Skin needling for creating microchannels has minimal discomfort as the a maximum depth is below 1.5 mm. It can feel a bit scratchy, but your practitioner will vary the settings during treatment areas to maximise comfort.
For needling deeper than 1.5 mm your practitioner will apply a topical anaesthetic to minimise discomfort. For certain treatments a local anaesthetic block may be injected to ensure maximum comfort.
