The practice of activating your senses. Seeing, smelling, and touching delightful things releases dopamine, the brainâs feel-good hormone, and brings you back to the here and now. Let your senses work their magic. Lifelines blends are specially created for an extraordinary aroma experience using 100% pure essential oils and sustainably sourced botanicals from around the globe. They are free from parabens, phthalates, dyes, and formaldehyde donors and blended.
