Hi Reddit!
I'm Gucheol Kwon, Ph.D., CTO at ROUND LAB, a Korean skincare brand.
Before joining the cosmetics industry, I earned my Ph.D. researching drug delivery systems, including cancer-targeting nanoparticles.
Today, I lead research on skin barrier recovery, hydration, microbiome science, healthy aging, and next-generation sun care.
It's live here now in r/SkincareAddiction for anyone interested in asking a question:

I will be back at 8 PM ET today (June 22) to answer questions.
I recommend asking in advance.
Please ask there. All questions are much appreciated!
We can talk about things like:
- Skincare ingredients and how they interact with the skin barrier
- Sunscreen, UV protection, and how sun filters actually work
- My day-to-day work as a skincare researcher and what it’s like in the industry
