Using essential oils improperly can lead to skin irritation or allergic reactions, making this the correct answer. Essential oils are highly concentrated plant extracts, and when applied directly to the skin without proper dilution or in excessive amounts, they can cause adverse effects. Individuals may experience redness, burning, or rashes, indicating an irritation or allergic response to the components in the oil.

Understanding how to properly use essential oils, including proper dilution ratios and suitable methods of application, is crucial to avoiding these side effects. Such knowledge helps users safely enjoy the benefits of aromatherapy without risking skin damage or discomfort from an allergic reaction.
