Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • Enlarged pores are caused by multifactorial factors such as sex, genetics, aging, etc.
  • The gold of the treatment is to recollagenesis of the dermis and resurfacing of the epidermis.
  • Modalities that have been proved on their efficacy for enlarged pores treatment included topical retinoic acid, chemical peeling, intense pulsed light, radiofrequency device, laser such as Q-switched and Long Pulsed Neodymium-Doped Yttrium-Aluminum-Garnet (Nd:YAG) 1,064nm, Long pulse duration pulsed dye laser 595nm, etc.
  • Er:YAG laser is an ablative laser which creates both recollagenesis and resurfacing. It ha been proved to be safe and effective in the treatment of atrophic acne scar.
  • However, the efficacy of this laser for enlarged treatment has not yet been established.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The efficacy of Er:YAG laser in the treatment of enlarged pores (measurement of skin texture using UVA-light video camera)
Time Frame: 1 month after 4 treatments
measurement of skin texture using UVA-light video camera
1 month after 4 treatments

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
