Comparison of Heat Shock Protein 70 Expression in Response to Different Non-Ablative Lasers: An Study.

The objective of our study was to compare the extent and timing of heat shock protein 70 (HSP70) expression following non-ablative fractional laser (NAFL) Er:Glass as well as Nd:YAG and alexandrite laser systems. The role of HSP70 has been established in wound healing. Reports indicate that HSP70 expression increases after skin laser interventions.
