The goal of this observational registry study is to characterize postoperative recovery outcomes in adult patients receiving standard-of-care perioperative light therapy using an FDA-cleared photobiomodulation device as part of routine clinical practice. The study aims to describe changes in patient-reported and clinician-assessed recovery measures following elective surgical procedures.

The main questions this registry aims to answer are:

1. How do patient-reported recovery outcomes, including pain, satisfaction, and perceived improvement, change over the postoperative period?
2. How do clinician-assessed indicators of recovery, such as swelling and bruising, change over time following surgery?

This study does not include a randomized comparison group. Outcomes will be described longitudinally within participants based on data collected during routine care.

Participants will:

1. Receive perioperative light therapy as part of standard clinical care, per their treating clinician
2. Complete patient-reported outcome questionnaires at defined postoperative time points
3. Undergo standardized clinical photography and routine clinical assessments as part of usual follow-up

Inclusion Criteria:

• Adults aged 18 years or older undergoing elective plastic surgery (facial or body procedures) at a participating plastic surgery practice where the ELIXIR MD™ device is used as part of standard perioperative care.
• Able to provide informed consent and complete brief patient-reported questionnaires.

Exclusion Criteria:

• Pregnancy.
• Basal cell carcinoma, thyroid disorders, or malignant tumors.
• History of photosensitive skin disease or photosensitivity.
• Epilepsy or seizure disorders.
• Recent use of photosensitizing medications, including isotretinoin within the past 6 months; tetracyclines or ciprofloxacin within the past 5 days; chlorpromazine within the past 8 days; methotrexate within the past 3 days; or amiodarone, per physician discretion.

The study population consists of adult patients aged 18 years or older undergoing elective plastic surgery procedures (facial or body) at participating plastic surgery practices. All participants receive perioperative care in which the ELIXIR MD™ photobiomodulation device may be used as part of standard clinical practice, at the discretion of the treating surgeon. The registry enrolls patients across a range of procedure types and skin phototypes and collects de-identified patient-reported and clinical recovery data during routine perioperative follow-up.

De-identified individual participant data (IPD) generated in this observational registry, including patient-reported outcomes, procedure characteristics, and perioperative recovery assessments collected during routine clinical care. No direct identifiers will be shared.

Beginning after publication of the primary study results and available upon reasonable request, with no predefined end date.

Access to de-identified individual participant data (IPD) and supporting study documents will be limited to qualified researchers with a legitimate scientific purpose. Researchers may request access by submitting a written proposal to the sponsor describing the research question, analysis plan, and intended use of the data.

Requests will be reviewed by the sponsor for scientific merit, feasibility, and compliance with ethical and privacy requirements. Approved researchers will be granted access only to de-identified participant-level data relevant to the approved proposal. No protected health information (PHI) will be shared.

Data access will be provided through secure data transfer or controlled access methods, subject to execution of a data use agreement.
