At-Home LED Light Therapy for Skin Rejuvenation: A 12-Week Clinical Study

September 2, 2025 updated by: Therabody, Inc.

This clinical study explores the effectiveness of an at-home LED light therapy device combined with vibration for improving various signs of skin aging. Over 115 participants aged 35-65 used the Therabody TheraFace Mask Glo device daily for 12 weeks, receiving treatments that alternated between combined LED/vibration therapy and vibration-only sessions.

The treatment protocol involved:

  • 6 days per week: 12-minute sessions with red, red+infrared, and blue LED light plus vibration
  • 1 day per week: 15-minute vibration-only sessions

Researchers measured improvements across multiple skin concerns including:

  • Fine lines and wrinkles
  • Skin firmness and contour
  • Dark spots and uneven skin tone
  • Skin radiance and texture
  • Sagging skin

Assessment methods included expert clinical evaluations, participant self-reports, and advanced VISIA-CR imaging technology to objectively measure changes in skin quality. This comprehensive approach allowed researchers to evaluate both visible improvements and participants' satisfaction with the treatment.

LED light therapy has gained significant popularity in recent years as a non-invasive approach to skin rejuvenation. Different wavelengths target specific skin concerns:

  • Red light (633nm) may stimulate collagen production
  • Blue light (415nm) may have antibacterial properties
  • Infrared light may promote tissue repair

This study is particularly important because it examines an at-home device, making professional-grade treatments more accessible to consumers. The inclusion of vibration therapy may enhance results by potentially improving circulation and product absorption.

For individuals considering light therapy treatments, this research provides valuable insights into:

  • The commitment required (daily use for 12 weeks)
  • Realistic expectations for results
  • The importance of consistent sun protection during treatment

While LED therapy shows promise for various skin concerns, it's important to consult with a dermatologist before beginning any new treatment regimen, especially for those with sensitive skin or existing skin conditions. Future research might explore longer-term effects, combination with other treatments, and benefits for specific skin types or conditions.

This study represents an important step in validating at-home cosmetic devices, helping consumers make informed decisions about their skincare investments. As the demand for effective, non-invasive anti-aging solutions grows, rigorous clinical testing becomes increasingly valuable for separating truly beneficial technologies from marketing hype.
