The Karin Herzog skin care line was developed in Switzerland by Dr. Paul Herzog, an eminent physician and scientist. His initial research on the stabilization of oxygen was solely designed for medical use. Then his wife, Karin Herzog, found another application. Herself a qualified beautician, she tested the products on her face. Within days, she noticed that her skin was looking refreshed and her complexion was clearer and more luminous. With these results in hand, Mrs. Herzog suggested to her husband that he apply his marvelous discovery to skin care. The Herzogs established the Karin Herzog skin care line, and patented the formula to stabilize oxygen in emulsifying creams so the skin can absorb and benefit from its healing powers. The rest is history - Karin Herzog is now the best oxygen skin care line available today! Still made in Switzerland, these products will keep your skin looking young, radiant, and healthy
