Photodynamic therapy (PDT) is a medical treatment that uses a light-sensitive drug and a special kind of light to kill abnormal cells, such as some cancer cells or those that cause severe acne or actinic keratoses. It's a targeted approach, but not without its considerations.

Red light therapy is NOT a hoax; it's a scientifically validated therapeutic modality known as photobiomodulation.

LED light therapy uses specific, clinically validated wavelengths of light to penetrate the skin and energize your cells. This process can kickstart collagen production, calm inflammation, and accelerate repair, leading to visibly healthier, more youthful-looking skin over time.

Low-level light therapy, or photobiomodulation, is clinically proven to reduce pain, ease inflammation, speed up tissue repair, and rejuvenate skin. It's a non-invasive treatment using specific light wavelengths to stimulate cellular healing processes effectively across various medical fields.

Technically, yes, you can assemble LEDs into a panel. However, achieving the correct therapeutic wavelengths, sufficient and even irradiance, and ensuring electrical safety without professional components and testing is extremely difficult and potentially hazardous. It's generally not recommended.

Look for clinically relevant wavelengths (Red 660nm & NIR 850nm are common), sufficient irradiance (power density, ideally >50 mW/cm² at the surface), good coverage area, flexible/comfortable fit, safety certifications (like FDA, CE), and a reputable manufacturer.

Absolutely not. Red light therapy uses specific red and near-infrared wavelengths that do not stimulate melanin production, the pigment responsible for tanning. Unlike UV light from the sun or tanning beds, RLT won't tan or burn your skin.

For targeted facial treatment, LED masks or handheld/portable devices offering specific red (around 630-660nm) and potentially near-infrared (around 830-850nm) wavelengths are generally best.

Infrared light therapy uses longer, invisible wavelengths (800-1200nm) to penetrate deeper into tissues. It primarily targets muscle recovery, joint pain, inflammation reduction, and improved circulation by stimulating cellular energy production.

While generally considered safe for the skin, direct, prolonged exposure of your eyes to the bright light from red light therapy devices, especially powerful panels, isn't recommended.
