Four targeted actives, no filler. L-Arginine drives circulation into the tissue at the base of the finger; MSM supplies the sulfur that connective tissue is built from; Arnica Montana soothes the soreness and puffiness around the tendon; Magnesium Chloride eases the tension that builds up through the palm and hand. No proprietary blends — what's on the label is what's in the jar.

It's transdermal. Worked into the base of the finger and the palm, the actives absorb locally into the tissue right where that tendon runs — instead of being swallowed and diluted across your whole body like a pill. The tissue around a finger tendon has a modest blood supply of its own, which is exactly why getting soothing, circulation-driving actives directly over it matters.

Most drugstore creams are a single ingredient that sits on the surface and fades — a cold or warm distraction you keep reapplying. Lumen is four targeted actives — Arginine, MSM, Arnica and Magnesium — made to absorb in and build up with daily use, soothing the finger and driving circulation into the tissue rather than just masking a signal for an hour.

A small amount worked into the base of the affected finger, along the tendon and down into the palm — morning and night. Massage it in until it absorbs. Easiest first thing before you get out of bed, and again before sleep. Because it works by building up with consistent use, doing it daily is what matters most.

Most people feel a cooling, soothing sensation on contact from the very first use. The bigger shift — less stiffness first thing in the morning, an easier time opening the hand — tends to build over the first few weeks of daily use, and keeps compounding from there. It's a daily ritual, not a one-time fix.

Use it for a full 30 days. If you don't notice a real difference in how your hand feels — looser, more comfortable, easier to open — just email us and we'll refund your first order. No questions asked, no hoops.
