Medical Advisory Board

Jungwon Park, MD

Medical & Longevity Advisor

Dr. Jungwon Park is an OB‑GYN specialist with 35 years of clinical experience, with additional credentials/training in plastic surgery & aesthetic medicine, and long‑standing expertise in stem cell science, anti-aging and longevity. Her perspective is grounded in a life‑stage truth: skin changes when life changes—and recovery often slows with time.

At YYY LAB, she helps us maintain a quiet but unwavering standard: high performance that still feels gentle. She reviews our concepts for long‑term comfort, balance, and suitability for sensitive, mature skin—ensuring our second Yield, Skincare & Haircare Yield, never sacrifices tolerance for intensity.

What she brings

  • Life‑stage insight for 35+ women’s skin shifts (sensitivity, dryness, resilience)
  • Safety‑first product review and long‑term comfort standards
  • Quiet, evidence‑minded guidance without unnecessary prescription

Sue Kim, MD

Clinical Research & Education Lead

Dr. Sue Kim graduated from medical school in Hungary and holds medical licenses in both Europe(Hungary) and Korea. Trained across different medical systems, she has worked with patients from diverse racial and ethnic backgrounds across Europe and Asia, giving her a globally informed perspective on how skin concerns can present differently by age, ethnicity, and environment.

She joined YYY LAB to answer one question: What evidence can consumers all over the world actually understand and use? Sue translates complex science into practical, real-world guidance—helping connect YYY LAB’s topical and oral approach with clarity, integrity, and everyday usability.

What she brings

  • Clinical insight into teenage to early-adult skin, where sensitivity, breakouts, and barrier imbalance often begin
  • Experience working with patients across diverse racial and ethnic backgrounds in Europe and Asia, shaping an inclusive, global view of skin tolerance and early intervention
  • Evidence translation and responsible claims language
  • Education content that makes daily routines easy to understand and follow

Yeonsook Kim, PhD

Scientific Director, R&D

Dr. Yeonsook Kim holds a PhD in Biotechnology and has led government-funded research as a stem-cell scientist, building her career at the intersection of rigorous laboratory science and real-world application. Her work has focused on understanding how biological systems respond over time—knowledge that directly informs how YYY LAB approaches skin, scalp, and nutritional formulation.

At YYY LAB, Dr. Kim oversees research and development across skincare, haircare, and supplements. Rather than pursuing intensity for immediate impact, she designs formulations around tolerance, stability, and long-term performance—ensuring that active ingredients are not only effective, but also consistently usable.
Her approach extends beyond ingredient selection to the full system: concentration, synergy, delivery, texture, and real-world adherence. This is how YYY LAB elevates both Skincare & Haircare Yield and Supplement Yield—by turning scientific precision into products that support calm, resilient skin and hair over time.

What she brings

  • Research leadership grounded in biotechnology and stem-cell science
  • Formulation systems that prioritize tolerance, stability, and long-term use
  • Integrated R&D across skincare, haircare, and nutritional supplements
  • Science-driven standards that translate laboratory insight into everyday performance
