LED Therapy: The Power of Light for your Skin

LED therapy has become increasingly popular over the years as a non-invasive, pain-free, and effective treatment for various skin conditions, pain relief, and wound healing. 3With its growing popularity, you may be wondering what exactly LED therapy is and how it works. This article will explore the science behind LED therapy, its different types, and its benefits for different conditions.


What is LED therapy?

LED therapy is a treatment that uses specific wavelengths of light to stimulate cellular activity. These lights are typically red, blue or green and are emitted from LED panels that are placed close to the skin. The treatment is painless and has no downtime, making it a popular choice for those looking for a quick and effective solution to a variety of skin concerns or pain.


Types of LED therapy

There are several types of LED therapy available, including:

  • Red LED light therapy: Red light therapy uses wavelengths of light that penetrate deep into the skin to stimulate collagen production and improve skin texture. This type of therapy is commonly used to reduce the appearance of fine lines and wrinkles, as well as to promote healing and reduce inflammation. Red light therapy can also be used to improve circulation and relieve pain.

  • Blue LED light therapy: Blue light therapy uses wavelengths of light that are absorbed by porphyrins, a type of molecule produced by acne-causing bacteria. When the porphyrins absorb the blue light, they produce a chemical reaction that kills the bacteria. This type of therapy is commonly used to treat acne and other skin conditions caused by bacteria.

  • Green LED light therapy: Green light therapy uses wavelengths of light that are absorbed by melanin, a pigment that gives skin its color. This type of therapy is commonly used to reduce the appearance of hyperpigmentation and other skin discolorations. Green light therapy can also be used to improve the appearance of scars and to reduce redness and inflammation.


How does LED therapy work?

LED therapy works by penetrating the skin with specific wavelengths of light. These wavelengths stimulate cellular activity, which can have a variety of benefits depending on the specific wavelength used.


What are the benefits of LED therapy?

LED therapy has a wide range of benefits, making it a versatile treatment option for a variety of concerns. Some of the most common benefits of LED therapy include:

  • For acne: Blue light therapy is an effective treatment for acne because it targets the bacteria that cause breakouts. By killing the bacteria, blue light therapy helps reduce inflammation and prevent future breakouts.

  • For wrinkles and fine lines: Red light therapy stimulates collagen production, which helps reduce the appearance of wrinkles and fine lines. Collagen is a protein that gives skin its elasticity and youthful appearance, and as we age, our collagen production decreases.

  • For hyperpigmentation: Green light therapy can help reduce hyperpigmentation by targeting the melanin-producing cells in the skin. By breaking down excess melanin, green light therapy can even out skin tone and reduce the appearance of dark spots.

  • For pain relief: Infrared light therapy is a non-invasive, drug-free way to relieve pain. It works by increasing blood flow and reducing inflammation, which can help relieve pain and stiffness in the muscles and joints

  • For wound healing: Infrared light therapy can also promote wound healing by increasing blood flow to the affected area and stimulating the production of collagen. This can help speed up the healing process and reduce scarring.

  • For hair growth: Red light therapy can also be used to promote hair growth by stimulating blood flow to the hair follicles and increasing the production of ATP, a molecule that provides energy to cells.


Are there any side effects or risks associated with LED therapy?

LED therapy is a safe, non-invasive treatment with few side effects or risks. Some people may experience mild redness, swelling, or dryness after treatment, but these side effects usually subside within a few hours. It's important to note that LED therapy should not be used by people with certain medical conditions, such as epilepsy, lupus, or porphyria. It's always best to consult with a healthcare professional before starting any new treatment.


Who can benefit from LED therapy?

LED therapy is beneficial for a wide range of people, including those with acne, wrinkles, fine lines, hyperpigmentation, pain, and wounds. It's also safe for most skin types, making it a great option for those with sensitive skin.


How to prepare for LED therapy

Before starting LED therapy, it's important to clean your skin thoroughly and remove any makeup or skincare products. You should also avoid sun exposure and tanning beds for at least 24 hours before treatment.


How to maintain results from LED therapy

To maintain the results of your LED therapy treatments, it's important to continue practicing good skincare habits and avoiding behaviors that can damage your skin. This includes wearing sunscreen daily, avoiding excessive sun exposure, and using gentle, non-irritating skincare products. For pain relief, you may need to continue with periodic LED therapy treatments, depending on the severity of your pain.


How quickly will I see results from handheld LED therapy?

The time it takes to see results from LED therapy can vary depending on the individual's skin type, the condition being treated, and the frequency and intensity of the treatments. In general, many people report seeing noticeable improvements in skin texture, tone, and appearance within a few weeks of starting regular LED therapy treatments.

Some individuals may see results more quickly, while others may take longer to see noticeable improvements. It is important to remember that consistency is key with microcurrent LED therapy - regular, ongoing treatments are typically necessary to achieve and maintain optimal results.

Factors such as age, skin type, and lifestyle habits can also impact the speed at which results are achieved. For example, individuals with more mature skin or those with more severe skin concerns may take longer to see results compared to those with younger or less problematic skin.


Can I use handheld LED therapy in conjunction with other skincare treatments?

Yes, it is generally safe to use LED therapy in conjunction with other skincare treatments. In fact, combining different skincare treatments can often enhance the overall benefits and results.

However, it is important to be cautious and avoid over-treating the skin, as this can lead to irritation or other negative side effects.


Is LED therapy safe for all skin types?

Yes, LED therapy is safe for most skin types, including sensitive skin.


How long does a LED therapy treatment take?

The length of a LED therapy treatment can vary depending on the specific device being used and the treatment protocol being followed. However, most treatments can be completed within 10-20 minutes, making them a convenient option for those with busy schedules.


How many LED therapy treatments do I need to see results?

The number of treatments needed depends on the specific concern you're treating.

It is important to note that while some individuals may see immediate results after just one treatment, most treatment protocols recommend multiple sessions over the course of several weeks or months to achieve optimal results. This is because LED therapy works by stimulating the skin's natural healing and rejuvenation processes, which can take time to fully manifest.

The frequency of treatments will also depend on the individual's unique skin concerns and goals. Some people may only need to use their LED handset once a week, while others may benefit from more frequent treatments.



LED therapy is a safe, effective treatment for a variety of skin concerns and pain. By using specific wavelengths of light, LED therapy stimulates cellular activity and promotes healing, while also reducing inflammation and improving overall skin health.
