Final answer:
A diamond tip microdermabrasion device is known as d) non-particle microdermabrasion, which uses a diamond-tipped wand for skin exfoliation, as opposed to crystal-emitting methods.
Step-by-step explanation:
A diamond tip microdermabrasion device is correctly known as d) non-particle microdermabrasion. The term refers to a method that uses a diamond-tipped wand for exfoliation instead of the crystal-blasting technique. In contrast, hydradermabrasion involves water and oxygen along with exfoliation, crystal microdermabrasion uses a crystal-emitting handpiece, and particle microdermabrasion could be another name for the crystal method, although this term is less common.
Diamond microdermabrasion is preferred by some because it is seen as a cleaner and more controlled method of skin exfoliation that helps to reduce skin impurities, such as fine lines, wrinkles, and acne scars. This type of device makes it easier to avoid potential inhalation of crystals, making it a safer option for both the technician and client.
