Enessa's Commitment to Purity- our complete aromatherapy product line uses only the highest quality essential oils available, continuing Enessa's dedication to excellence and purity. Synthetic or inferior oils, common in many products claiming to be aromatherapy, are strongly rejected by Enessa because they merely imitate the fragrance of essential oils, while containing no healing properties. Enessa practices the utmost care in protecting and preserving the integrity of its products by using dark cobalt blue glass bottles. At Enessa, we are constantly driven by our desire to achieve perfection in our products while bringing you healthy, beautiful skin, naturally.
