What is considered an advanced method of exfoliation?

A lancet is considered an advanced method of exfoliation because it involves precise and controlled skin intervention, typically used to treat specific skin conditions by incising the skin surface. This technique allows for deeper and more targeted exfoliation compared to other methods, which primarily focus on surface exfoliation.

Microdermabrasion, chemical peels, and facial scrubs are also effective exfoliation methods but typically address the skin's outermost layer rather than providing deeper or more clinical interventions. While these methods can enhance skin texture and appearance, they do not involve the same level of control or specificity as using a lancet, which requires a certain skill level and knowledge about human anatomy and skin health.
