The best measure for us to know if an aroma has achieved its therapeutic role is our nose. Once we start to feel uncomfortable with one specific aroma, our olfactory sense is telling us that our body already got what it needed for that part of the day. Then, we just have to take the necklace off.
Marco Ortega Personal Diffusers give us freedom to use Aromatherapy according to our will and needs.
By changing the cotton, we can change the oils as many times as we want throughout the day.
