For the best overall experience, we recommend enjoying our bars within 6 months of purchase, since we only use natural essential oils and the scent may gradually fade over time, unlike synthetic fragrance that can last longer. Even if the scent has faded over time, the efficacy of our bars does not decrease. In fact, the bars are known to become gentler with age, while also becoming harder, longer lasting, and able to lather even more beautifully over time. Before use, store the bar in a cool, dry place away from direct sunlight. For bars past one year, use a simple sight and smell check before use.
