Blue Light Therapy 101

Blue Light Therapy

Blue light therapy is a non-invasive treatment that uses blue light to target specific skin conditions, including acne, and even mental health conditions like Seasonal Affective Disorder (SAD). This type of therapy is gaining popularity due to its effectiveness and minimal side effects.

In this article, we will discuss what blue light therapy is, the conditions it can be used to treat, the benefits of using a blue light therapy wand, and how to properly use it.

What is Blue Light Therapy?

Blue light therapy is a type of light therapy that uses blue-spectrum light to target common skin problems, such as acne. The blue light is thought to penetrate the skin and target the bacteria that cause acne. This therapy can also be used to treat SAD, a form of depression that occurs during the fall and winter months when there is less natural sunlight. The light is thought to mimic natural sunlight and help regulate the body’s circadian rhythm, which can improve mood and energy levels.

What Can Blue Light Therapy Treat?

This can be used to treat a variety of skin conditions, including acne, eczema, psoriasis and rosacea. It has also been shown to help reduce the appearance of wrinkles and age spots. In addition, blue light therapy is believed to help soothe irritated skin.


This therapy also reduces inflammation and helps prevent new breakouts from forming. This makes it an effective and non-invasive alternative to traditional acne treatments such as topical creams and oral medications.

A study has shown that blue light therapy is effective in treating mild to moderate acne. Participants in the study showed a significant reduction in the number of acne lesions after just four weeks of treatment with this. Additionally, there were no reported side effects, making this an attractive option for those looking for acne treatment with minimal risks.

Seasonal Affective Disorder (SAD)

SAD is a type of depression that is related to changes in seasons, specifically shorter days and reduced sunlight during fall and winter. The lack of natural sunlight can disrupt the body’s circadian rhythm and lead to feelings of depression, fatigue, and a lack of energy.

It has been shown to be effective in treating SAD. It is believed that the blue light emitted by the therapy mimics the natural sunlight, and by doing so, it helps to regulate the body’s internal clock (circadian rhythm). This regulation can lead to an improvement in mood and energy levels.

Other Potential Uses

This is also effective in treating other conditions as well. It has been used to treat skin conditions such as eczema and psoriasis by reducing inflammation and promoting healing.

Moreover, some studies have also suggested that blue light therapy may promote hair growth. This is due to its ability to increase blood flow to the scalp and stimulate the growth of hair follicles. However, more research is needed to confirm these potential uses.

Benefits of Blue Light Therapy

There are many potential benefits to blue light therapy. Some of the most notable benefits include:


It is considered a non-invasive treatment option. This means that it does not involve any surgical procedures or other invasive methods that may cause pain or discomfort.

Minimal Side Effects

This is a huge advantage as it allows people to undergo the treatment without worrying about severe reactions or complications. Some people may experience minor skin irritation or dryness, but these side effects are usually temporary and can be easily treated with a moisturizer or other over-the-counter products.


Compared to other treatments such as laser therapy or topical medications, blue light therapy is more affordable. This makes it an accessible option for those who are looking for a cost-effective treatment that can provide effective results.

How to Use Blue Light Therapy?

Using this light therapy is relatively simple. Depending on the type of device you use, you may be required to place it in a certain position or distance from the skin so that it can direct the light appropriately. It is important to follow the manufacturer’s instructions and not exceed the recommended treatment time.

Types of Devices

There are different types of these devices available, including blue light therapy wands and light boxes. A blue light therapy wand is a handheld device that can be used to target specific areas of the skin, while light boxes are larger devices that can be used to treat a larger area of the skin or to treat SAD.

Dosage and Duration

The dosage and duration of treatment will vary depending on the condition being treated and the device being used. A typical treatment session for acne may last between 10 and 20 minutes, while a treatment session for SAD may last up to 30 minutes. It is important to follow the manufacturer’s instructions for your specific device.

Safety Precautions

It is important to keep in mind some safety precautions when using blue light therapy.

  • Do not look directly into the blue light as it may cause eye strain
  • People who have certain medical conditions such as lupus, diabetes or those who are pregnant should not use blue light therapy without consulting with a doctor first.
  • It’s also important to protect your skin from UV rays during and after treatment.

Blue light therapy is a safe and effective treatment for many conditions, but it is important to follow the instructions and safety precautions when using it. Talk to your doctor or healthcare provider to determine if this type of therapy is right for you. With proper usage and care, this can be an effective way to treat various medical conditions.
