Persistent flushing in the center of the face and burning sensation, comedones, and oily scales around the sides of the nose and eyebrows are characteristic of different conditions. In some cases, both conditions may coexist.

Points to check in the photos first

Even if they look similar, the dead skin, blisters, and borders may differ

We have provided both typical appearances and examples that look slightly different. Do not decide based on a single similar photo; compare how long symptoms like dead skin, wheals, comedones, or oozing have persisted in the same area.

Persistent erythema and burning sensations in the center of the face, along with fine blood vessels, are used to distinguish this from acne, which is centered around comedones. Only the skin surface is shown in close-up, excluding the eyes.

Rosacea can also look like acne if breakouts are mixed in. Check for a base of persistent flushing, burning sensations, and fine blood vessels, and confirm that no comedones are present.

Comedones are important clues for distinguishing acne from rosacea or seborrheic dermatitis. Do not just compare red pimples; check if clogged pores are also visible.

Points to check	Rosacea	Acne	Seborrheic Dermatitis
Core Appearance	Persistent flushing · burning sensation · visible capillaries	Comedones and inflammatory lesions	Oily or fine scales over redness
Primary Location	Cheeks, nose, center of face	Face, chest, back	Scalp, eyebrows, sides of nose, around ears
Aggravating factors	Heat, alcohol, spicy food, UV rays	Products, friction, hormonal changes	Oil-prone areas, seasonal changes
Differential points	Usually no comedones	Presence of comedones is a key clue	Flaking and scalp symptoms

Ask whether flushing or breakouts occurred first

In rosacea, lesions that look like acne can develop on a background of skin that easily flushes and feels hot. If comedones are present and lesions appear outside the face, it points more toward acne.

Flaking on the sides of the nose and eyebrows suggests seborrheic dermatitis

Seborrheic dermatitis can present as redness and flaking on the eyebrows, between the eyebrows, sides of the nose, and around the ears, along with scalp dandruff. In some cases, rosacea and seborrheic dermatitis coexist, meaning a single treatment may not be sufficient.

Do not add more products as your skin becomes more sensitive

Layering multiple cleansers, exfoliants, or acidic ingredients can blur the line between the original condition and an irritation response. Simplify your routine by removing recently added products, maintain gentle cleansing and UV protection, and confirm the diagnosis.

Please note any other symptoms observed when your face becomes red

Please note whether the redness or the breakouts appeared first, if blackheads or whiteheads were visible, and if there was flaking around the nose or eyebrows. Also, let us know about any changes after exposure to heat, alcohol, or spicy foods.

Seborrheic dermatitis is characterized by thin, greasy scales in areas with high sebum production, such as the scalp, eyebrows, and sides of the nose. We compare the surface with scalp psoriasis, which forms thick plaques.

For facial redness, we examine comedones, flaking, heat stimulation, and distribution together.

Medical Evaluation GuideWhat should I record when symptoms improve after applying ointment but then reappear?Rather than simply noting that symptoms have reappeared, please record which area became itchy again and after how many days, the name and frequency of the ointment used, and any new changes such as oozing, pain, or a feeling of heat. It is important to consult with your prescribing medical provider before suddenly stopping or changing a prescribed ointment on your own.Medical Evaluation GuideWhen your skin changes after using new cosmetics, shampoo, or detergentsRather than attributing the cause to a single new cosmetic product, please record the affected areas, the date you started using it, whether the product was rinsed off or left on the skin, and any substances you come into contact with through your occupation or hobbies. Sensitive areas such as the eye area and face can also be affected indirectly through substances on your hands or in the air.

Skin terms used in this differential guide

TelangiectasiaTelangiectasia refers to a change where fine red lines are persistently visible on the cheeks, nose, etc. It may appear alongside temporary flushing, but it does not mean the same thing.PapuleA papule refers to a small, raised skin lesion. Unlike pustules containing pus or vesicles containing clear fluid, papules often feel firm beneath the surface.Skin heat sensationSkin heat sensation is the feeling that the skin is "burning or flushing." We distinguish between actual fever, inflammatory heat, flushing, and neurogenic sensations.ScalingScaling (squama) refers to the dead skin cells that peel off the skin surface in white, silvery, or yellowish colors. We examine the color, thickness, degree of adherence, and the borders of the lesion together.ErythemaErythema is a term used to describe the state of the skin becoming red; it is not the name of a single disease. It is necessary to observe whether the redness fades when pressed and if it is accompanied by heat, pain, or scaling.

When herbal medicine treatment is the primary focus

We set the goals for herbal medicine treatment based on your previous treatments and when symptoms recurred

Redness and papules on the face and scalp can recur not only due to external exposure and local inflammation, but also in conjunction with heat sensations, stress, and sleep patterns. Based on differential diagnosis and previous treatments, Korean herbal medicine treatment focusing on managing the conditions that cause recurrence may be central.

Before the consultation

We ask where it appeared and when it worsened again

We examine the duration of the flushing, the presence of capillaries, papules, pustules, and scales, as well as eye symptoms and reactions related to digestion, sleep, and tension.

During treatment

We check if not only the itching, but also sleep and daily life are improving

We check how long the redness lasts, the number of new papules, the burning sensation, and the burden felt during face-to-face activities.

Treatment sequence

We set the goals for herbal medicine treatment by identifying the problems that need to be resolved first

If there are causes that require immediate priority, such as infection or rapid worsening, those treatments come first. Subsequently, for herbal medicine treatment, we determine the primary goal of recovery by examining current discomfort, recurring patterns, sleep, digestion, and fatigue, and coordinate the sequence with necessary dermatological treatments.

While reducing aggravating factors through lifestyle management, herbal medicine treatment determines the initial target by analyzing the pattern of lesions, sleep, digestion, and fatigue through pattern identification (Byeonjeung). Necessary skin treatments are continued in accordance with the progress.
