How should I store this bottle to keep the oil effective, and how long will it last? — Water-soluble essential oil PINE, 30 ml "AromaSaules"

To maintain the quality and aromatic potency of the pine essential oil blend, store the bottle in a cool, dark place away from direct sunlight and heat sources, such as windowsills or near radiators. Exposure to light and high temperatures can accelerate the degradation of the volatile compounds that give the oil its characteristic sharp, woody scent. Keep the cap tightly sealed when not in use to prevent oxidation and evaporation. While cosmetic products like this typically have a shelf life of several months to a few years when stored properly, essential oils are concentrated and their top notes may diminish over a long period. For the best sensory experience, it's advisable to use the product within a year or two of opening. Always check for any changes in scent, color, or consistency, and discontinue use if the product appears altered.
