Benefit deriving from the use of light is known since ancient time, but, only in the last decades of twentieth century, we witnessed the rapid expansion of knowledge and techniques. Light-emitted diode (LED)-based devices represent the emerging and safest tool for the treatment of many conditions such as skin inflammatory conditions, aging, and disorders linked to hair growth. The present work reviews the current knowledge about LED-based therapeutic approaches in different skin and hair disorders. LED therapy represents the emerging and safest tool for the treatment of many conditions such as skin inflammatory conditions, aging, and disorders linked to hair growth. The use of LED in the treatment of such conditions has now entered common practice among dermatologists.

LED light therapy is a popular noninvasive skin treatment for acne, sun damage, wounds, and other skin problems.
People can choose to have LED light therapy at a dermatologist’s office or to use a device at home.
The treatment uses varying wavelengths of light to trigger the skin’s natural healing processes to repair the skin. Several treatments are necessary to see results.
In this article, we explore how LED light therapy works and who might be a good candidate. We also cover the possible side effects.
LED stands for light-emitting diode. These lights have been in use since the 1960s, but people have only recently begun to use them as a skin treatment.
NASA originally developedTrusted Source LED lights for plant growth experiments in space.
However, since then, LEDs have shown promising results in wound healing and human tissue growth.
Different wavelengths of light in LED lights, including blue and red, penetrate the skin at different depths. This penetration may trigger biological processes that help the skin rejuvenate and heal.
