In the ever-evolving world of aesthetic treatments and wellness solutions, we all know that light therapy has emerged as a popular option.  A lot of people have been exposed to a lot of advertising, especially for red light, and by now in 2025 almost  every light color is purported to have special benefit.

At M-Shape Beauty, we're dedicated to providing our clients with the latest and most effective non-invasive technologies. Therefore we’ll never blindly accept propaganda that brainwashes consumers into believing something is safe or effective before thorough investigation. Now when it comes to violet light therapy, we would absolutely say it’s recommended to take a closer look.

Violet light, with a wavelength of around 405nm, has been advertised heavily for its various applications in the beauty and healthcare industries. From skin rejuvenation to antimicrobial properties, the claims surrounding this specific wavelength are intriguing at best.  Again, as a responsible provider of aesthetic solutions, we believe it's essential to approach this topic objectively and factually. And upon further investigation we’ve concluded the benefits of Violet light are low, and the risks are high, and here’s why:

UV Light is Already Proven Dangerous 

At 405 nm, the violet wavelength resides just outside of the traditional UV range, often considered the violet or 'near-ultraviolet' part of the spectrum.  Sellers of violet light therapy devices will argue - yeah we’re above the official cut off.  And then we’re like - yeah you sure are, by 5nm, less than 2%.

So we totally agree that 405nm light does indeed have  a very slightly longer wavelength than these extremely harmful types of ultraviolet light, making 405nm  potentially less of a cause for concern in terms of cancer risks. But come on, do you want to take the risk, when it’s so close?  And the overall risk of eye injury from 405nm lasers is comparable to other similarly powerful lasers of different wavelengths.

Now you might wonder - how does the seller of Violet light devices sell these things legally?  How do they have FDA at all?  That’s another topic and we are not accusing anyone.  But notice how high the prices are of some of these devices.  Corruption is not uncommon and those high prices must cover something.

Now back to the topic.  We’re concerned about safety and effectiveness…

Understanding Violet Light Therapy

Violet light therapy, also known as 405nm light therapy, utilizes the unique properties of this specific wavelength to target various skin concerns and conditions. The scientific theory suggests that violet light can penetrate the skin and interact with cellular structures, potentially stimulating collagen production, reducing inflammation, and even exhibiting antimicrobial effects. Ok this may be sort of true, I mean all light will interact with cells, but’s let’s checkout what else:

Potential Benefits

The claimed benefits of violet light therapy are wide-ranging, from improving skin health to addressing aesthetic concerns. Some studies have indicated that violet light may have a positive impact on acne-prone skin, thanks to its ability to target and eliminate acne-causing bacteria. Additionally, there are claims that violet light can enhance skin rejuvenation by stimulating collagen production, leading to a more youthful and radiant appearance. But where is the hard core clinical proof? There isn’t any.

Potential Risks

As we just noted, the safety and long-term effects of violet light therapy has not actually been extensively researched. There are concerns that prolonged exposure to violet light may potentially cause skin aging and other detrimental effects. The high-energy nature of violet light raises questions about its impact on cellular structures and the potential for damage over time.

While violet light is not advertised as harmful , the ultraviolet (UV) radiation associated with it, particularly UVA and UVB, can be damaging to the skin. Overexposure to these UV rays can lead to sunburn, premature aging, and even skin cancer. 

Here's a more detailed explanation

• Violet Light vs. UV Radiation:
  Violet light is part of the visible light spectrum, while UV radiation is invisible and has shorter wavelengths than violet light, and the wavelengths are very close.
  
• UV Radiation and Skin Damage:
  UVA and UVB rays can penetrate the skin and damage DNA in skin cells, potentially leading to skin cancer and premature aging. 
  
• Sources of Harmful UV Radiation:
  The sun is a primary source of UV radiation, but tanning beds and some types of artificial lighting can also emit harmful UV rays. 
  
• Importance of Protection:
  It's crucial to protect your skin from overexposure to UV radiation by using sunscreen, wearing protective clothing, and seeking shade during peak sunlight hours. 
  
• Not all UV is equal:
  UVC is very dangerous but is largely absorbed by the atmosphere. UVB is the primary cause of sunburn, and UVA penetrates deeper, contributing to long-term damage like skin cancer and aging. 
  
• Violet light therapy:
  Some advertisements suggest that violet light (laser or often LED) can be beneficial for skin, helping to even skin tone and reduce inflammation, but the hard core proof is not easy to find.
  

Other Light Therapy Options 

When compared to other light therapy modalities, such as red and green light, the scientific consensus on violet light therapy is less established. Red light therapy, for instance, has garnered significant attention for its ability to reduce inflammation, promote wound healing, and potentially aid in fat reduction. Green light therapy, on the other hand, has shown some promise for fat reduction.

Expert Insights and Research

As we continue to explore the potential of violet light therapy, it's essential to rely on the factual data, not just mere opinions and recommendations of medical and scientific experts because, for one thing,  these experts may be paid without your knowledge. Real research and clinical studies may shed more light on the true benefits, if any,  and the severity of the risks associated with this specific wavelength. Until then, we advise our clients to approach violet light therapy with extreme caution and stinky consider other non invasive solutions that are safer and much more effective as well.
