Milady Esthetics State Board Practice Test

Which of the following statements about ultrasound technology is correct?

1. It is only used for skin tightening

2. It enhances product penetration

3. It is ineffective for cellulite reduction

4. It can only be used on the face

The correct answer is: It enhances product penetration

The statement that ultrasound technology enhances product penetration is accurate because ultrasound waves create micro-vibrations in the skin, which facilitate the absorption of ingredients from topical applications into deeper layers of the skin. This process, known as sonophoresis, utilizes sound waves to increase permeability of the cell membranes, allowing for more effective delivery of products, such as serums or treatments, that aim to improve skin hydration, texture, and overall appearance. The use of ultrasound in esthetics has been well-researched and is a common practice in various treatments to optimize the benefits of skincare products. In contrast, other statements may suggest limitations or inaccuracies regarding ultrasound technology. For example, while it is beneficial for skin tightening, its application is not confined to this purpose alone, as it can also address a variety of skin concerns, including product application and enhancement. Additionally, ultrasound technology has been shown to be effective in various contexts, and it is not restricted to facial treatments; it can also be utilized on other body areas for various aesthetic purposes, including cellulite reduction.
