Scientists and dermatologists are continually studying and developing treatments for skin conditions and ways to achieve healthier skin. Red light therapy, discovered in the ’60s, is one of the noninvasive treatments dermatologists are using to improve their clients’ skin’s appearance and treat some issues they face.

Red light therapy has gained popularity in recent years, with many devices now available for people who want to do the treatment at home.

So, what exactly is it?

The treatment — also known as red LED light therapy, low-level light therapy (LLLT), photobiomodulation, and cold laser therapy — involves exposing the skin to low-wavelength red light in order to address a number of skin concerns.

A 2013 study said red light doesn’t produce heat due to its low wavelength. According to 2017 research, it is extinguished some 4 to 5 millimeters beneath the surface of the skin.

Exposure to red light may result in the strengthening of mitochondria, leading to cells functioning more effectively. This, in turn, can result in enhanced skin rejuvenation.

According to research, red light therapy has been shown to reduce inflammation, stimulate collagen production, and improve blood circulation. 

Due to this, it is now used to heal wounds, promote hair growth, and address concerns such as wrinkles, scars, acne, and psoriasis.

People using this therapy, particularly those with significant signs of aging who want to minimize fine lines and wrinkles, may see improvements in their skin after several sessions.

This is a recommended treatment for people suffering from skin conditions who can’t find the right skincare solutions. But before scheduling your therapy appointment, make sure to consult with your doctor to ensure that red light therapy is suitable for your skin type. 

Many places offer red light therapy, such as tanning salons and day spas, but there are also options to purchase FDA-approved red light therapy devices online and try this treatment in the comfort of your own home.
