Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • MASI (Melasma Area and Severity Index)

    Determines the affected area and the severity of Melasma, through visual analysis of the affected site and attribution of scores

    Before treatment (week 0).

  • MASI (Melasma Area and Severity Index)

    Determines the affected area and the severity of Melasma, through visual analysis of the affected site and attribution of scores

    Half treatment (Week 6)

  • MASI (Melasma Area and Severity Index)

    Determines the affected area and the severity of Melasma, through visual analysis of the affected site and attribution of scores

    After the treatments (week 12).

Secondary Outcomes (5)

  • Corneomelametry

    Before (week 0), at half (week 6) and after treatment (week 12).

  • Photography

    Before (week 0), at half (week 6) and after treatment (week 12).

  • Final global diagnosis of the skin.

    Before (week 0), at half (week 6) and after treatment (week 12).

  • The MELASQoL questionnaire, (Melasma Quality of Life Scale)

    Before (week 0), at half (week 6) and after treatment (week 12).

  • Adverse Effects

    At half (week 6) and after treatment (week 12).

Study Arms (2)

Photobiomodulation (PBM) with placebo cosmetic treatment.

EXPERIMENTAL

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

ACTIVE COMPARATOR

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)

Interventions

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.

Photobiomodulation (PBM) with placebo cosmetic treatment.

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.

Intervention Model
PARALLEL
Model Details: All participants will receive a skin preparation with enzymatic peeling, for homogeneity in the thickness of the stratum corneum among the participants and to reduce the unwanted reflection of photons. One week after the application of the peeling, the pre-treatment evaluation will be carried out and the participants will receive the intervention related to their treatment group, according to the allocation given by randomization. The area to be treated will be sanitized with Rennova® Beauté Micellar Water for makeup/sunscreen removal. Then, a cleaning foam based on 10% urea from Vivence laboratory will be used and also removed with gauze. After randomization, the study population will be divided into two groups (n=28 per group), wich are: (1) Group A - PBM with yellow LED application + placebo cosmetic treatment Home Care 2x per day, (2) Group B - PBM sham + treatment with 5% liposomal tranexamic acid Home Care cosmetic cream 2x per day.
