Final answer:
Microdermabrasion is performed during the treat phase of a facial treatment, where it serves to exfoliate the skin, preparing it for subsequent treatments and absorption of active ingredients.
Step-by-step explanation:
Microdermabrasion is a skin care procedure that involves the physical exfoliation of the top layer of skin using a specialized device. It's commonly performed as a part of a facial treatment sequence. The correct phase of a facial treatment during which microdermabrasion is performed is the treat phase. This phase is designed to address specific skin issues and is the point in the facial when more aggressive treatments, such as microdermabrasion, are employed. The purpose of this procedure is to remove dead skin cells, promote cell regeneration, and improve skin texture and appearance.
During a typical facial, the progression typically involves cleansing, exfoliating, extracting (if necessary), treating—which is where microdermabrasion fits in, followed by massaging, masking, and finally balancing and protecting the skin. As a part of the treat phase, microdermabrasion can effectively prepare the skin for the subsequent absorption of active ingredients from serums or masks applied afterwards.
In conclusion, microdermabrasion serves as an important part of the treat phase of a facial and is instrumental in achieving the goals of skin rejuvenation and improvement.
