How LED Light Therapy Can Rejuvenate Your Skin

Written by prositesdentalSep 8 • 3 minute read

As an innovative skin care treatment, light-emitting diode (LED) light therapy has been steadily gaining popularity over the years. This advanced procedure can improve your skin integrity in many ways. It is a non-invasive, painless, and safe way to rejuvenate your complexion, reduce inflammation, and improve the youthful aesthetics of your skin. Continue reading to discover more about this procedure and help you decide if this treatment is right for you.

What is LED Light Therapy?

LED therapy is a non-invasive treatment that improves your skin complexion by stimulating its natural reaction to light. Different LED light colors emit different wavelengths, each with unique advantages to the skin. Depending on your needs, your skin care professional will recommend which light is right for you.

How It Works

Red and blue lights are the two most commonly used colors in LED light treatments. Red (infrared) light is absorbed into the skin and promotes the production of collagen, which makes your skin look smoother and fuller. This color can also help reduce inflammation and improve circulation to give you a healthier, more youthful appearance.

In contrast, blue light can reduce the activity of sebaceous glands, which produce the oils in your skin. These oils help keep your skin lubricated and prevent it from drying out. However, too much oil can plug your hair follicles and cause acne. Blue light is also known to kill bacteria beneath the skin that can cause more severe cases of acne, preventing future breakouts.

LED light therapy is a low-risk way to help improve your skin’s integrity and complexion.

What Should I Expect During Treatment?

Though there are many devices that allow you to perform this procedure at home, a professional dermatologist employs advanced equipment that uses stronger lights and produces more consistent results. Depending on the type of procedure and color of light being used, you will sit under an LED light, a therapy device will be placed on your skin, or a wand will be waved over the treatment area. Typically, this process takes about 20 minutes, and you may require multiple visits to achieve the results you’re looking for.

What Does LED Light Therapy Treat?

Studies show that LED light therapy can treat a variety of different skin conditions. LED light therapy can also be safely used in combination with other treatments for more advanced or complex concerns. Some of the treatable conditions include:

  • Hair Loss
  • Eczema
  • Psoriasis
  • Acne
  • Sun Damage
  • Actinic Keratosis
  • Wrinkles
  • Rosacea

Is the Procedure Safe?

A non-invasive treatment is any procedure that does not physically puncture the skin. With LED light therapy, the light-emitting diodes never penetrate the skin. Additionally, LEDs do not increase in temperature, so there is no risk of burning your skin with this procedure.

However, LED light therapy is not ideal for those taking medications that increase sunlight sensitivity, like lithium or isotretinoin. Those with histories of skin cancer and inherited eye disease should also avoid the procedure. As with any cosmetic procedure, it’s crucial to follow your skin care professionals recommendations for how to prepare your skin for LED light therapy and how often to undergo the treatment.


LED light therapy is an innovative, safe, and reliable way to rejuvenate the aesthetics and health of your skin. With no recovery time, this procedure allows you to return to your daily activities without delay. Ultimately, only a skin care professional can determine if LED light therapy can produce the results you’re looking for. Once you receive the information you need, you’ll be able to make an informed decision about whether this modern treatment is right for you.
