Final answer:
The Mask step of the microdermabrasion treatment is the start of the balance phase.
Step-by-step explanation:
Microdermabrasion is a non-invasive cosmetic procedure that involves the mechanical exfoliation of the outer layer of skin. It is commonly used to improve the texture and appearance of the skin, addressing issues such as fine lines, wrinkles, sun damage, acne scars, and hyperpigmentation.
The Mask step of the microdermabrasion treatment is the start of the balance phase. The balance phase focuses on restoring the skin's pH level and hydration after exfoliation. In this phase, a mask is applied to the skin to soothe and nourish it.
