ProloGel® Pain Gel ("Green Label") is our original topical, pain-relieving formula. ProloGel® works differently! ProloGel's patented method of treatment and combination of key ingredients are intended to provide relief by supporting normal nerve function in irritated, painful nerves, rather than by temporarily "blocking" or masking nerve signals (e.g. by cooling, warming or stinging in the area, produced by common, over-the-counter products). ProloGel Pain Gels (recognizable by the characteristic green label) are offered in 2 formats: Clear Gel (an almost transparent gel) and Gel-Cream (a firm, white, cosmetic-like texture).
