What is LED light therapy and what are the benefits?

The visible spectrum has different wavelengths, each corresponding to a different color, and penetrates to different depths of the skin. It is thought that LED light will have different effects depending on the level of skin it penetrates.

The most commonly used frequencies in LED light therapy are red and blue wavelengths, which are easily absorbed by the skin and do not contain harmful UV rays. Red light is used to treat the outermost layer of the skin, also known as the epidermis. It is thought that when this layer of skin absorbs infrared light, the fibroblasts responsible for producing collagen are stimulated. The increased production of collagen can make the skin appear smoother, thereby reducing the appearance of fine lines and wrinkles.

On the other hand, blue light targets the oil glands located deep in the skin. By reducing the amount of oil these glands produce, the skin becomes drier, which reduces acne breakouts.

In most cases, LED light requires multiple treatments, with a typical treatment time of up to 30 minutes. Depending on the device used, you can lie directly under the light source, or you can use a more targeted device, such as an LED mask or massage stick, directly on the area to be treated. While LED light therapy can be used anywhere on the body, it is most commonly used to treat facial damage caused by sunlight and other factors.

LED light therapy is non-invasive, so there is little risk and no need for hospitalization. It can be used on all skin types without burning the skin. Also, LED light therapy does not cause pain. However, in rare cases, treatment of an area, such as an active rash or the use of isotretinoin, may not be recommended.

While the skin may improve significantly after LED light therapy, follow-up treatment or maintenance is required. If you are considering LED light therapy, the first step is to consult with a board-certified plastic surgeon who also has experience with LED light therapy devices. Be sure to do your homework and research the credentials of an orthopedic surgeon. While this doesn't guarantee results, it's the best way to make sure you're happy with the results.

Photodynamic therapy (PDT) is a skin treatment based on medical theory. It combines LED light sources and photosensitive cosmetics or drugs to treat various skin problems. LED phototherapy masks have been shown to be effective in treating many aspects of skin aging. Multiple studies have shown its improvements in fine wrinkles, mottled pigmentation, rough and light touch.

In addition, LED photodynamic therapy (PDT) has been widely used as a cosmetic technique in skin care. Photon energy has a positive effect on skin cells. It accelerates cell growth, improves collagen and elastin production, promotes micro blood circulation, and improves overall skin condition.
