Does full-face laser hair reduction affect facial hair on the eyebrows or hairline?
Full-face laser hair reduction does not affect the eyebrows or scalp hairline because the dermatologist physically masks both regions before each pulse and confines treatment to the cheek, lateral forehead, perioral, and submandibular zones. The four-wavelength diode laser (FDA K191321 cleared) is delivered through a controlled-aperture sapphire applicator that the physician steers manually, not on a template, which is the reason dermatologist-performed treatment matters on the face. Patients with bushy eyebrows or a low hairline can be treated safely; the dermatologist marks no-go zones on the skin before each session and re-marks at every follow-up.
