Ablative fractional laser (AFL) generates microchannels in skin surrounded by a zone of thermally altered tissue, termed the coagulation zone (CZ). The thickness of CZ varies according to applied wavelength and laser settings. It is well‐known that AFL channels facilitate uptake of topically applied compounds, but the importance of CZ is unknown.
