Which of the following is true about microdermabrasion?

1. It stimulates the dermal layer

2. It involves a deep penetration of ultrasound

3. It produces ultraviolet light

4. It is used exclusively for hair removal

The correct answer is: It stimulates the dermal layer

Microdermabrasion is a non-invasive skincare procedure that exfoliates and removes the superficial layer of dead skin cells. It primarily works on the epidermal layer of the skin, promoting the regeneration of new skin cells and stimulating collagen production. This is why the statement that microdermabrasion stimulates the dermal layer is true. Option B is incorrect because microdermabrasion does not involve a deep penetration of ultrasound; it typically uses abrasive materials or a mechanical device to exfoliate the skin. Option C is incorrect because microdermabrasion does not produce ultraviolet light. It is a mechanical exfoliation technique and does not involve any light production. Option D is incorrect because microdermabrasion is not used exclusively for hair removal. It is primarily used for improving skin texture, reducing fine lines and wrinkles, minimizing pore size, and treating acne scars.
