Provides soothing heat to relieve upper and lower back pain from long hours of sitting or standing. Helps loosen tight muscles, improve mobility, and support recovery from fatigue, strain, and mild spasms.
Tear open the pouch when ready to use.
Peel off the paper to expose the adhesive side.
Stick the Back Relief directly to the affected area.

Iron Powder
This is the main heat-generating ingredient. When exposed to air, iron naturally oxidizes (similar to rusting), which produces gentle warmth. This process allows the patch to deliver consistent therapeutic heat to help relax muscles and ease discomfort.
Activated Carbon
It helps regulate and distribute the heat evenly. It also improves airflow inside the patch so the heating process remains stable and efficient.
Water
Water supports the oxidation process of iron and helps maintain the right moisture level so the heat reaction happens smoothly and gradually.
Salt
Salt acts as a natural catalyst, helping the iron react with oxygen more efficiently so the patch can warm up faster and maintain its heat for longer periods.
Non-woven Fabric
This material is soft, breathable, and skin-friendly, allowing air to pass through so the heating reaction can continue while keeping the patch comfortable when applied to the body.
Heat Sheet Core
The heat sheet core holds the ingredients securely and distributes the warmth evenly, ensuring a stable and consistent heat output throughout the patch's usage time.
Yes. Heat promotes blood flow and can help reduce back muscle tension and discomfort.
Apply it directly over the painful area, not on the spine.
No. For recent injuries, especially within the first 48 hours, cold therapy is typically recommended instead.
Yes, if needed, but avoid overlapping them to prevent excessive heat.
