 Expiry Dates
Some essential oil manufacturers print the expiration date on their bottles. This gives you a clear indicator of how long you can use your oil. If you are buying essential oils from the store, look on the bottle to see when it expires, and choose the bottle with the furthest future expiry date if you don’t plan on using it quickly. Ask the individuals in the store if there is a way to find the date if it is not clearly marked.
Keep in mind that the oils you buy were not created on the day you bought them,
so try to purchase your oils from a store or supplier that keeps their product moving regularly. In this way, you aren't purchasing an essential oil that is already far along on the way to expiration. If there is no expiry date on the bottle, keep a list of all your essential oils and when they were purchased. This will allow you to quickly check how long you have had an oil before using it each time.

General Rules
There are three factors that cause essential oils to lose their potency and effectiveness quickly. These are light, oxygen and heat. The best way to keep your oils in the best condition possible is to fight these factors by storing your oils properly. To counteract exposure to light, buy your essential oils when possible in amber glass bottles (so the light does not penetrate the bottle as it does with clear glass) and keep them in a dark place. Keep your essential oils in a cool area, or in the refrigerator if you have room. Always keep your bottles tightly closed when not in use, and don’t leave them sitting around with the lid open for any amount of time. Protect your essential oils from contamination by not using rollers that can pull random particles back into the bottle with your essential oils. Essential oils have a specific shelf life. Oils won’t instantly go bad on the expiry date, but at that point they are on their way to losing their potency. Learn this general information so you know how long to keep your essential oils, and when to replace them.
