Burns typically occur when an external heat source (like a heating pad/hot water bottle) is too hot against the skin. Core Patch works differently: the ingredients interact with your body to stimulate your own internal heat production. Because the heat is generated biologically rather than chemically, the risk of a traditional burn is effectively eliminated.

Standard heat packs use iron powder to create chemical heat via oxidation. Core Patch is formulated with natural Capsaicin to stimulate thermogenesis and improve blood circulation. It is free from iron, heavy metals, and harmful chemicals, making it safe for prolonged contact.

Yes. Core patch is certified as non-irritating and is designed to be applied directly to the skin. In fact, it must touch your skin to activate the receptors (it will not work over clothing). At just 0.45mm thick, it is virtually invisible under your outfit.

You will typically feel the temperature rise 1–2 hours after application, and the thermogenic effect lasts for approximately 8 hours. If you do not feel temperature changes after 8 hours, you may remove it. Please note this is a single-use product and cannot be reused.

Because this product relies on your body's metabolic response, the intensity can vary based on age, body fat percentage, and basal body temperature. In rare cases—such as areas with higher body fat or if your body is extremely cold—you may not feel the heat immediately during the first use.

• Recommendation: We suggest trying it up to 3 times to allow your body to acclimate.
• The "Wrist Test": If you want to check if the patch is working, try applying it to a more sensitive area, such as the back of your neck, wrist, or inner arm.

The product is good for 36 months (3 years) from the date of manufacture.
