Essential oils are primarily utilized in cosmetology treatments for their therapeutic benefits and pleasant scents. These natural extracts from plants contain various compounds that can produce emotional, physical, and psychological benefits. For example, oils like lavender can promote relaxation, while citrus oils may invigorate and energize the senses. The pleasant aromas of these oils also enhance the overall experience of beauty treatments, contributing to a sensory environment that can improve clients' moods and promote a sense of well-being.

While other options touch on important aspects of cosmetic formulations and treatments, such as color and texture, they do not capture the primary reasons for incorporating essential oils in a beauty context—i.e., their holistic benefits and aromatic properties. Essential oils are not typically used as preservatives in cosmetic products when synthetic preservatives are more effective for that purpose.
