Levan A Natural Anti-Aging Humectant
What is Levan? Levan is a naturally occurring bio-polymer a polyfructose. Levan molecules are formed from sucrose by an enzymatic process. Typically structured as β-2,6 carbon atom bonds, they are in fact edible, prebiotic fibers, appearing as a whitish, slightly viscous solution. Efficacy & uniqueness of these fibers are derived from their structure & MW distribution. Combining low & high MW, Levan performs as an outstanding film-forming Humectant. Levan 2, 6 bonds Inulin 1,2 bonds
Levan Production process & Safety Production process: enzymatic conversion of sugar. Conducted under strict GMP conditions. Enzyme: Non-GMO, Infoxgen compliance; certificated European enzyme manufacturer; enzymatic process doesn't require growth medium; culture is not involved in the production of levan. Contamination control: Pasteurization at the end of the process. Preservation: Potassium Sorbate. INCI name / 28-30% Levan: Levan/Fructose/Glucose/Sucrose (and) Citrate Buffer Composition: Levan fiber, sugars, buffering agent, sorbate. Non-Irritation / Dermatology Tested Certified: Checked up to 10% conc. in body cream formulations/ as ingredient in direct contact with skin.

Clinical Research : Levan Efficacy vs hyaluronic acid Performing Laboratory: The Israeli Institute for Skin Research Principal Investigator: Prof. Sarah Brenner, Dermatologist Sponsor: Gan Shmuel Foods Ltd. 1 Objective: To compare between the efficacy of Levan solution (28-30%) 1.6%, Hyaluronic Acid (HA) 0.2% and a Compound of Levan solution 0.8% + Hyaluronic Acid (HA) 0.1% in Anti Wrinkle Treatment Test materials: 1. Levan solution (28-30%) 1.6% 2 Research groups: 2. Levan solution 0.8% + HA 0.1% Body cream Group-A (Levan 0.8% + HA 0.1%) 3. HA 0.2% Body cream Group-B (Levan 1.6%) Body cream Group-C (HA 0.2%) 23 participants
Clinical Research Clinical assessment The following examinations will be performed at baseline (T0), before using the materials, And at the end of the test (T1), after four weeks of using the materials: 1 2 3 4 Visual skin assessment by the investigator in a scale of 0 5, with reference to wrinkles appearance, wrinkles surface area and depth. Measurements: Hydration level by Corneometer, Courage & Khazaka, CK. constant pressure on skin/ hydration measurements. TEWL (the ability not to harm the skin barrier) by Tewameter TM 300, Courage & Khazaka, CK. Measurement will be recorded after stabilization of the curve of the results in real time. Photography Color photography by Visioface 1000 D, Courage & Khazaka, CK from the front and the sides of the face Wrinkle analysis Selected wrinkles area will be analyzed by Visioface 1000 D, Courage & Khazaka, CK.
