Special in Utrecht, we noticed something. Everyone came to our stand with a different name for their skin struggle, whether it was eczema, melasma or hormonal acne, yet our conversations kept circling the same idea: skin that feels like it is reacting faster than you can keep up with.
So let’s look at the actual science behind psoriasis. By understanding what makes this condition unique, we can see exactly how to guide your skin back to a place of comfort, keeping things simple, human and grounded in real biology.
Psoriasis shows up as raised, red or pink patches topped with silvery scales, known as plaques. They tend to appear on the elbows, knees, scalp and lower back, though they can settle almost anywhere. The patches can feel tight, intensely itchy and prone to painful cracking (Cleveland Clinic, 2024; NHS).
Here is the most important thing to know: psoriasis is not a hygiene problem, and it is not something you have caused. It is an autoimmune condition, driven from the inside by the immune system (American Academy of Dermatology). That single fact is what makes a calmer, more patient approach the effective one rather than the soft option.
To understand psoriasis, it helps to look at the rhythm of how skin grows. In a typical skin cycle, a healthy cell is born deep in the lower layers, takes roughly 28 days to mature, rises to the surface and naturally sheds away (Cosmetics, MDPI, 2017).
With psoriasis, the immune system sends a faulty, hyperactive signal that speeds this timeline up to roughly 3 to 5 days (Merck Manual, Professional Edition). Because the old cells have not had time to flake away, these new, rapidly produced cells crash to the surface and pile up on top of one another. That build-up is what creates the characteristic plaques. And because the skin is multiplying at such a frantic pace, it becomes tight, itchy and prone to cracking.
When faced with rough, scaly patches, a very natural human instinct is to try to scrub them away with harsh physical exfoliants or an intense body mitt. But psoriasis hates friction.
Triggering friction can set off a biological reaction known as the Koebner phenomenon, where the skin views the scrubbing as an injury and responds by producing even more cells, so new plaques form in the exact area you just scrubbed. It is well documented: around a quarter to a third of people with psoriasis experience it, and physical trauma and mechanical stress such as scratching are recognised triggers (Sagi & Trau, Koebner phenomenon review, Bioscience Reports / PMC, 2019; DermNet NZ).
This is the heart of the Junita® Lab philosophy: build before you brighten. We do not believe in fighting the skin or trying to scrub the scales away by force. A calm, well-supported barrier is the foundation that lets everything else settle, without tipping the skin into the panic response that makes plaques worse.
Our core philosophy is biomimicry: we use gentle ingredients your skin already recognises as its own, to soothe the rush from the outside. Here is how the pieces fit together, and where each one lives in the range.
Instead of rough scrubs that can trigger the Koebner phenomenon, we look to urea at balanced, gentle levels. Urea is part of your skin’s own natural moisturising factor, which is why it sits so comfortably on reactive skin. It is a humectant that draws in and holds water, and at the levels used in skincare it acts as a mild keratolytic, helping to soften the cellular “glue” holding dead scales together so they can lift away gradually, without friction or irritation (Celleno et al., Urea in Dermatology, Dermatology & Therapy, 2021). It is a key ingredient in our ACB Hydrobalance™ Toner.
Ectoin is an “extremolyte”, a molecule certain microbes use to survive harsh environments. On skin it forms a protective hydration shell around cells, helping to stabilise the skin’s structure and calm its response to environmental and temperature stress, the kind of flushing and heat that can aggravate reactive skin (Bilstein et al., topical ectoine systematic review, PMC, 2022). It is in our Tetrapeptic™ Day Cream.
Because psoriasis cells rush to the surface so quickly, they struggle to form a properly sealed outer wall, which leads to significant moisture loss. We use plant-based oils chosen to echo your skin’s own lipid profile, working alongside niacinamide (vitamin B3) to help patch the gaps, hold in hydration and support the look of redness (Marques et al., niacinamide review, PMC, 2024). You will find this pairing woven through our Tetrapeptic™ Day Cream and Nocturnaid™ night cream.
While our specific formulations remain the private heart of Junita® Lab, our goal is to empower you with the honest knowledge you need to care for your skin safely.
