Yes, like any other cosmetic or skincare product, argan oil does have an expiration date. However, argan oil has a relatively long shelf life compared to many other oils due to its high levels of antioxidants and vitamin E, which help to extend its stability.

Typically, unopened and properly stored argan oil can last for about 1 to 2 years. However, once opened, the oil's exposure to air, light, and heat can accelerate its degradation. Therefore, it is recommended to use opened argan oil within 6 to 12 months to ensure its freshness and efficacy.

To extend the shelf life of argan oil, it is important to store it in a cool, dark place away from direct sunlight and heat sources. Additionally, keeping the bottle tightly sealed after each use can help minimize air exposure and maintain the oil's quality for a longer period.

It's worth noting that if you notice any changes in the color, smell, or texture of the argan oil, it is likely past its expiration date and should be discarded. Using expired or rancid oil may not provide the desired benefits and could potentially cause skin irritation or other adverse reactions.
