Nature’s inherent processes have been a fascination for centuries for those in skin care. Plant-based growth factors provide an example of recent fascination.  These cytokinins, as they are also called, have been synthesized and incorporated into topical skincare.

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 key ingredients in Obagi’s product line designed for those with sensitive skin, the Gentle Rejuvenation System

When researching the 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 synthesized and used topically in a 0.1% concentration, Kinetin gently, yet effectively can help keep skin looking smooth and radiant.1 In one study, 72% of patients reported an improvement in skin texture at 24 weeks after using 0.1% Kinetin cream twice daily with an SPF 30 sunscreen.1 In another study using a 0.1% Kinetin lotion, patients saw a 26% increase in skin’s ability to retain moisture in 24 weeks.2 

Zeatin, which occurs naturally in plants, was originally derived from RNA in immature corn kernels. It is now synthesized and added to topical skincare products. A study has shown that a 0.1% concentration of Zeatin used twice daily with an SPF 30 sunscreen in the morning, can improve skin appearance including roughness and fine lines and wrinkles in as little as 12 weeks.3

To discover how Kinetin and Zeatin could help to improve your sensitive skin, ask your skin care physician about the Gentle Rejuvenation System
