Board-Certified Dermatology Care in Busan

Skin symptoms can have many different causes, even when they appear similar. OZ Dermatology focuses on physician-led diagnosis before recommending medication, laser treatment, injections, surgery or another dermatologic procedure.

The clinic treats both common and complex skin conditions. Treatment is personalized according to the diagnosis, skin type, medical history, symptom severity and response to previous care.

Medical Dermatology

OZ Dermatology provides medical evaluation and treatment for symptoms affecting the skin, hair and nails.

Patients may visit the clinic for:

• Persistent rashes
• Itching and inflammation
• Acne and recurring breakouts
• Eczema and dermatitis
• Psoriasis
• Rosacea
• Fungal infections
• Nail disorders
• Warts
• Hair and scalp concerns
• Suspicious moles or skin growths
• Scars and keloids
• Vascular skin lesions

An examination is necessary because treatment varies considerably between conditions with similar symptoms.

Acne Treatment

Acne treatment should address the type and cause of the breakout rather than only the visible lesions. OZ Dermatology assesses inflammatory acne, clogged pores, excess sebum, cystic lesions and post-acne changes before recommending treatment.

A personalized acne plan may include:

• Prescription medication
• Topical treatment
• Acne extraction
• Inflammation-reducing injections
• Medical skincare
• Energy-based procedures
• Scar-prevention guidance

Persistent or recurrent acne may require ongoing management rather than a single treatment.

Acne Scar Treatment

Acne scars differ in depth, shape and tissue structure. Common types include rolling, boxcar, ice-pick and raised scars. Many patients also have enlarged pores, redness or pigmentation after acne.

Treatment may involve one procedure or a combination selected according to the scar type. The goals may include improving texture, softening visible depressions and making the overall complexion appear more even.

Deeper scars generally require multiple treatment sessions, and complete scar removal cannot be guaranteed.

Eczema and Dermatitis Treatment

Eczema and dermatitis may cause itching, redness, dryness, scaling, cracking or recurring inflammation. Possible triggers include irritation, allergies, environmental exposure and changes in the skin barrier.

Treatment may include prescription medication, moisturization, trigger management and instructions for protecting the skin barrier. Recurrent symptoms should be evaluated rather than repeatedly treated with unverified products.

Psoriasis Treatment

Psoriasis is a chronic inflammatory condition that may cause thick, scaly or red skin lesions. It can affect the scalp, elbows, knees, hands, feet, nails and other areas.

Management depends on the location, severity and extent of the condition. Treatment may include topical medication, systemic treatment or light-based therapy when appropriate.

Rosacea and Facial Redness

Rosacea can cause persistent facial redness, flushing, visible blood vessels and acne-like bumps. Heat, alcohol, spicy food, stress and sun exposure may worsen symptoms in some patients.

Treatment is selected according to the rosacea subtype and may include medication, skincare guidance or vascular laser treatment. Patients with sensitive skin should avoid aggressive procedures without a dermatologic evaluation.

Vascular Lesions and Malformations

Dr. Oh has particular clinical and academic interest in vascular tumors and malformations. Vascular conditions can vary from superficial visible vessels to more complex lesions requiring careful assessment.

Evaluation may be considered for:

• Facial redness
• Visible capillaries
• Cherry angiomas
• Hemangiomas
• Port-wine stains
• Other vascular growths or malformations

Treatment suitability depends on the lesion type, depth, location and medical history. Some conditions may require imaging, biopsy or referral for multidisciplinary care.

Pigmentation Treatment

Dark spots can result from sun exposure, inflammation, hormonal changes, aging or other medical causes. Melasma, freckles, lentigines and post-inflammatory hyperpigmentation do not necessarily respond to the same treatment.

OZ Dermatology evaluates the pattern and suspected pigment depth before recommending medication, skincare, laser treatment or a combined plan.

Daily sun protection is important because ultraviolet exposure can contribute to recurrence and uneven pigmentation.

Scar and Keloid Treatment

Scars may become raised, red, thick, painful, itchy or wider than the original wound. Keloids can extend beyond the boundaries of the initial injury and may continue to grow.

Treatment options may include:

• Prescription treatment
• Intralesional injections
• Laser procedures
• Scar revision
• Surgical removal
• Combination therapy

Keloids have a risk of recurrence, so treatment planning and follow-up are particularly important.

Dermatologic Surgery

Dermatologic surgery may be used to diagnose or treat selected moles, cysts, benign growths, scars and suspicious skin lesions.

Depending on the condition, the process may include:

1. Dermatologic examination
2. Dermoscopy or other diagnostic assessment
3. Skin biopsy when medically indicated
4. Pathology testing
5. Excision or another appropriate procedure
6. Wound and scar management

The treatment method is selected according to the diagnosis, lesion location and need to preserve healthy tissue.

Mole and Skin-Growth Evaluation

Most moles and skin growths are benign, but a lesion should be examined when it changes in color, shape or size or begins bleeding, itching or forming a persistent wound.

A dermatologist can determine whether cosmetic removal is appropriate or whether a biopsy and pathology examination should be performed first.

Wart Treatment

Warts are caused by human papillomavirus and can occur on the hands, feet, face and other areas. They may spread to surrounding skin or other people.

Treatment depends on the location, size, number and depth of the warts. Multiple sessions may be required, particularly for plantar or recurrent warts.

Fungal Skin and Nail Treatment

Fungal infections can affect the body, feet, scalp and nails. Nail fungus may cause thickening, discoloration, brittleness or separation of the nail.

Because trauma and inflammatory conditions can resemble a fungal infection, diagnostic confirmation may be recommended. Treatment can include topical medication, oral medication or laser treatment for suitable patients.

PinPointe Nail Fungus Laser

OZ Dermatology provides laser treatment options for selected cases of nail fungus. PinPointe laser treatment delivers energy through the nail to target the affected area.

Suitability depends on the diagnosis, extent of infection and the patient’s medical history. Because healthy nails grow slowly, visible improvement may take several months even after successful treatment.

Hair and Scalp Concerns

Hair loss can be related to genetics, hormones, inflammation, stress, medication, nutritional factors or an underlying medical condition.

Dermatologic evaluation may be appropriate for:

• Male or female pattern hair loss
• Sudden excessive shedding
• Patchy hair loss
• Inflamed or itchy scalp
• Scaling and dandruff
• Hair breakage
• Scarring hair loss

Treatment is selected after determining the likely cause rather than applying the same hair-loss program to every patient.

Skin Ultrasound Evaluation

Skin ultrasound may be used to evaluate selected lesions or structures beneath the skin. It can provide information about depth, size and surrounding tissue that may not be visible through surface examination alone.

The dermatologist determines whether ultrasound is useful based on the suspected diagnosis and planned treatment.

Laser and Energy-Based Dermatology

Energy-based treatments may be used for selected vascular lesions, pigmentation, acne, scars, skin texture and age-related concerns.

The most appropriate device and settings depend on:

• The medical diagnosis
• Skin color and sensitivity
• Lesion depth
• Previous treatments
• Risk of pigmentation
• Acceptable downtime

A device should be selected based on the patient’s condition rather than popularity alone.

Skin-Regeneration and Anti-Aging Treatment

OZ Dermatology also evaluates patients concerned about skin texture, elasticity, fine lines and age-related changes. Depending on the skin condition, the dermatologist may recommend laser treatment, energy-based procedures, collagen-stimulating treatment or other regenerative approaches.

The objective is to create an evidence-informed plan while considering natural facial balance, skin health and recovery time.
