What are essential oils often used for in skincare?

Essential oils are widely recognized in skincare for their dual function: they provide benefits for skin health while also enhancing the sensory experience through their aromatic properties. The correct choice reflects this holistic use by highlighting both aromatherapy and skin benefits.

In the context of skincare, essential oils can offer a range of therapeutic properties such as antiseptic, anti-inflammatory, and calming effects. For instance, tea tree oil is renowned for its antibacterial qualities, making it useful in treating acne, while lavender oil is celebrated for its soothing effects, promoting relaxation and potentially aiding in skin healing.

The other choices suggest uses of essential oils that do not fully capture their potential. Limiting essential oils to only fragrance overlooks the various therapeutic effects they can offer, which are essential to skincare practice. Similarly, using essential oils merely for adding color or as a preservative does not align with their primary properties and benefits in skincare formulations. Overall, the use of essential oils in skincare encompasses a comprehensive approach that includes both their aromatic qualities and their therapeutic effects, validating the importance of the combination reflected in the correct answer.
