In the Esthetics America & Wellness Pavilion, attendees enjoyed a quieter and more intimate room to try out new products from skin care to make-up airbrush kits.

Within the pavilion I found this fascinating product, Hotshotz reusable heat packs. The heat packs are self-heating using an exothermic reaction. They’re filled with a sodium acetate liquid with an activating button within the liquid. When the button is pressed, it triggers a chemical reaction and the liquid pack quickly turns into a solid and heated pack. This chemical reaction can be seen in the photos above and below within the round heat pack.

It took a few seconds for the product to change into a heated solid. It feels a lot like paraffin when it’s hot and in a solid but flexible state.

The company says the heat packs will stay hot from one to five hours depending on the size of the pack. To get the pack back to a liquid state, you can place the pack in boiling water and it will melt the solid pack. Once its back to room temperature you can activate it again and again, as long as there are no punctures on the pack.

Head packs can be used for massage therapy and physical therapy and can be added to salon and spa services. The packs come in varying shapes and sizes including shapes for your hands, back, shoulders, and face. The company also has cold packs that can be placed in the freezer.
