Outcome Measures

Primary Outcomes (1)

  • Pain-Anesthetic effect of AFL

    Pain evaluation of the injected filler, with a VAS (0 to 10)

    immediately after the intervention/procedure

Study Arms (2)

Intervention group

EXPERIMENTAL

This test region (right or left cheek) will be pretreated with a fractional carbon dioxide laser (ablative fractional laser; AFL) with a 100 μm spot at 5% density and a pulse energy of 2.5 mJ/microbeam, single pulse at t0 in a operator- and subject- blinded fashion. A lidocaine and tetracaine mixture cream will be applied at each cheek at t1.Ten minutes after cream application (incubation time), the facial filler injections will be performed. Interventions: AFL Device: AFL Drug: anesthetic mixture cream

Procedure: Facial filler injection

Control

PLACEBO COMPARATOR

A pass with the same fractional carbon dioxide laser with a 100 μm spot at 5% density and a pulse energy of 2.5 mJ/microbeam, single pulse will be given at the area right adjacent to the test region on the other to the intervention cheek ("sham AFL") at t0 in a operator- and subject-blinded fashion. A lidocaine and tetracaine mixture cream will be applied at each cheek at t1.Ten minutes after cream application (incubation time), the facial filler injections will be performed. Interventions: sham AFL Device: sham AFL Drug: anesthetic mixture cream

Procedure: Facial filler injection

Interventions

Hyaluronic acid will be injected on the cheek, based on the aesthetic evaluation of the face.

Also known as: hyaluronic acid injection
