Inclusion criteria

Inclusion criteria: Postpartum women aged 18 or older; first-time mothers with full-term pregnancy; live fetus; good physical condition, vaginal delivery outcome, with perineal trauma; with sutures; no infection

Exclusion criteria

Exclusion criteria: Postpartum women with significant obstetric complications; use of products in the vulvoperineal area that involve the healing process; women with papillomavirus; women with active perineal cancer; women with perineal lesions without a diagnosis; history of gynecological or perineal cancer; use of photosensitizing medication

Design outcomes

Primary

Measure	Time frame
Evaluate the action of irradiation with photobiomodulation through the light-emitting diode plate in the healing process of first- or second-degree perineal trauma after vaginal delivery	—

Secondary

Measure	Time frame
Compare the evolution of the perineal healing process, assessed using the perineal healing scale between the intervention and control groups;It is expected to identify the opinion of the postpartum women regarding the intervention through the satisfaction scale;Assess and compare the perineal pain reported by postpartum women subjected to the two study groups, in this case, the intervention and control groups, using the numerical pain scale	—
