Beneficial Blue Light for Acne vs. Bad Blue Light Exposure

Learn About Blue Light for Acne Treatments | Reduce Harmful Blue Light Exposure | LED vs. Light From Digital Devices | How Different Blue Lights Affect Skin

You’ve heard of blue light therapies for acne, but have you heard of blue light detriment? You might think that all blue light is the same, but repeat and frequent exposure to blue light devices can cause your health to suffer.


While there are benefits of LED blue light use, blue light damage occurs from exposure to high-energy visible (HEV) light. This blue light detriment is virtually unavoidable since everything from sunlight to LED TVs emit it.

Blue Light Detriment: What Is Blue Light and Why Is It Bad?

HEV light, the short form for high-energy visible light, is predominantly associated with energy-radiating items such as common blue light devices like modern TVs, laptops, tablet screens, and smartphones.


Since HEV blue light naturally occurs in sunlight, people are exposed to it everyday, but there is increasing concern regarding its exposure from commercial products.   

The Different Types of Blue Light Devices

Blue light devices, such as LED blue light for skin therapies, utilize blue light for positive purposes. Predominantly used for treating skin issues such as acne, these devices are examples of controlled blue light devices.

Uncontrolled blue light devices emit harmful blue light as a byproduct from the screens of everyday electronic products. LED screens cause manufactured blue light to be emitted during the illumination process.

While blue light devices can be beneficial for health, uncontrolled blue light emissions can have serious long-term health consequences. 


Beneficial Blue Light: Does Blue Light Treatment Work for Acne?

Blue light treatment for acne is a modern and proactive way to combat acne’s root causes. Blue light’s wavelengths treat acne by killing the bacteria responsible for its development.

Since its rays contain natural bacteria killing properties, both doctors and estheticians frequently use it for skin-related procedures.

Detrimental Blue Light: Understanding Blue Light Damage

Blue light damage negatively impacts the body through prolonged exposure to retina-penetrating rays. Damage most commonly occurs in the eye and contributes to irreversible macular degeneration and cataract development.

Main Risk Factors Associated With Blue Light Damage

While many of the long-term effects of blue light damage are not yet known, studies have shown that blue light exposure may be a contributor to breast and prostate cancer.


Surprisingly, blue light therapy is also used in medical environments to combat skin cancer by removing growths.  

Blue Light Detriment: Exposure From Mobile Devices and Blue Light Damage 

More people are turning to tech devices to support their busy lifestyles. That means increasing their exposure and raising their risk of blue-light-related health issues.

Using and interacting with blue light devices has resulted in greater instances of exposure-related damage being observed. 

Brain: What Does Blue Light Do to Your Brain?

Mimicking sunlight, the brain is awakened by  blue light emissions which make the brain think it’s daytime. Circadian rhythms and sleep cycles can be disrupted by blue light device usage at night causing insomnia, irritability, and difficulty focusing.



Skin: Does Blue Light Make You Age Faster? 

Blue light damage can occur on skin continuously exposed to its high energy rays.

Long-term exposure can cause an uneven tone, redness, and impeded cellular regeneration, which contribute to premature skin-aging. Photoaging is one of the most commonly observed issues involving skin exposure. 


Repeated use of blue light for health purposes, such as acne treatments, has not shown any long-term health effects or damage.


Using Blue Light for Acne Treatment

LED blue light is used to treat acne by harnessing its inherent microbial properties to kill and eliminate acne-causing bacteria. Blue light kills bacteria naturally and is effective in the targeted reduction and removal of contagions from skin.

How Do You Use Blue Light Acne Treatment?

Blue light therapies are performed at spas and dermatologists’ offices and are always executed by a professional. For protection, LED masks or shields are used to eliminate any potential damage to other areas of the body. 

What Does Blue Light Therapy Do to Your Skin?

Skin LED Phototherapy helps to reduce acne, eliminate bacteria, and promote skin-cell regeneration. Skin is revitalized through the elimination of pollutants leaving pores minimized and skin looking younger. 


How Long Does It Take for Blue Light to Kill Bacteria?

Blue light is able to kill bacteria related to acne in just under two minutes, making it a fast and effective way to combat and treat causes and breakouts. 


What Is the Best Blue Light Therapy for Acne?

While there are many new acne-mask products on the market that claim to use blue light technology, the positive or negative effects of these at-home consumer masks have not yet been proven.

If you’re looking for the best mask to combat acne, Bioenergetique should be your first pick because of its electrically charged clay properties and its unique ability to pull contaminants directly from skin.

For blue light acne treatment, however, the fastest and most effective procedure is Phototherapy.

Phototherapy only takes a few minutes and requires just one session to be effective. Containing anti-inflammatory properties, blue light is also used to treat acne that presents itself concurrently with rosacea and psoriasis.


Blue Light Devices:
Damage Can Happen When You’re Least Expecting It

While the power of blue light can be used for good, it’s beneficial applications are almost always done in a controlled environment, performed by professionals, and closely monitored. 


Conversely, daily blue light damage can happen virtually anywhere and is almost unavoidable when using technologies that incorporate LED screens into their products.

Blue Light Protection

To reduce blue light damage and the long term impacts caused by blue light devices, blue light detriment products may be used to combat these products’ negative effects.


While outside, skin and eyes can be protected from naturally occurring sunlight with high-SPF sunscreens and sunglasses, while products such as computer glasses can assist in blocking harmful HEV rays from LED screens. 


It’s important to be cautious about blue light protection since many items, such as blue light screen protectors, can reduce brightness and sensitivity to blue light but do not effectively block blue light rays from the retina.

Be Beauty Careful

At the end of the day, using the power of blue light to beautify your skin and fight acne is a terrific way to give your skin a beauty boost. Just remember to keep your distance from blue light-emitting screens, protect yourself with approved products where possible,  and be aware of the long-term potential damage.
