Bacteria are sensitive to light, and visible blue light at 415 nm at a high intensity is proven to be the best light available to kill bacteria that live on your skin. Scientists explain that the wavelength range of 402-420 nanometres has the most effective antimicrobial spectral range.
What is the wavelength of Bluelight?
380nm to 500nm Blue light, also know as high energy visible (HEV) light, has the shortest wavelength of visible light (380nm to 500nm), and therefore produces the highest amount of energy. HEV blue light produces both benefits and concerns for our eyes and overall health.

What does your face look like after blue light treatment?
Immediately following treatment, the area may be red, swollen, tender, and mildly bruised or blistered, especially when medication has been applied to the skin. The treated area may crust over or peel, but this is considered normal. Most people heal within 7 days, and the crusting resolves within 3 to 14 days.
Does blue light reduce pores?
For those who are hoping to reduce acne or make pores appear smaller, Skotnicki recommends blue light therapy. This is because the light may help shrink your oil glands, which in turn can reduce the oil production in your skin.

What is light NM?
Light is measured by its wavelength (in nanometers). … Visible light is usually defined as having wavelengths in the range of 400–700 nanometers (nm) or one billionth of a meter. EM waves are categorized according to their wavelengths and frequencies (number of waves passing a point in a certain time).
Is blue light the color blue?
Some are visible to the human eye, such as the colours red, orange, yellow, green, blue, and violet. Others are invisible, such as infrared and ultraviolet. Blue light is a colour in the visible light spectrum and falls within the 400-500nm range.
What can be measured in nanometers?
A nanometer is used to measure things that are very small. Atoms and molecules, the smallest pieces of everything around us, are measured in nanometers. For example a water molecule is less than one nanometer. A typical germ is about 1,000 nanometers.
Are blue LED lights bad for eyes?
The blue light in LED lighting can damage the eye’s retina and disturb natural sleep rhythms, France’s government-run health watchdog said this week.
Is blue light really bad for your eyes?
It’s safe to say most of us spend a lot of time staring at screens. And that can be bad for our eyes. Blue light from electronics is linked to problems like blurry vision, eyestrain, dry eye, macular degeneration, and cataracts. Some people have sleep issues.
Is Nano blue light Safe?
Contact with harmful blue light (between 380 and 450 nm) can lead to age-related macular degeneration. This means that, over time, retinal cells can become irreversibly damaged.
What is CVS Computer Vision Syndrome?
Computer vision syndrome (CVS) is strain on the eyes that happens when you use a computer or digital device for prolonged periods of time. Anyone who has spent a few hours on the computer has probably felt some of the effects of prolonged use of the computer or other digital technology.
What wavelength is bad for humans?
UV and blue-violet light (380 – 495 nm) are the wavelengths with the highest energy, and are thus potentially the most harmful to the human eye.
What should I put on my face after blue light treatment?
Keep skin moisturized with Hydrocortisone 1% ointment or Aquaphor for the next 3 to 4 days. Wash your face with the Gentle Vitamin Cleanser. You may experience mild swelling for 1 to 3 days after treatment.
Does blue LED light cause hyperpigmentation?
Blue light also induces hyperpigmentation that can lead to sunspots or dark spots by affects the production of melanin in your skin cells — the dark pigment responsible for tanning your skin in response to sunlight exposure.
Do blue light therapy pens work?
Blue light therapy is often touted by Med Spas as recommended for treating spider veins and varicose veins. However, this is often because it is a treatment that doesn’t require administration by a doctor and thus it is the only option they can offer. However, the truth is that it’s not proven to be effective.
Does blue light work on spider veins?
Blue-light therapy may be more likely to work on smaller spider veins than larger varicose veins, but it may not have a noticeable effect. However, blue-light therapy has been shown to work as an acne treatment, so it may help people with other issues related to the appearance of the skin.
Do blue lights help depression?
Research indicates that blue light is superior to other lights in the spectrum for treating depression. Studies show that blue light can be used at a specific wavelength and frequency at less intensity than full spectrum bright light to achieve the same kind of effects.
Which Light therapy is best for acne?
Blue light therapy is the type of light therapy most commonly used to address acne breakouts. The wavelength of blue light has an antimicrobial effect, making it effective at killing several types of bacteria that can collect in your pores and oil glands and cause breakouts.

The signals that blue light sends to your brain can also disrupt your body’s production of the sleep hormone melatonin. This can make it hard to fall asleep and stay asleep after using your devices at night. And beyond sleep quality, melatonin disruption throws off the entire hormone balance in your body.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
