When the term “fragrance” is used on a product’s ingredient list, it may refer to one ingredient or a blend of natural and/or synthetic substances that provide a distinct smell to the product. Individual fragrance components may also be found on the ingredient list, such as linalool, limonene, geraniol, benzyl benzoate, benzyl salicylate, cinnamal, and more. Most fragrance ingredients impart a scent through a volatile reaction. In addition to imparting a pleasant odor, fragrance ingredients can be used to mask unpleasant smells from other ingredients. Fragrances can also be used to signal cleanliness and freshness, as well as create a certain mood, alleviate stress, or promote a sense of wellbeing. What’s important to keep in mind with fragrance is that both natural and synthetic ingredients pose the risk of sensitization and irritation for all skin types, not just those with sensitive skin.
