Four targeted actives, no filler. L-Arginine drives circulation into the area you rub it into; Arnica Montana and MSM soothe soreness and support the tissue around it; Magnesium Chloride eases the muscle tension that builds up when something has been hurting for months. No proprietary blends — what's on the label is what's in the jar.

It's transdermal. Rubbed into the hands, or over the low back and down the leg, the actives absorb locally into the tissue right where you put them — instead of being swallowed and diluted across your whole body like a pill. That's the whole point: getting soothing, circulation-driving actives to the exact spot that burns, the way a pill can't.

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 — Arnica, MSM, Arginine and Magnesium — made to absorb in and build up with daily use, soothing the area and driving circulation rather than just masking a signal for an hour.

A small amount worked into the hands — palm, wrist and fingers — or rubbed over the low back and down the side of the leg, morning and night. Massage it in until it absorbs and let it dry before dressing. Ideally after a warm shower, when your skin is most open. 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 — a quieter evening, an easier first hour of the morning — tends to build over the first couple of 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 hands or your back feel — calmer, more comfortable, easier to get through the evening — just email us and we'll refund your first order. No questions asked, no hoops.
