Marcel Voss, CEO of Dermatest
Marcel Voss is the CEO of Dermatest, an independent dermatological institute with a long history in Germany.
He holds a degree in sports economics and currently leads the institute's management and strategy.
Voss is committed to maintaining rigorous scientific standards,
placing the highest priority on reliability, objectivity, and transparency in dermatological and cosmetic safety testing.
In 2025, Voss visited Korea for direct discussions with only four selected companies.
DA EFFECT was recognized as one of those special partners.
This indicates that DA EFFECT's product philosophy aligns with Dermatest's strict testing standards and evaluation principles.
What was especially impressive about DA EFFECT was the remarkable stability shown from the first use. Even among subjects with reduced skin barrier function, a tendency toward less perceived irritation was confirmed. The fact that this product earned a "Very Good" rating and passed the sensitive-skin test demonstrates that DA EFFECT formulas are genuinely gentle on skin.
The fact that this product was developed with delicate skin conditions in mind shows that our testing goes beyond a simple sensory evaluation and takes a truly customer-centered approach. We hope brands like DA EFFECT build trust through Dermatest and become a clear standard for consumers.
