ABOUT YYY LAB

Beyond Surface Skincare

People choose nutrients to support different parts of the body—because health is not only about what we see superficially, but what we build over time beneath the surface.
YYY LAB asks the same question of skin.

Skin is more than what we see—it is a living organ shaped by time, habit, 
and internal balance.
That’s why we don’t believe in skincare that works only at the surface. 
At YYY LAB, we support skin from the outside and from within, designing topical care and oral nutrition to function as a single, thoughtful routine.
This is our inside-out, holistic approach.
The three Y’s in YYY LAB stand for Yield—the results that are built gradually, often invisibly, across the entire system.

Our Three Yields

01 PRODUCTION YIELD

Great products require more than ideas—they require repeatable quality.
At YYY LAB, we build efficient and consistent systems, from ingredient selection to production standards. By reducing unnecessary waste and improving scalability, we ensure that high-performance skincare, haircare, and supplements can be made reliably and responsibly, so consistency is not a luxury, but a given.

02 Skincare & Haircare Yield

More ingredients don’t always mean better results. 
What matters is how the body receives them.
We design skincare and haircare with sensitive skin and scalp in mind—carefully considering texture, ingredient synergy, comfort, and effective delivery within the skin and scalp barrier. Whenever possible, our formulations are supported by human-use evidence, ensuring performance that feels as good as it works.

03 Supplement Yield

For supplements, “good ingredients” are only the beginning.
We focus on ingredient quality, dosing logic, and synergistic formulation
—along with real-world adherence—so nutrients are designed 
for practical absorption and long-term use, supporting skin and hair health 
from within.

Founder Story

Junsik Kim

Founder & CEO

Trained in Electrical Engineering, Junsik Kim built his career designing systems where efficiency, reliability, and measurable outcomes mattered. His work across Samsung C&T (Trading), POSCO International, and Cheil Worldwide gave him firsthand experience in global supply chains, large-scale operations, and brand systems built to perform consistently—not just once, but over time.
Alongside his engineering and business career, Junsik worked as an NSCA-certified Sports Nutrition Coach in both the U.S. and Korea, and as a government-certified sports instructor. There, he observed a pattern that would later shape YYY LAB: results are rarely driven by intensity alone, but by how efficiently the body can absorb, tolerate, and sustain a system.

In 2019 Summer, he founded Colorful Solution(YYY LAB is brand own & operated by Colorful Solution) with a question rooted in engineering logic:
In skincare and health, why do we focus on how much we add, rather than how much actually works?
Drawing from his engineering background, Junsik introduced the concept of Yield into skincare and healthcare—defining it as the measurable return between formulation input and real biological response. At YYY LAB, Yield is not about maximal concentration, but about maximal usability: how effectively a product performs once it meets real skin, real routines, and real life.
As Founder and CEO, Junsik sets the standards that guide YYY LAB across skincare, haircare, and supplements—ensuring that every product is built on systems that prioritize efficiency, tolerance, and long-term consistency over short-term impact.

What he brings

  • An engineering-led approach to skincare and healthcare systems
  • The introduction of Yield as a framework for measuring real-world efficacy
  • Scalable, globally minded operations rooted in consistency and reliability
  • A philosophy that values sustainable performance over momentary intensity: Habit‑driven communication that turns skincare & haircare 
into a sustainable routine
