Sylk is the only Natural Personal Lubricant made in New Zealand from an extract from the Kiwifruit Vine. Because it is a 100% natural water-based lubricant, it provides vaginal lubrication for women who experience vaginal dryness due to menopause, pregnancy, chemotherapy or radiation treatments, or any number of other reasons. Sylk Natural Personal Lubricant has the ability to simulate normal mucosal secretions, making it highly effective as a personal lubricant. The pH of Sylk is similar to that of the vaginal area, which is slightly acidic, so it is extremely gentle and non-irritating to delicate tissues.
