What effect does light exposure have on essential oils?

Light exposure can degrade the quality of essential oils, which is the correct understanding of this effect. Essential oils are sensitive to environmental factors, and light can cause chemical changes in the compounds that make up the oils. This degradation can lead to a reduction in therapeutic efficacy and alterations in scent and overall quality.

When essential oils are exposed to light, especially UV light, it may lead to the breakdown of key components, making the oils less effective for therapeutic purposes. This is why essential oils should be stored in dark, cool places to preserve their integrity.

The other options do not accurately reflect the relationship between light exposure and essential oils. For instance, light does not enhance the potency of oils nor does it increase their aroma; instead, it has the potential to diminish their effectiveness. Similarly, it is not true to say that light has no significant effect, as the impact of UV light on these products can be detrimental. Thus, understanding the importance of proper storage away from light can help maintain the quality and efficacy of essential oils.
