Texas Cosmetology License Practice Exam

Question: 1 / 400

Which of the following is an example of a barrier cream used in cosmetology?

Coconut oil

Aloe vera gel

Petroleum jelly

In the context of cosmetology, barrier creams are designed to create a protective layer on the skin to prevent irritation and protect against harmful substances. Among the options provided, petroleum jelly is the most recognized as a barrier cream. It serves as an occlusive agent, trapping moisture and preventing exposure to external irritants.

Coconut oil, while beneficial for its moisturizing properties, does not serve the same barrier function. Aloe vera gel provides soothing properties but does not create a protective barrier like petroleum jelly. Vitamin E oil is often used for its skin-nourishing benefits and antioxidant properties but does not have the thick, occlusive effect characteristic of barrier creams.

Understanding the properties of these substances is essential for cosmetology practice, particularly when considering skin protection during treatments or procedures.
