ShiKai Borage DiabetiCare Omega-6 Foot Cream is a non-prescription, clinically proven formula designed to relieve dry and cracked skin, specifically addressing the fundamental cause of dry skin in diabetics. The cream aims to supply omega-6 oils directly to skin cells, with a focus on borage oil. This ingredient contains 24% gamma-linolenic acid (GLA), a vital omega-6 fatty acid. In addition, it also contains components like l-ergothioneine, vitamin C & vitamin E. Borage Oil is highlighted as the richest source of this omega-6 oil, though it is noted to be difficult to harvest, stabilize, and therefore, is expensive and rarely used. L-ergothioneine is described as an amino acid and a powerful antioxidant, L-ergothioneine assists cell membranes in transporting omega-6 to where it can be used. It is also said to promote epikinesis, or skin energy. Vitamin C is an antioxidant with well-known positive effects on the skin. In this formula, vitamin C works together with L-ergothioneine to create an effective fatty acid transport system. Vitamin E is another antioxidant that serves a dual purpose. It stabilizes borage oil, ensuring its effectiveness, and is known to be beneficial for the skin. The formula is mentioned to be fragrance-free, making it suitable for individuals with diabetes. It is recommended by diabetes educators and dermatologists.
