Tres Spa uses a custom blend of essential plant oils to create a truly unique and distinctive product. In designing the scent blends, we took our inspiration from nature. Makes sense since the products created are all from natural ingredients. Each of the four main scent lines represents the four elements of Fire, Water, Earth, and Air. Oils are selected for a number of reasons, the ability to add value to the overall aroma, the therapeutic qualities of the oil, and the ability to blend well with the other natural ingredients to create a valuable product for you to use. Because we use pure essential oils for the scents, the products are more delicate in that the scent will not be overpowering or tend to hang heavy around you or in a room. It's difficult to really understand a scent without being able to smell it for yourself, and since there is no such thing as scratch and sniff for the world of electronics, we have provided a brief summary for each of the blends written by the creator of the blend.
