Oozing, flaking, red spots,
what are they called in medical terms?

A skin lesion is not a specific disease name, but a term referring to observed changes such as redness, blisters, scaling, or swelling.

Erythema is a term describing a state where the skin has turned red, not a single disease name. It is necessary to check if the redness fades when pressed and if heat, pain, or scaling are present.

A papule refers to a small, raised skin lesion. Unlike pustules containing pus or vesicles containing clear fluid, they often feel firm beneath the surface.

In dermatology, a plaque-like lesion is a wide, raised lesion with a visible border. Psoriatic plaques, where scales accumulate on a red base, are representative, but this shape itself does not necessarily mean it is psoriasis.

A vesicle refers to a small blister. Causes vary, such as pompholyx (dyshidrotic eczema) occurring deep on the sides of fingers, contact dermatitis, or infections; therefore, the location, pain, itching, and whether they appear in clusters are examined.

A pustule is a small lesion filled with yellow or white contents. They are common in folliculitis, but not all pustules have the same cause.

A wheal is a swollen area similar to a mosquito bite; a key clue is that the same lesion fades within a relatively short period of time.

Scaling refers to dead skin that appears white, silvery, or yellowish on the skin surface. We examine the color, thickness, degree of adherence, and the boundaries of the lesion.

Exudate is a change often described as "oozing." While it can occur from eczema itself, if it is accompanied by pus, pain, or fever, the possibility of infection must be evaluated separately.

A crust refers to a scab dried on the skin surface. Rather than just color and thickness, we examine what has dried and whether there is pain, heat, or spreading.

A fissure is a state where the skin is cracked, creating a gap, which can cause pain and bleeding on the hands, feet, or folded areas.

In dermatology, an excoriation refers to a linear wound caused by scratching due to itching. It serves as a clue to distinguish between the original lesion and changes caused by scratching.

Lichenification is a condition where the skin becomes thick and rough due to a cycle of chronic itching and scratching. A cycle can occur where the skin is itchy because it is thick, and it continues to thicken because of the itching.

Comedones are lesions where the follicle opening is blocked; open comedones may appear black, and closed comedones may appear white or as skin-colored bumps.

Telangiectasia is a change where thin red lines are persistently visible on the cheeks, nose, etc. It may appear alongside temporary flushing, but they do not mean the same thing.

Distribution describes not only "where it appeared" but also whether both sides are similar, if it is in a skin fold, or if it follows areas exposed to sunlight, cosmetics, or clothing.

An exacerbation period is when itching, redness, or oozing occurs, or when the area of the lesion increases more than usual. This does not always mean that a new disease has developed.

Pruritus means itching. It can include both itching with distinct skin lesions and itching with few visible changes.

The itch-scratch cycle does not indicate a lack of willpower. It is a physiological repetition where itching triggers scratching, and skin damage in turn increases the itching.

Recurrence may be the reappearance of the same disease, but it could also be a new disease that looks similar. It is necessary to check if the location, shape, and triggering situations are the same.

A chronic course does not mean it cannot be treated, but refers to a state that continues or repeats beyond a certain period. The criteria for the duration may vary depending on the disease.

Skin dryness may manifest as tightness after washing, a rough texture, flaky skin, and itching. It is influenced not only by a simple lack of moisture but also by dermatitis, age, and environmental factors.

Photosensitivity is a reaction characterized by redness, itching, or blisters, primarily in areas exposed to sunlight. Since medications, cosmetics, or other medical conditions may be involved, we evaluate exposure time and current medications together.

Skin heat sensation is the feeling that the "skin is burning or flushing." We distinguish between actual fever, inflammatory heat, flushing, and neurogenic sensations.

The skin barrier is not a single visible layer, but refers to the function of the outer skin layer to hold moisture and block irritants. If the barrier is weakened, the skin can easily become dry, sting, or crack.

Chronic urticaria refers to cases where wheals or angioedema recur for more than 6 weeks. Even if they do not occur daily, we record the triggers on the days they appear, the duration, and the response to medications.

Inducible urticaria refers to cases where wheals appear after relatively constant stimuli, such as exercise, increase in body temperature, cold air or water, pressure, and friction. The type of stimulus and the reaction time are checked together.

Skin fungal infections are commonly called athlete's foot or tinea. A diagnosis is not made based on the round shape alone; the keratinization of the edges, the affected area, and fungal tests are checked together.

Secondary infection refers to cases where an infection is added on top of eczema or scratched wounds. Pain, heat sensation, pus, yellow scabs, and rapid spread can be clues.

