We do our best to source the freshest and highest quality ingredients, following aromatherapy safety guidelines. We use safe dilutions and oils for the intended individual and use to reduce the chances of any reaction. Naturally some individuals are more susceptible to irritation than others such as babies, children and the elderly. Please read application instructions before use and conducting a test patch prior to use is highly recommended. Test on a small area of the forearm and wait for 10–15 minutes to be sure that no irritation reaction occurs. If irritation occurs, please discontinue use. We cannot guarantee you will not experience a skin reaction and cannot be held responsible if this occurs. Irritation will be localised to the areas where the product has been applied. This generally occurs on first exposure with an immediate reaction, such as a rash (raised/inflamed/bumpy/itchy skin). If the reaction is not localised and can be noticed in other places other than the area you have applied the product and is not very noticeable upon first use, this is most likely a sensitisation of an essential oil component. Sensitisation is an allergic reaction of the immune system. It is highly likely than it will take more than one exposure for this reaction to occur. We follow the international cosmetic labelling standards which means that any known potential skin allergens contained within a product are listed on the label. These components have been so widely used in the cosmetic industry that an individuals exposure to them are significant, which increases the likelihood of sensitisation over time.
