Shirley Price Aromatherapy is renowned for its innovative approach but not where it comes to anti bacterial preservatives. We are in the forefront of Soil Association certifed organic skincare but only with the very best of cosmetic chemistry and ingredients in partnership with first class knowledge. For example we use the very strongest and purest of grapefruit extract as a natural preservative. Where a shelflife of more than 12 months is envisaged we continue to use the parabens system and recommend it. Customers have been known to use our Essentia daily skincare routine pack for 5 years. A little goes a long way!
