Micro-Coring® for the Treatment of Skin Laxity of the Knees

Enrolling by invitation · Not applicable

Conditions studied: Body, Knees

In brief

Early, informal clinical experience suggests that Micro-Coring may help improve skin quality in certain body areas, such as the knees. However, this body region has not yet been formally studied. Additional clinical evaluation is needed to better understand healing, potential side effects, patient experience, ease of use, and optimal treatment settings for body sites. This is especially important because body skin differs from facial skin in thickness, blood supply, movement, and mechanical stress, which may affect both safety and healing outcomes.
