Meet Dr. Viv Chen: A Journey from Conventional Medicine to Root Cause Healing
Dr. Chen practiced as a conventional medical doctor for over 15 years before her world changed. Her daughter was hospitalized shortly after birth with mysterious symptoms no one could explain. It was through her own research that Dr. Chen discovered the power of addressing environmental toxins—something she had never been taught in medical school.
Through that journey, she also uncovered the reasons behind her own chronic fatigue, brain fog, and acne. That path led her to discover therapies that support the body at the cellular level—including red light therapy.
What Is Red Light Therapy?
Red light therapy (also known as low-level laser therapy or photobiomodulation) uses low levels of red light and near-infrared light to stimulate cellular function and healing. Red light is delivered through LED devices or low-level lasersand penetrates the skin to enhance energy production (by stimulating adenosine triphosphate (ATP)), reduce oxidative stress, and improve blood circulation.
Benefits of Red Light Therapy
Here are the most clinically studied and user-reported benefits of red light therapy:
1. Skin Health & Rejuvenation
Red light therapy stimulates collagen production, helping reduce the appearance of fine lines, wrinkles, and skin concerns like acne, rosacea, and eczema. It also supports wound healing and improves skin tone and texture.
2. Pain Relief & Reduced Inflammation
Whether you’re dealing with chronic pain, joint pain, muscle soreness, or rheumatoid arthritis, red light therapy helps increase blood flow to affected areas, reduce inflammation, and support tissue regeneration—all without drugs or invasive treatments.
 3. Hair Growth
Studies have shown that red light can stimulate hair follicles in people experiencing androgenic alopecia (pattern hair loss), supporting hair regrowth through increased circulation and enhanced cellular processes.
 4. Mood & Energy Support
Red light therapy has been shown to improve sleep, boost mood, and enhance mental clarity by supporting cell functionin the brain and improving mitochondrial health.
At-Home Use vs. In-Office Treatments
Thanks to portable devices and red light face masks, many people are using at-home red light therapy as part of their daily skin care and wellness routine. These at-home devices are a non-invasive treatment option that can provide results over time with consistent use.
For best results, make sure to:
Choose a device with specific wavelengths of light (typically between 630–850nm)
Use it consistently (several sessions per week)
Follow manufacturer guidelines for treatment time and distance from skin
If you’re looking for deeper, targeted care or are addressing serious medical conditions, you may benefit from in-office treatments guided by a board-certified dermatologist or healthcare provider.
What About Side Effects and Risks?
Red light therapy is generally well-tolerated with minimal side effects. Unlike UV light or tanning beds, red light does not damage skin or increase the risk of skin cancer. However, if you have sensitive skin, photosensitivity, or any specific health conditions, consult your healthcare professional before starting.
Some potential risks include:
Mild skin irritation with overuse
Eye sensitivity (always wear protective goggles)
Interference with certain light-sensitive medications
Is It Really Backed by Science?
Yes. Multiple clinical studies, systematic reviews, and research from institutions like the Cleveland Clinic have shown significant improvement in skin conditions, oral mucositis, carpal tunnel syndrome, muscle pain, and more when using red light therapy correctly.
Final Thoughts
Whether you’re seeking effective treatment for skin issues, looking to support cellular function, or simply want youthful-looking skin with fewer side effects, red light therapy is a powerful, non-invasive treatment option worth exploring.
If you’re just beginning your journey or looking for a reliable at-home device, be sure to do your research and talk to a trusted healthcare provider about what will work best for you.
