The Science Behind Red Light Therapy and Penetration Depth

When we talk about light, it’s not just about the thing we used to see with our eyes, there’s a lot of spectrum science out there, from the blues to the red and far beyond what our eyes can detect. While you explore these wavelengths, it reveals some pretty interesting interactions with your body tissues.

Here’s, how it goes down: Compared to other wavelengths in the spectrum, red light and near-infrared light between the wavelength of 660nm and 890nm get absorbed by your skin cells–especially by those mitochondria–you know the powerhouse of your cells.

Once it enters your skin tissues, approximately 80% of the red light energy is absorbed in the first 2cm which then continues with activating several biological reactions, leading to an increase in cellular turnover, superficial circulation, and an anti-inflammatory emission, just like the flicking of a switch for your cells.

First, it levels up the cell engines and boosts all the energy production. This turns your body cells to function better whether it’s about repairing tissues, fighting inflammation, or bringing that plump or youthful glow to the skin.

And what’s the best part? RTL does all this without any harmful effects or downtime. Imagine giving your body a gentle nudge in the right direction to help it heal itself.

So, when you buckle around with a Red light therapy belt, know that there’s some serious science working at work, giving you a buzz of energy, and your body gets a little booster inside out.

Is Red Light Therapy Safe?

Red Light therapy is the most safest and non-ablative technique and doesn’t involve any harmful UV rays as with those found in sunlight or tanning beds. The spot red light used during this therapy generally falls within the visible and near-infrared spectrum of wavelengths, which is well tolerated by human skin.

However, there are some limitations that require your highest attention while usage. This includes adhering to the specifications and recommendations of the red light therapy device and equipping yourself with precautionary eyewear to shield the eyes from direct light exposure.

And if you get careless when exposing your skin to red light for too long, mind you, you can end up with Skin irritation, damage, and burns. Also, Avoid getting in contact with red light therapy if you’ve photosensitivity or have any underlying medical conditions.

Types of Clothing That May Affect RLT Efficacy

To make the most of Red Light therapy, it’s often advised to administer the red light therapy device directly to the skin. However, if you prefer modesty or comfort in wearing clothes during treatment, it is best to go with thin, light-colored, and loosely woven fabrics.  This allows a greater amount of red light to reach the skin layer, maximizing the therapy's effectiveness. Conversely, tight-fitting or thick fabrics may obstruct the light and reduce its penetration.

Light and breathable fabrics, such as cotton or linen, are best suited as these materials enable the light to reach the skin more efficiently, maximizing its healing properties.

When it comes to color, it's best to stick with lighter shades such as white and light grey. These colors reflect red light and penetrate well into the skin, unlike darker colors that absorb more light and may hinder its penetration.

And…Not to mention, the weave of the different fabrics also influences its light penetration, as tighter weaves tend to obstruct heavy light as compared to those with looser weaves. There are some cases in which specialized clothing is designed for the sake of light therapy; fabric materials are optimized to pass desired light wavelengths while fabric provides adequate coverage.

To enhance the permeability of red light through clothes, Yolumistore has developed red light therapy devices that can be worn on the body. These Red Light Therapy Devices, are specifically designed to emit therapeutic red light directly onto the skin, even if clothing is worn. They provide a convenient solution for those who prefer to have clothing on during treatment sessions.

Considering Some Practical Implications

  1. To get accelerated and high RLT benefits, go with fabrics that are lightweight and breathable with fewer layers. Garments with fewer weaves or lighter tones are way more suitable and allow light penetration to a great extent. However,  in order to obtain optimal results for the sake of skin health or wound healing, there should be direct skin exposure to light
  1. If you aim for targeted therapeutic effects, definitely go for direct skin exposure via an RLT device. This would minimize all of the potential restrictions caused by clothing pieces and will pass the light directly to the skin and its underlying tissues.
  1. Sometimes, when you stick around situations where RTL usage is more practical over clothing due to privacy concerns or modesty, Opt for clothing that has appropriate properties, like it should be lightweight or less opaque; this would help to improve the overall effectiveness of RLT.

Empirical Studies Or Expert Opinions On The Effectiveness Of RLT Through Clothing.

Different empirical studies have explored the impact of different fabric materials on the transmission and absorption of red light, and further investigate whether RLT can harness desired physiological outcomes when applied via different clothing types.

As per the findings, the outcomes vary depending on factors such as fabric type, thickness, or targeting specific light wavelength to be set in the therapy. Findings showcase that RLT has the ability to penetrate the clothing to some point, but the varying degree of penetration might be influenced by different evident factors.

Fabrics that were thinner or more translucent, such as lightweight cotton or any synthetic materials, allowed a rather big proportion of light to pass through clothing, resulting in noticeable benefits.

Conversely, fabrics that were thicker or kind of opaque, such as denim. leather or any heavy wool, obscure light penetration; ultimately reducing the therapy's effectiveness.

Many studies even point out the positive results of RLT application while it's administered via clothing, especially for the sake of wellness applications. But, for therapeutic purposes like skin rejuvenation and skin exposure to light, these are generally taken into consideration for generating optimal results.
