Ingredient Feature: Kinetin and Zeatin
Nature’s inherent processes have been a fascination for centuries for those in medicine—we study sharks for answers to cancer, plants for remedies to pain, we even use eggs to culture everything from vaccines to cosmetic facial injectables—the list goes on and on.
Among nature’s fascinating processes is cytokinesis, a plant’s ability to promote renewed cell division. The study of this process has inspired scientists to incorporate plant-based growth factors called cytokinins into topical skin care.
Two powerful types of cytokinins are Kinetin and Zeatin. Both Kinetin and Zeatin have been shown to be effective in improving the appearance of aging skin and are the powerhouse ingredients in one of Obagi’s newest product lines designed for those with sensitive skin, the Gentle Rejuvenation System.
When researching the plant DNA-derived ingredient Kinetin, scientists discovered that this plant-based growth factor prevented plant leaves from drying out and withering. Soon, they realized the potential benefits Kinetin could have in skin care; they discovered that when used topically, Kinetin gently, yet effectively helps keep skin looking smooth and radiant.1 In as early as 6 weeks, Kinetin has been shown to diminish spots by an average of 60%2 and in 24 weeks patients saw a 26% increase in skin’s ability to retain moisture3.
Zeatin is RNA-derived from immature corn kernels and occurs naturally in plants. When used in skin care, Zeatin has been shown to improve skin appearance including roughness, fine lines and wrinkles, and reduce blotchiness after just 12 weeks4.
The powers of nature are incredible. Every day we continue to learn how natural ingredients and processes can improve our health and our skin. You can learn more about the benefits of both plant-based growth factors and multi-potent embryonic stem cell growth factors from this previous post on our blog.
