From Patient to Founder
CISL SEOUL began with a simple encounter between a patient and a surgeon. Founder Alex Lee first met Dr. Donghyun Yoon, a plastic surgeon, as his patient—seeking solutions for deep lines and facial contours. The experience revealed both the power of advanced procedures and their limits: high cost, downtime, and accessibility.
A Question That Sparked a Vision
During years of treatments, Alex asked Dr. Yoon a pivotal question: “Could the science of clinical procedures be translated into daily skincare?” While skincare could never replace the instant effects of in-clinic treatments, Dr. Yoon believed it could embody the same logic—targeted pathways, precise concentrations, and protocols that deliver cumulative, visible results.
From Clinic to Daily
This shared vision led Dr. Yoon to join CISL SEOUL as CTO. With his expertise in structural aging and tissue science, and Alex’s perspective as both patient and founder, CISL was built on one principle: skincare should not promise dramatic one-time miracles, but deliver reliable, protocol-driven results that compound over time.
