In this blog, we will discuss the process of LED light therapy and how it works on the skin.

LED light therapy and red light skin treatments are forms of Phototherapy. Medical treatments and therapies involving light like sunlight, light-emitting diodes, fluorescent light bulbs, etc., are referred to as Phototherapy. For different skin conditions and ailments, there are various types of Phototherapy.

Now, let’s dig deeper into the history of Phototherapy.

History of Phototherapy

The use of Phototherapy for the treatment of skin-related disorders can be traced back to 3,500 years ago. Ancient Egyptians and Indians have been using Phototherapy to treat skin conditions like vitiligo.

It was Neils Ryberg Finsen who first used an artificial source of light to treat skin conditions. He is regarded as the father of modern Phototherapy and credited for introducing the technique to the masses. He used sunlight and ultraviolet radiation to treat lupus vulgaris. Eventually, the technique was refined and developed into what is known today. Now, many of the largest tanning salon chains offer a wide range of LED light skin therapies and treatments.

Types of Phototherapy used for skin ailments:

Broadband UVB: It is also known as BBUVB or broadband UVB therapy.  Full-spectrum of ultraviolet-B radiation is used in BBUVB therapy. This type of light therapy is used for the treatment of psoriasis and eczema.

Narrowband UVB: In this particular light therapy, a small part of UVB radiation is used for the treatment. Compared to broadband UVB, narrowband UVB treatment is intense. Dermatologists often use narrowband UVB therapy for the treatment of skin conditions.

PUVA: PUVA is also known as Psolaren ultraviolet-A therapy. In this therapy, the UVA light is combined with a chemical called psoralen. Psolaren is a plant-based chemical that can be taken as a pill or applied to the skin. Psolaren makes the skin sensitive to the light that is to be used for the treatment. Since PUVA involves the use of more intense light, it has many side effects. PUVA is only used when other light therapies fail to give the desired result.

The effects of light therapy are not permanent, and thus, one must undergo repeated sessions to maintain the treatment’s effect.

Phototherapy is safe when used for skin conditions. However, one may experience redness, itchiness, blisters, and dry skin. These side-effects only last for a couple of days and vanish on their own.
