The biggest difference between LED light and traditional light is that LED light uses diodes which contain electrons and move in a semiconductor generating light. This means that LED light is not hot unlike the light created by lightbulbs and is safe to use on your skin.
When we talk about the used in the medical and aesthetic world then we actually have infrared LEDs. If you are well aware of the physics classes at school, you may know that infrared light is actually a radiation in the electromagnetic spectrum that can not be seen by the naked eye.
Infrared therapy actually combines visible red or blue light (each with their own therapeutic effects) with healing infrared light. Research has shown that a number of skin conditions, such as rosacea, can be cured or relieved by regular and repeated treatment.
What kind of LED for your skin?
As with the laser therapies, different types of leds are also used depending on which condition is being treated. For example, blue light has antibacterial properties and is therefore approved for acne therapy. Red light is then known as anti-inflammatory and helps repair damaged skin. It also helps keep sebum secretion under control.
Therefore, for the treatment of rosacea, red light is usually preferred. The treatment must be carried out by specialists. They will adjust the intensity of light so that an already damaged and sensitive skin can not be tested further.
Red LED light also has other positive effects. It has been demonstrated that it regularly stimulates the production of collagen and elastin. These are the proteins that keep our skin smooth and firm. Skin cells that were damaged by the sun or other external factors and the damage caused by free radicals are restored by the red led light.
The difference between LEDs and lasers
The light rays emitted by lasers are highly concentrated and are designed to treat small areas intensively. They generate heat in the underlying tissues that become inflamed and in this way force the skin to renew itself. Other lasers destroy blood vessels so they are no longer visible.
Laser treatments often require some form of anesthesia, and the inflammation that causes them causes your skin a long recovery period. If used improperly, they can cause injuries and scars.
Led therapy does not have these problems because it is much less concentrated and intensive than lasers. Leds also treat a much larger skin surface than lasers, and although they actually penetrate the skin, they do not cause warming or inflammation of the skin tissues.