In a world that constantly promises overnight miracles, we would rather be completely honest about how skin actually settles. Think of a gentle routine as a steady re-education for your cells. It takes around 3 to 4 months of consistent, loving care for skin to begin showing real change and to ease away from its frantic pace, because skin renews on its own rhythm and cannot be rushed (Epidermal turnover kinetics, PubMed).
Committing to that gentle path for 6 to 12 months is how you deeply rebuild the protective outer wall. Patience here is not a consolation prize. It is the strategy.

Skincare cannot cure an autoimmune response, but it can be a powerful daily ally to take the discomfort out of your day. Please speak to a professional if:
A useful way to think of it: medical professionals look after the internal triggers, while Junita® Lab provides the daily external barrier shield that keeps your skin calm and comfortable in between.
If your skin has been worked hard, or if scrubbing has been a habit, the most helpful first move is usually to do less, not more. As a starting point, try this for four weeks:
Junita® Lab exists on a simple idea: the most powerful thing you can do for difficult skin is help it heal itself. We are not interested in promising overnight transformations. We are interested in formulas that work with your skin’s biology, use evidence-backed ingredients, and stay gentle enough that your skin still feels good with them months down the line. Stepping away from the frustration of quick fixes, and choosing a steady, gentle route, is always the true winner.
“It has taken me eight years of hard work, research and true dedication to get where I am today. I’ve had my own share of setbacks along the way, moments where my skin reacted unexpectedly or things didn’t go as planned.
I can honestly tell you that my skin will never be ‘flawless’ or ‘perfect’, because skin is a living, changing organ that breathes and reacts to life. But I can proudly say that when I look in the mirror now, I see skin that is healthy, beautiful and deeply cared for. My greatest joy is helping you find that same feeling of contentment when you look at your own reflection.”

Psoriasis is an autoimmune condition. The immune system sends a faulty, overactive signal that speeds up skin-cell production, so cells pile up at the surface as plaques. It is not caused by poor hygiene and it is not contagious. Triggers such as stress, infection, skin injury and certain medicines can set off or worsen a flare.
In healthy skin a cell takes around 28 days to rise to the surface and shed. In psoriasis that drops to roughly 3 to 5 days, so new cells reach the surface before the old ones have flaked away. They crash together and pile up, forming the raised plaques with their silvery scale.
Not with harsh scrubs or mitts. Friction can trigger the Koebner phenomenon, where the skin treats the scrubbing as injury and forms new plaques in that spot. A far gentler route is a softening, water-loving ingredient like urea, which helps lift scale without abrasion.
It is when new psoriasis plaques appear at sites of skin trauma, such as scratching, friction, a cut or even a scrape. Research suggests around a quarter to a third of people with psoriasis experience it. It is the main reason we steer away from aggressive scrubbing.
Urea is part of the skin’s own natural moisturising factor. It draws in and holds water, and at skincare levels it gently softens the build-up of dead, scaly cells so they lift away without friction. That makes it a kinder alternative to physical scrubbing for rough, flaky patches.
No. Psoriasis is an internal autoimmune condition, and skincare cannot cure an autoimmune response. What a gentle, barrier-led routine can do is support comfort, reduce the feeling of tightness and itch, and care for the skin’s outer wall between flares. Medical care addresses the internal side.
Be patient and honest with yourself. It takes roughly 3 to 4 months of a steady, gentle routine for skin to show real change, because skin renews on its own rhythm. Committing for 6 to 12 months is how you deeply rebuild the protective barrier.
Look for barrier-supportive, low-irritation ingredients: urea to soften scale, ectoin to calm, niacinamide for the barrier, and skin-identical oils to hold in moisture. Avoid harsh physical exfoliants, very hot water and anything that leaves skin feeling tight or stripped.
No. Psoriasis cannot be passed from person to person. It is an immune-driven condition that happens inside your own body, not an infection. You cannot catch it by touch, and you cannot give it to anyone else.
Yes. Junita products are cosmetics designed to support healthy, barrier-led skin, well-suited to a calm, gentle routine. We would start with the ACB Hydrobalance™ Toner, Tetrapeptic™ Day Cream and Nocturnaid™. They are not medical treatments, so please keep working with your GP or dermatologist on the internal side.
