Zelens represents a new generation of skincare developed using breakthrough scientific research in the biological functions of the skin. Our innovation is driven by founder Dr. Marko Lens' 20 years of research in skin ageing, his clinical experience as a plastic and reconstructive surgeon and his deep knowledge of formulation chemistry combining active biotechnology ingredients with pure molecules derived from botanicals. Combining biotechnology and botanicals is not enough. Zelens products combine powerful high-performance active biotechnology ingredients with the unique blend of plant-derived molecules with potent anti-ageing and healing properties. But simply combining ingredients derived from both sources does not create truly effective skin care. Ingredients must be carefully selected, science-backed and integrated in a formula to work in synergy. Only the exact balance and synergistic action of all ingredients can effectively trigger cellular processes necessary for skin regeneration and repair. The sophisticated technology of our formulations including multiple ingredients that work in balance and synergy is essential to the remarkable effectiveness of Zelens products. The leading edge in skin care. Always. Zelens' consistent skincare innovation is the result of Dr. Lens' continuous research, development and testing. Every Zelens product represents the most advanced, most effective skincare technology available anywhere. Other good things to know: Zelens products are extensively tested for safety and efficacy by renowned independent laboratories. Zelens uses no animal testing and no animal-derived ingredients. Zelens uses no parabens. Zelens is committed to eco-responsibility.
