Why Choose YSBB?

Board-Certified Expertise

YSBB was founded by board-certified dermatologists trained at Yonsei University College of Medicine. Our physicians combine academic excellence with years of hands-on clinical experience, ensuring every patient receives treatment from true dermatology specialists. Every treatment is performed by board-certified dermatologists—not technicians or non-physician providers.


Evidence-Based Aesthetic Medicine

Clinical research is an essential part of our practice. Our doctors actively publish in SCI-indexed international journals and lecture at leading dermatology conferences, allowing us to continuously incorporate the latest scientific advances into patient care.


Personalized Precision

No two faces or skin conditions are alike. We carefully analyze every patient's skin, anatomy, and treatment goals to create individualized treatment plans that maximize results while minimizing unnecessary procedures.


Safety Above All

Beautiful results should never come at the expense of safety. Every procedure is performed under strict medical protocols with meticulous hygiene standards and comprehensive side-effect prevention strategies developed through years of clinical experience.

Our Areas of Excellence

Facial Lifting & Skin Rejuvenation

We provide advanced non-surgical lifting treatments designed to restore youthful facial contours while maintaining natural expression. Our clinic utilizes cutting-edge technologies including CoolSoniq™, Alltite™, TenTherma™, DoubleTite™, Shurink Universe™, Secret RF, and 3DEEP® to stimulate collagen remodeling and improve skin firmness.


Melasma & Pigment Disorders

Melasma is one of the most challenging pigmentary disorders to treat successfully. We provide customized multi-layer treatment strategies for melasma, freckles, solar lentigines, and nevus of Ota by targeting pigment at the appropriate skin depth while minimizing recurrence.


Non-surgical Hair Restoration

We offer comprehensive medical treatment for both male and female pattern hair loss using evidence-based injection therapies, scalp regeneration programs, and individualized treatment protocols that promote healthier, stronger hair growth.


Pore Refinement & Skin Texture

Enlarged pores are often caused by excessive sebum production, collagen loss, or skin laxity. Our combination treatments improve skin texture by tightening pore walls, stimulating collagen production, and restoring healthier skin architecture.


Acne Scar & Scar Revision

Our physicians specialize in treating challenging acne scars and surgical scars using highly precise laser technologies, Nano CROSS techniques, subcision, and regenerative procedures designed to improve skin smoothness while preserving surrounding tissue.


Acne Management

From inflammatory acne to post-acne redness and pigmentation, our comprehensive treatment programs address every stage of acne through medical therapy, comedone extraction, vascular laser treatment, and pigmentation management.


Botox & Dermal Fillers

Our philosophy is enhancement rather than exaggeration. With detailed anatomical knowledge and refined injection techniques, we create natural facial harmony that enhances each patient's unique features without an artificial appearance.

Our Philosophy

Authentic Treatment

We believe in recommending only treatments that are scientifically supported and genuinely beneficial for each patient. Rather than promoting unnecessary procedures, we focus on delivering treatments that produce meaningful, lasting improvements.


Compassionate Care

Every patient arrives with unique concerns and expectations. We listen carefully, communicate honestly, and ensure that every treatment journey is comfortable, transparent, and reassuring from consultation through recovery.


Safety Before Everything Else

Even the most advanced procedure loses its value if safety is compromised.

At YSBB, we regard every potential side effect from the patient's perspective. This philosophy drives our rigorous hygiene protocols, comprehensive risk assessment, and proprietary side-effect prevention system. When a procedure is unlikely to benefit a patient—or presents unnecessary risk—we simply do not recommend it.
