Procedure for LED Light Therapy

Light therapy can be performed at home or in a clinician’s office. The biggest benefit to in-office light therapy is access to a professional who can advise you about the best treatments for your skin.

There are also many pros of using an at-home device for LED light therapy. For example, it’s much cheaper in the long run. The best results come from using light therapy on a regular basis—sometimes multiple times in one day, depending on the skin condition you are treating.

LED light therapy comes in many forms for home use. Devices include LED masks, lamps, and light wands for spot treating. Some home units combine light therapy with ultrasonic treatment—high-frequency vibration using sound waves to help your skin absorb the light.

LED light therapy can also be found as a component of multiuse devices. For example,mesotherapy electroporationdevices improve the skin’s ability to absorb light using electrical current.

Preparing for Light Therapy

Before a light therapy treatment, clean your skin with a mild cleanser and pat dry. Your skin should be free of any makeup. During the week leading up to your treatment, avoid any grooming techniques that can irritate your skin, such as waxing or shaving. If your eyes will be exposed to the light during treatment, you’ll need to wear goggles for protection.

After an LED Light Session

Light therapy sessions are often complete within 15 to 30 minutes but could take longer if you’re treating a larger area of your body. There isn’t any required “recovery time” after LED light treatment. Most people can resume their normal skin-care routine immediately afterward.

Uses and Benefits of LED Light Therapy

LED light therapy is used to treat a variety of skin conditions, including:

LED light therapy can treat certain types of cancer, as well. However, this type of treatment is currently only available in a medical professional’s office. Light therapy is also used for aesthetic purposes, such as reducing fine lines and wrinkles and making skin softer and smoother.

Results Can VaryWhile research has shown that LED light therapy can be effective for treating skin conditions and improving a person’s overall appearance, it does not work for everyone. For some conditions, such as cold sores, you might notice results within a few treatments. However, most conditions require several weeks of consistent treatments to begin to show improvements.

In general, LED light therapy is a safe, low-risk treatment. This type of therapy uses wavelengths that are on the visible light spectrum—not theultraviolet raysthat frequently cause skin damage and burns.

However, there are still potential negative side effects to treatment, including redness, burning, or skin irritation. Light therapy can also cause headaches, fatigue, irritability, hyperactivity, or difficulty sleeping.

Certain medications, such as oral contraceptives, antibiotics, antidepressants, and antihistamines, can make your skin more sensitive to light.If you take medication, talk to your healthcare provider to be sure light therapy is safe for you.

How to Get LED Light Therapy

LED light therapy devices can be purchased at retail stores or online. These devices range in cost from less than $30 to several hundred dollars. Devices that provide additional treatments, such as sound waves or electrical currents, are more expensive.

Dermatologists(medical doctors who specialize in skin conditions) also perform LED light therapy as part of treatment for specific skin conditions.

Summary

There are minimal risks with LED light therapy, but skin irritation can occur—especially if you take medications that make your skin more sensitive to light. While many people report that LED light therapy has fixed their skin woes, it doesn’t work for everyone.
