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.
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.
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.
Lina Oh, Pharm.D
Clinical Pharmacist & Formulation Safety Advisor
Lina Oh is a Doctor of Pharmacy and licensed pharmacist registered in both New York and New Jersey, currently practicing as an inpatient pharmacist in New York. Earlier in her career, she worked as a compounding pharmacist alongside dermatologists and OB-GYNs—building personalized formulas for patients and developing a deep, clinically grounded interest in thoughtful, niche skincare.
That dual foundation—hospital-level rigor and hands-on formulation work—shapes how she approaches product science: not just whether an ingredient is effective, but whether it is truly safe, stable, and appropriate for real people in real life.
At YYY LAB, Lina ensures our formulations meet a standard beyond innovation. She reviews ingredient safety, clinical relevance, and how products actually perform outside of a lab setting—so that what we put into our products is not only science-backed, but responsible and meaningful for everyday use.
