Treatment of Melasma With Yellow Light Compared to Tranexamic Acid

October 17, 2024 updated by: Christiane Pavani, University of Nove de Julho

Photobiomodulation With Yellow Light in the Treatment of Melasma: Clinical Trial, Randomized, Controlled, Double Blind.

Photobiomodulation (PBM) has been suggested as an alternative treatment for Melasma, showed by the in vitro data, inhibition of the tyrosinase enzyme and reduction in the pigment content by autophagy. This treatment compares with tranexamic acid, where it acts on similar pathways of melanogenesis. A total of 54 female participants, phototype scale Fitzpatrick ll - lV will be recruited which will be distributed among two groups: Light + placebo Home Care cosmetic product and Light sham + Home Care cosmetic product with tranexamic acid. The treatments will consist of 90 days, with application of photobiomodulation (PBM) once a week and application of the cosmetic product twice a day.

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

This is a controled, randomized, double blind, two arms clinical trial. The main objective of this study is to evaluate the effect of photobiomodulation with amber light in the treatment of Melasma compared to the effect of tranexamic acid. The sample will be divided into 2 groups: Group 1 will receive PBM with amber Light Emitting Diode (LED) (DMC E-Light ABR), 20 J/cm² and placebo topical cosmetic for use in home care; Group 2 will receive PBM sham and topical cosmetic containing 5% liposomal tranexamic acid for use in home care. A total of 54 women with facial Melasma, aged 35 to 50 will be included. The treatments will consist of 12 sessions, once a week for 3 months. The severity of Melasma will be evaluated through the Melasma Area and Severity Index (MASI index), the pigmentation of the epidermis will be evaluated by corneomelametry, photographic records and the quality of life questionnaire (MELASQoL-PB) will also be made.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Photobiomodulation (PBM) with placebo cosmetic treatment.
Participants will receive the intervention with PBM using amber light (DMC E-Light ABR), 20 J/cm² and will also receive a product for daily home topical use containing only the cosmetic base without active.
Device: Photobiomodulation group
Participants will have their face sanitized with micellar water (a cosmetic product for cleaning and makeup remover), followed by cleaning with soap. Then, the eyes will be protected with gauze, proper glasses and a black towel on top, a headset with relaxation music will also be placed and then the face will receive the treatment with yellow light. After the session the face will receive sunscreen. A placebo cosmetic will be given to the participant to be applied twice a day and daily sunscreen.
Active Comparator: Photobiomodulation (PBM) sham with 5% liposomal tranexamic acid cosmetic product
Participants will receive the simulated intervention with PBM using amber light (DMC E-Light ABR) and will also receive a product for topical home use containing 5% liposomal tranexamic acid.
Other: Group control (Tranexamic acid)
Participants will have their face sanitized with micellar water. Then, the eyes will be protected with gauze, proper glasses and a black towel on top, a headset with relaxation music will also be placed and then the face will receive the treatment with yellow light sham. The person responsible for applying the PBM will simulate the irradiations by positioning the device in the same places described for the PBM group, however, the equipment will be kept off. After the session the face will receive sunscreen. Will be delivered to patients, liposomal tranexamic acid with use 2 x a day home care and daily sunscreen.
