Using Blue Light Therapy To Treat Acne
Written by Jason Popper
Can light actually be beneficial to your acne? A common acne myth: sunlight treats your acne. However, even as a myth, there are some truths to this statement. Sunlight does help treat acne, but overexposure has shown to make acne worse. Many skin doctors ask acne sufferers to stay out of the sun, and with good reason. Also, many of the acne treatments prescribed to acne sufferers require them to avoid sunlight. But, can sunlight be beneficial?
It was a difficult task for scientists to figure out why sunlight initially helped treat acne. If there was a certain aspect of sunlight that could be separated from the rest and used solely to treat acne, this would become a great acne product. After researching the different wavelengths and their effects on acne, scientists concluded that blue light, almost violet light, at 415nm indeed does treat acne. Also, red light at 660nm and above improved skin collagen production, which would be great for other skin defects as well. But, our main conce
is the 415nm wavelength and how it treats acne.
Why does blue light treat acne? Acne is caused by bacteria thriving in your clogged pores. By shining blue light at the acne, the light provides an uninhabitable environment for these bacteria, killing them off in just under a week. This allows acne to quickly disappear, sometimes in even less than 24 hours. Blue light therapy works great for even severe acne, because severe acne is packed with bacteria that needs to be destroyed.
The results blue light therapy has shown for the treatment of acne were on an average scale. It is by no means a miracle acne treatment, but it is effective for most types of acne. It is a decent alte
ate to acne creams and pills if those didn't work for you in the past. Although, since blue light therapy doesn't help treat clogged pores, purchasing a product that keeps the pores clean and the bacteria out will complete your acne treatment regimen if you decide to try out blue light therapy. There are many acne treatments being developed today; one of them just might happen to work for you.

Respiratory Infections and Pollution Effects - Causes, Symptoms & Prevention Tips
Abstract Respiratory infections are becoming increasingly common, and one of the major contributing factors is the rise in air pollution. Polluted air contains harmful particles, chemicals, and toxins that weaken the lungs and reduce the body’s natural defense mechanisms. As air quality worsens in cities, people of all age groups are experiencing more frequent coughing, breathing difficulties, allergies, and long-term respiratory diseases.

Why Barometric Pressure Triggers Headaches - Causes, Symptoms & Prevention Tips
Many people notice that their headaches or migraines worsen when the weather changes. One of the most common culprits is barometric pressure, also known as atmospheric pressure. This pressure refers to the weight of the air around us, and even small shifts can affect sensitive individuals, often leading to headaches, sinus pressure, or migraines. What Happens When Barometric Pressure Drops? A drop in barometric pressure is common before storms, rainfall, or sudden weather c

Research of Cell Membrane Nano Drug Delivery System and Its Application in Bionic Nanomedicine
Most of the old drugs are currently limited in their effectiveness because of poor pharmacokinetics, simple clearance by the body and cytotoxicity. Nanoparticle technology in particular, Nano drug delivery system is getting a lot of attention and application in medicine in the recent years. Since it is small (1100nm), targets well, and stays in the circulation long enough, NPs are a good candidate as a drug carrier, enabling an enhanced in vivo targeting capability and less n

Research on Regulating cAMP Pathway to Chronic Obstructive Pulmonary Disease
The world's chronic disease, chronic obstructive pulmonary disease (COPD), is among the most incredibly morbid and mortal. A relatively common, preventable and curable condition, COPD most often reflects itself in chronic breathing problems and airway obstruction. Its cause is elusive and not well understood. The most important pathological processes involve oxidative stress, protease dysfunction, mitochondrial dysfunction and airway inflammation. Drug and oxygen treatment ar
