Hyaluronic Acid Delivery: CO2 Laser Versus Thulium Laser Treatment

In Vivo Visualisation of Hyaluronic Acid After CO2 Laser Compared to Thulium Laser Treatment

• Weakly crossed-linked hyaluronic acid (HA) can be delivered through multiple injections into the dermal and subnormal layer to improve skin quality. However, this treatment comes with multiple bumps for several days.
• Alternatively, HA can be delivered after CO2 laser or thulium laser pretreatment. As microscopic analysis after this treatment is limited, the object of the present study is to investigate the morphological cellular changes after CO2 laser and thulium laser delivered HA into human skin.

Inclusion Criteria:

- healthy male and female patients
