What type of treatment involves mechanical stimulation of the skin?

Mechanical stimulation of the skin refers to treatments that involve physical manipulation, movement, or touch that impacts the skin's surface and underlying tissues. Massage therapy fits this description perfectly, as it utilizes hands-on techniques to knead, stroke, or apply pressure to the skin and muscles, enhancing blood circulation, promoting lymphatic drainage, and relaxing the muscles.

In contrast, the other options do not primarily focus on mechanical stimulation. Laser treatment utilizes focused light energy to target specific structures within the skin without direct contact. A Hydrafacial is a multi-step treatment that includes cleansing, exfoliation, and infusion of serums but relies more on suction and liquid application rather than mechanical stimulation. Lastly, a chemical peel involves the application of chemical solutions to exfoliate and improve the skin's appearance, focusing on the chemical action rather than physical manipulation.

Understanding these distinctions highlights why massage therapy is categorized as a treatment that involves mechanical stimulation of the skin.
