AquaEssentz are pure natural essential oils encapsulated using our nanoencapsulation technology at stated concentration within a fully water-based sprayable formulation. Essential oils should not be used without dilution as they could be too strong and cause skin irritation problems. Each one of us may react differently to different essential oils. Our products are convenient for users as you can either apply AquaEssentz directly on your skin (but please do a skin patch test first to ensure you do not have adverse reaction at this concentration) or it can easily be diluted with distilled water to your desired concentration. Typical essential oil users would dilute their essential oils using carrier oils like Jojoba oil which can be too oily for the skin and not sprayable. Some users may dilute it in alcohol which has a better skin feel and can give a good spray.
