What is LED Light Therapy?
A light therapy resembling fluorescent light is often used as a treatment for acne. This acne treatment is administered by placing the patient at an appropriate distance from the lights, without any barrier between the patient and the lights.
This device supposedly uses wavelength-specific phototherapy to improve the patient’s condition. The dosage is determined based on factors such as the frequency, duration, color and intensity of the light.
Although most dermatologists and specialists in the field of light therapy consider light therapy as a very good cure for acne, it has been reported that this treatment may not be as harmless as it has been projected.
Dermatologists have noted that the best results are obtained after a course of treatment that lasts two to four weeks and treatments with this light are administered every day for two to four weeks.
It is said that the treatments with this light therapy stimulate the production of new cells in the skin and result in the purging of old skin cells and bacteria. Be that as it may, it has also been reported that those who are undergoing these acne treatment sessions may have suffered severe damage to their eyes and skin.
Among the side effects (which are, as a matter of fact, the main problem with the use of this light) reported, are burns of the retina, cataracts, conjunctivitis, and skin burns.
What to Expect from LED Light Therapy
LED light therapy is a form of light therapy where LEDs are used instead of lasers. While, lasers are more suited for skin treatment because of their great range of wavelengths, LEDs are more suited for the treatment of the body tissues because their penetration is limited only to the surface layers.
Both light therapy and phototherapy are used for skin health. Both deliver light in order to improve or reduce the symptoms caused by numerous skin conditions, such as psoriasis, eczema, acne, rosacea and many others.
Specific light wavelengths or combinations of wavelengths of light have been shown to stimulate the production of specific chemicals in the skin. These chemicals work to affect any of the following positive changes: deactivate the cells that make the skin produce too much oil, increase cells in the skin that help fight infection, reduce inflammation, promote growth of healthy skin cells.
The best effect depends on the wavelength and intensity of the light that is used. Blue-green light relieves itching, red light is beneficial for Rosacea, green light is good for acne.
An LED light therapy device delivers light – usually red or blue-green- in a particular wavelength, intensity and time interval that is needed.
Phototherapy and LED light therapy device are applied either directly on the skin or close to the skin using special goggles made of polycarbonate and polyethylene.
Dangers of Light Therapy? Side Effects to Consider
Low-level Light Therapy, also known as LLLT, has entered the health scene as an alternative treatment for a variety of ailments, including hair loss. But this non-traditional treatment has a dark ethical side.
LLLT is also known as Red Light Therapy, and you may have been drawn to it for its effectiveness in treating acne and psoriasis. The treatment does not directly interact with DNA, which makes it a safer light therapy.
Opting for a safer alternative is good. There is a catch: LLLT’s safety does not mean that it is impossible to overdose on the treatment. Overexposing your skin will actually give it a damaging energy burst, which can easily lead to “light burn damage.”
Side effects will depend on how long you overexpose your skin, but a possibility is that it will cause inflammation, pain, and sensitivity. The most excessive side effect is actually the worst, which is a longer-term sensitivity to light.
Too much of a good thing can be bad. Moderate, controlled use can be helpful, but if you do suspect that you have light burn damage after overexposing your skin, discontinue use and consult your doctor or dermatologist.
