What is (LHE) Light, Heat, Energy?
|
|
|
LHE Technology, Light & Heat Energy, first developed by Radiancy in 1998, is the singular most efficient form of phototherapy in medical and aesthetic field today. Its inherent safety and flexibility enables its use in a wide variety of applications. LHE is currently being employed for Hair Removal, Acne Clearance, Skin Rejuvenation and Psoriasis, with more applications on the horizon.

Traditional Phototherapy

Phototherapy, also known as Light Treatment, entails the use of Light to heal or treat a medical or aesthetic condition, Photo meaning light and therapy meaning to treat. Phototherapy has been used to treat such diverse conditions as newborn jaundice, psoriasis and acne. The medical use of phototherapy dates back to ancient times when Greeks built solarium cities in high mountains to harness ultra-violet light for healing tuberculosis. In more recent times, red light was used to suppress the effects of the smallpox virus. Since the 1920s, phototherapy has been extensively used in the treatment of many photoresponsive skin diseases such as psoriasis. Modern day phototherapy balances wavelengths, intensity of light and exposure duration among other parameters to tailor treatment to specific needs and conditions.

| In the early 80's a new method of light-based therapy termed selective photothermolysis was developed. The word photothermolysis is from three Greek words; photo meaning light, thermo meaning heat, and lysis- destruction |
|
| The theory of selective photothermolysis maintains that by optimizing certain application parameters, the practitioner can target a specific chromophore for destruction, while minimizing the effect on surrounding tissue. |

LHE Phototherapy - The Next Generation
|
|
|
LHE advances the principles of selective photothermolysis by utilizing the dual energy pathways of light and heat.
|
|
| Most light-based technologies like laser and Intense Pulsed Light (IPL) rely on light energy to effect clinical changes while they filter out the subsequent heat. Because they filter out the heat instead of using it, they require very high fluences for clinical efficacy, high fluences that require skin cooling techniques to protect the client from burns. |
|
|
In order to best utilize the heat, lower the fluence and gain the greatest benefit from the light/heat relationship, Radiancy engineers developed patented internal filters that protect the skin, along with innovative algorithms that take full advantage of the skins thermal absorption characteristics. These innovations create the exact balance of light and heat necessary to achieve clinical efficacy in a variety of clinical applications.
|
|
| Because it enables very low fluences, LHE’s natural fusion of light and heat creates a far more efficient photo thermal technique. The addition of direct heat increases overall effectiveness and lowers fluence to ultra safe levels. |
|
|
Lowering fluence allows us to eliminate the need for skin cooling techniques, simplify the treatment process and minimize risk of harmful side effects, making it safer, easier and more cost effective.

|
|
LHE also enables greater flexibility by utilizing a variety of Light Unit Assemblies (LUA) that emit different spectral distributions for specific clinical applications.
