Outcome Measures

Primary Outcomes (1)

  • Colorimetry

    The skin tone dissimilarity (expressed as ΔE) at treated and adjacent areas measured with digital calorimetry. The ΔE value derives from the differences in the International Commission on Illumination L\*a\*b\* (CIELAB) color space. It is a structured approach to quantifying color differences, with specific intervals indicating varying levels of perceptibility with different intensities of pigmentation: * 0 \< ∆E \< 1 - the difference is unnoticeable * 1 \< ∆E\< 2 - the difference is only noticed by an experienced observer (mild), * 2 \< ∆E \< 3.5 - the difference is also noticed by an inexperienced observer (light), * 3.5 \< ∆E \< 5 - the difference is noticeable (moderate), * 5 \< ∆E - gives the impression that these are two different colors (intense) In all sessions, patients will be submitted to colorimetric analysis. The ∆E is the skin color difference between the treated and adjacent areas.

Arm 3

PLACEBO COMPARATOR

Control vehicle (cold cream)

Drug: cold cream

Interventions

Nd: YAG 1064 nm short pulse laser (5 nanoseconds), 4 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Smart, a Q-Switch Laser produced by Medical San (Lajeado, RS, Brazil).

Also known as: Arm 1
Arm 1: ND YAG laser: 1064 nm short pulse (nanoseconds) - Omer Smart

Nd: YAG1064 nm ultra-short pulse laser (400 picoseconds), 2 to 10 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for 6 visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Premium, a picolaser produced by Medical San (Lajeado, RS, Brazil).

Arm 2: ND YAG laser: 1064 nm ultra- short pulse (picoseconds) - omer Premium

The control vehicle is a cold cream, supplied by HERVA'S manipulation pharmacy. The composition of cold cream will be beeswax, acetyl palmitate, BHA, cetearyl alcohol, propylparaben, and water. This topical agent will be applied to patients daily throughout the treatment period. It is scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days.
