As a CIDESCO cosmetologist and former chair of the Danish Cosmetology Association, Karen has spent 30 years inside the industry teaching, treating, and advising major brands. She also saw the truth: how money steers decisions, how trends override science, and how marketing silences a woman’s intuition.
After decades of watching the industry profit from manufactured insecurity, she finally said: Enough. Since 2014, Karen has developed Esther’s formulas with chemists and factory laboratories, blending timeless wisdom with radical simplicity. She knows every ingredient’s origin, its purpose, and exactly how it respects your skin’s ecosystem.
