LED Light Therapy Technology

We all know about using LED lights to light a room, but did you know LED lights can help treat acne, scarring, wrinkles, and other skin conditions? In the past, patients would attend sessions with a dermatologist to receive LED skin treatment, but nowadays customers can buy an LED face mask for home use.

How Does it Work?

LED therapy works to treat a variety of conditions including:

  • Acne
  • Dermatitis
  • Dull skin
  • Eczema
  • Psoriasis
  • Rosacea
  • Scarring
  • Signs of aging, like wrinkles and age spots
  • Sun damage
  • Wounds
  • Other inflammatory skin conditions

Blue and red light both contribute to LED light therapy. Red light therapy helps treat scarring as well as fine lines and wrinkles. It does this by acting on fibroblasts, the skin cells responsible for collagen production. Collagen refers to the protein that form the majority of connective tissue, helping with healing. Collagen production slows with age, causing wrinkles to appear. By helping to increase collagen production, red light treatments work very effectively on aging skin.

Blue light primarily suppresses the sebaceous glands that produce oil. By reducing oil production, blue light treatments reduce acne. Blue light treatment also helps to treat third-degree burns.

Additionally, green light can treat hyperpigmentation, such as brown spots or freckles, by targeting the melanin-producing cells known as melanocytes.

What is the treatment process like?

Patients seeking LED treatments for skin conditions can attend sessions at a dermatologist’s office. Sessions typically last 20 minutes and patients usually see results after several weeks. Patients must attend multiple sessions to see an improvement. For treatment, the patient either sits under a light or the dermatologist uses a wand on specific areas. The patient must wear eye protection during the session. The light feels warm but doesn’t cause any pain. The noninvasive procedure does not require a recovery period after treatment.

FDA approved home treatments offer another option. People seeking LED treatment can purchase a home device, either face masks or wand. Light therapy masks stay on the face for around 10 minutes, while you can rub a wand over the skin for 20-30 minutes. You can choose the color you want to treat your skin, depending on the condition you plan to target. If using a mask, make sure to clean it after each use. Store your mask or wand in a cool, dry place.

What type of treatment works best?

Each type of treatment has its own advantages and disadvantages. Dermatologist treatments tend to cost more than home treatments, but also tend to work better than the home treatment. A dermatologist has more expertise than the average person when it comes to using the device. A home LED device not only saves money but helps save on time getting to and from the dermatologist’s office.

Are there risks or side effects?

Overall, LED light therapy offers a much safer option than other types of light, including the sun. LED lighting gives off no ultraviolet, or UV, wavelengths of light. Although rare, using LED light therapy may result in some mild side effects, such as inflammation, rashes, skin redness, or tenderness. Do not use LED light therapy if you take certain medications or topical treatments that cause sensitivity to sunlight.

While you may think of LED lighting primarily for illuminating rooms, LED technology offers a multitude of benefits! LED skin therapy provides a safe and easy option for treating skin conditions and helping you to live a happier and healthier lifestyle!