Angioedema is a condition where the lips, area around the eyes, hands, or feet swell deeply, either along with urticaria or separately. Swelling of the tongue and throat, or difficulty breathing, can be an emergency.

Dermatographism is a reaction where the skin becomes red and swells along the pressure of fingernails or clothing. Rather than simply describing the skin as sensitive, the onset time and itching are examined together.

The Koebner phenomenon refers to the development of lesions from an existing condition, such as psoriasis, along the site of a skin injury. It does not refer to all scratch marks or scars.

Atopic predisposition refers to a tendency to be prone to allergic diseases, but it does not mean that a single specific food is the cause or that it will never be cured throughout one's life.

Contact allergens are substances such as fragrances, metals, and preservatives that can cause an allergic reaction when they touch the skin. This is not the same as an irritating substance.

Allergens are substances that trigger allergic reactions, such as food, medication, pollen, mites, or contact materials. The mere fact of exposure does not confirm it as the cause of the symptoms.

Sensitization means that an immune response to a specific substance can be identified during a test. This is not always the same as a clinical allergy, where symptoms actually occur upon ingestion or contact.

Irritant contact dermatitis can occur due to repeated housework, cleansers, friction, and chemicals, even in the absence of an allergy.

Allergic contact dermatitis is a condition where itching, redness, or blisters appear on the area that touched a substance after becoming sensitized to it. The reaction may not appear immediately and can be delayed.

Urticaria is a condition characterized by the appearance of itchy, swollen wheals. A key clue is whether the same lesion fades within a relatively short period of time.

If you experience severe itching during pregnancy, especially on the palms of your hands and soles of your feet, with few visible rashes, it may be necessary to check for causes such as intrahepatic cholestasis of pregnancy.

A patch test is an examination where various substances are applied to the back, and skin reactions are monitored over several days. It serves a different purpose than the skin prick test, which looks for immediate allergies.

A fungal test is an examination that confirms a mold infection by scraping keratin to view under a microscope or by culturing it if necessary.

A skin biopsy is a procedure where a sample of skin is collected to identify diseases that are difficult to distinguish by visual appearance and progression alone.

Topical treatment is a therapy using medication applied directly to the skin. The method of use varies depending on the ingredients, potency, application area, amount, and duration.

Topical steroids are representative topical agents used to reduce redness and itching in inflammatory skin diseases such as eczema and atopic dermatitis. They must be used according to the prescription regarding potency, area, and duration.

Topical calcineurin inhibitors are topical medications used for conditions such as atopic dermatitis, and they control inflammation differently than steroids.

Antihistamines are primarily used to reduce hives (wheals) and itching. Depending on the type, the degree of drowsiness and the dosage instructions vary.

Phototherapy is a treatment that systematically uses medical-grade UV light for certain skin conditions such as psoriasis and atopic dermatitis. It is different from getting a lot of sunlight or tanning.

Skin atrophy refers to a state where the skin thickness is reduced, making it thin and weak. There can be various causes, such as the inappropriate long-term use of strong topical steroids.

Combined care for skin diseases is a process of determining the order of currently necessary treatments by transparently sharing dermatology diagnoses, topical agents, tests, and Korean medicine evaluations.

Pattern identification is not about giving a different name to a disease. It is the process of determining which treatment to prioritize by observing accompanying changes, such as oozing, heat, dryness, and lichenification, as well as sleep, digestion, and fatigue.

In skin care, Damp-Heat is used to describe patterns where there is significant oozing, redness, and prominent heat and itching. It does not refer to a specific bacterium or test value.

Blood-Heat is a Korean medicine term used to classify patterns where the skin is red with strong heat or accompanied by hemorrhagic changes. It does not refer to blood temperature or abnormalities in blood tests.

In skin care, a Wind pattern refers to the nature of changes where rashes develop quickly, migrate, and itch, rather than referring to wind as a single external cause.

A Dryness-Prominent Pattern refers to a state where the skin is dry, showing keratinization and cracking, accompanied by chronic itching. It does not simply mean that you have drunk too little water.

Yin-Blood Deficiency does not mean the same thing as a general test result indicating a lack of blood. It is a Korean medicine expression that interprets various findings together, such as skin dryness, chronic itching, sleep quality, and energy levels.

In skin care, examining the constitution and recurrence patterns does not mean attributing all causes to one's constitution. It means verifying whether the timing of symptom aggravation actually aligns with the body's overall condition to reflect this in the herbal medicine prescription.
