We use Ecocert preservatives, such as dehydroacetic acid and benzyl alcohol, to maintain the performance, quality, and freshness of our formulas. We refrain from using paraben preservatives in any of our products. Parabens have been linked to health concerns such as reproductive and developmental toxicity. Given Briogeo refrains from using potentially harmful preservatives or chemical stabilizers, the color or scent of our products may change over time and this is completely normal due to the nature of the essential oils and natural extracts we use in our formulas.
