How does Light Therapy Help Acne?

Acne is one of the huge skin concerns that most people have. Several skincare products are available in the market that promises to treat acne. However, very few of them actually work without harming the skin further. 

One of the amazing treatments for acne is light therapy. In this treatment, natural healing and light antibacterial properties are utilized to reduce acne conditions without any drastic side effects naturally. 

In this article, we will discuss this in detail.

Light Therapy for Acne Treatment

Oil deposition and dead cells in hair follicles are two of the primary causes of acne. When these particles get stuck inside the skin, they will start to irritate it. Eventually, one will see blackheads, pimples, and whiteheads from the irritated portion of the skin. 

Moreover, if those particles are not removed, bacteria attack those deposits, and the area gets infected. Thus, one will experience inflammation and infections on their skin.

Many people invest in creams, lotions, or therapies to get rid of their acne condition. However, most of them can associate additional side effects with making the acne condition worse or bringing outs some other side effects. Other than these products, some utilize natural home remedies that work slower to show significant improvement. 

In this manner, light therapy is one of the best treatments available right now. This therapy is completely natural, has no drastic side effects, and works faster to show significant results.

This therapy aids in controlling oil particles. A wide range of visible light and near-infrared wavelengths are used on the skin to help people with acne-prone skin avoid skin irritation.

In general, red light therapy offers significant benefits in treating acne. Other than that, blue light, green light, and amber light are also found in some devices to help users cope with acne.

Let’s discuss these therapies:

Red Light and NIR Light Therapy

Red light therapy is one of the most used therapies used for a wide range of skin benefits. This light has the largest wavelengths among other visible light; therefore, it can penetrate the upper skin layer to help with skin problems.

630 – 670 nm red light wavelengths work best in handling acne. These wavelengths energize the mitochondria in skin cells to improve metabolism. Thus, damaged skin cells start to repair themselves to resolve skin problems.

Once the healthy repair is introduced, the cells can then replicate themselves to rejuvenate the skin area. Also, increased metabolism influences blood circulation to deliver blood all over the body. This helps deliver oxygen and nutrients all over the body while driving away oil particles and dead cells from acne-infested skin areas. 

Moreover, collagen protein production increases with the help of red light wavelengths. Collagen protein keeps the skin flawless and helps keep it intact. 

In addition to red light, near-infrared light offers some additional benefits. These light wavelengths are invisible to human eyes and slightly bigger than red light wavelengths. In therapy, 810 -860 nm near-infrared light wavelengths are used for therapy.

These light wavelengths offer similar therapeutic benefits as red light therapy and more. As these wavelengths slightly warm up the skin area, the clotted pores open up to remove harmful particles. Additionally, the warmth kills bacteria to protect the skin from getting inflamed and developing infections.

Red light and near-infrared light also boost melatonin hormone to soothe the skin and control oil production. Thus one will see significant improvement right after their first session.

Benefits of Other Colored Light Therapy 

In addition to red light and near-infrared light, blue, green, and amber LED lights are also used in resolving skin health conditions.

Blue light has the smallest light wavelength among visible lights. Therefore, this light cannot go deeper into the skin. However, it has antibacterial properties that kill harmful bacteria to protect the skin from acne infection. Moreover, blue light increases serotonin production and wakes up the skin to remove impurities. 

Green light and amber light are used to soothe skin from acne damage. These wavelengths work to calm the skin and help repair the area giving the users flawless skin.

These additional lights are often featured in light masks or wands. However, some companies are now incorporating blue light in their light therapy panel.


Light therapy is completely natural and has virtually no side effects. However, if the user has overly light-sensitive skin, it is recommended to use sunscreen and other protective methods.

Some users may find the therapy light too bright. In those cases, they can use protective eyeglasses to cover their eyes. 

If the user experiences any redness or irritation on the skin due to light therapy, they should contact a doctor immediately.

Bottom Line

Many people across the globe struggle with their acne condition and face several problems. They utilize various treatments to get rid of this condition. However, most acne treatments have drastic side effects that can worsen the skin condition.

In contrast, light therapy is very effective in treating acne conditions and has virtually no side effects. This therapy utilizes the antibiotic and healing properties of natural light and allows users to get the benefits of light any time of the day. 

However, while buying a light therapy device, ensure that the device emits the right light wavelengths. Otherwise, it won’t bring the desired results.
