Today, I’d like to talk about a skin condition that many people tend to dismiss as “just dry skin,” but which can actually have a major impact on daily life.

That condition is “psoriasis.”

The skin we face in the mirror every morning is not just a simple bodily organ.

It is an area directly affected by the external environment, and it is an organ where cells are replaced on a regular cycle.

And clear, smooth skin goes beyond simple aesthetics—it can have a major impact on social confidence and overall quality of life.

But what if the skin becomes rough and white flakes of dead skin start to shed?

The entire skin may look very unclean, and it can become a major burden in how others see you.

There are many reasons why skin becomes rough. When exposed to a dry environment, various parts of the skin can visibly crack.

However, even if you have not been exposed to a particularly dry environment, if noticeable scaling begins to appear across the skin, you may want to suspect the chronic skin condition psoriasis.

From now on, at the plaque and guttate psoriasis treatment dermatology clinic, we will explain in an easy-to-understand way what psoriasis is and how it should be treated.

  • Today’s column outline -
  1. Symptoms that suggest psoriasis and the types by symptom
  2. What happens if psoriasis is left untreated and treatment methods
  3. Guidelines to help prevent recurrence after psoriasis treatment

Psoriasis: suspected symptoms and types by symptom

Psoriasis is a type of chronic skin disease, and it is characterized by red rashes and scaly, flaky skin.

However, when these symptoms appear, it is easy to dismiss them by thinking, “Maybe my skin is just dry these days.”

But if thick scales do not peel off over time, pile up layer by layer, or if the lesions spread even without scratching, you may want to suspect psoriasis.

Psoriasis shows different symptoms depending on the type.

First, plaque psoriasis is the most common type of psoriasis, and it is characterized by large red plaques covered with layers of silvery-white scales.

Guttate psoriasis can appear as numerous small eruptions all over the body, like tiny droplets splashing.

In addition, pustular psoriasis is a relatively aggressive type of psoriasis, and it is characterized by red, swollen skin with pus-filled pustules forming on top.

Fever and body aches, similar to having the flu, may also occur.

The last type of psoriasis we will discuss is scalp psoriasis, which can easily be confused with dandruff because the scalp becomes red and the scales thicken.

In addition, the symptoms can spread to the forehead, behind the ears, and the nape of the neck, so you should seek treatment as soon as possible.

Psoriasis: why early treatment is necessary and how it is treated

Early psoriasis begins as a single small red spot.

White, thick scales then build up on top of it, and it may sometimes itch or sting.

In some cases, even the fingernails become uneven and distorted, and the toenails begin to split and lift, and before long the symptoms can spread to the joints, causing aches and pains throughout the body.

And this can lead to psoriatic arthritis.

That is why, once psoriasis symptoms begin to appear, it is best to establish a treatment plan as quickly as possible.

Various treatment methods can be used for psoriasis, but the phototherapy explained today is a treatment that uses a wavelength of 311 nm, and it is characterized by its ability to help control excessive immune responses and inflammatory reactions.

Through this, the thick layers of scale can become thinner, and the red, thick lesions can gradually subside.

In addition, because phototherapy has a wide irradiation range, it can be broadly applied even to lesions that are spread over a large area.

Furthermore, since no separate surgical procedure is involved, a quick return to daily life may also be possible.

However, because this treatment uses specific light wavelengths, treatment may be difficult for patients with photosensitivity or cataracts, so please visit the clinic and receive detailed guidance.

Psoriasis: what to remember to help prevent recurrence

Psoriasis is essentially an autoimmune disease caused by an abnormal response of the immune system.

Because of this, even a slight problem in the immune system can make symptoms seem to improve, only for them to recur again before you know it.

Therefore, it is important to maintain a healthy immune system through consistent care.

First of all, emotional stress can directly stimulate the immune system, so it may be advisable to maintain regular routines that help stabilize both mind and body.

And since psoriasis fundamentally occurs when the stratum corneum becomes unstable, you should make it a habit to apply moisturizer every day.

Also, hot water and body washes with strong cleansing power can actually make the skin drier.

Therefore, when showering, it is better to use a mild cleanser and lukewarm water.

Finally, a moderate amount of sunlight can help relieve psoriasis, but excessive exposure to ultraviolet rays can irritate the skin and trigger symptom recurrence.

So please make sure to apply sunscreen carefully every time you go out.

Psoriasis is a signal that appears through the skin when the balance within our body is disrupted.

This is why simply covering the visible parts does not solve the problem.

Psoriasis can be a factor that shakes someone’s daily life, confidence, relationships with others, and even the rhythm of their entire life.

So if you are stressed by psoriasis symptoms, it is important to actively pursue treatment.

If any of you reading this are living with psoriasis, please do not ignore the signals your skin is sending, and visit a nearby clinic for a detailed examination.
