From Patient to Vision
Founder Alex Lee, once a patient of Dr. Donghyun Yoon (now CISL CTO), experienced the benefits of advanced procedures—but also their limits: cost, downtime, and inconsistency. Together they asked, “Could clinic science be transformed into daily skincare?” CISL was born from that vision.
Clinical Proof
At CISL, every formula begins and ends with clinical evidence. Designed from protocols used in real dermatology clinics, our products undergo independent 3rd-party testing at certified international labs—covering lab assays and human trials. The result: measurable improvements you can trust, backed by science not marketing.
Key Ingredients
At CISL, hero ingredients are clinically engineered, not just listed. Proven actives like PDRN and exosomes are combined by our R&D team into proprietary formulas, then validated through independent 3rd-party testing for purity and efficacy. These are the signature components behind every CISL product.
CISL Lab
At CISL Lab, our R&D team creates proprietary TM technologies that set each product apart. From AGELOCK™ delivery systems used across all formulas, to BARRIER™ capsules, INFUSHOT™ micro-infusion, DUOMIX™ dual chambers, and WRINKLE CORREXION™ high-dose serums—every technology is scientifically engineered for deeper performance and unique results. This is where clinical science becomes formulas only CISL can deliver.
