Salmonella Is Killed By SAFE Blue Light
Did You Ever Notice That Sunlight Is Beneficial For Clearing Acne?
Most people who have tried will agree that natural sunlight seems to have a beneficial effect on their skin and reduces severity of spots. Why does this happen?
Sunlight itself contains a wide spectrum of light, parts of which are beneficial and other parts which are harmful. We know that:
Pure blue light in the SAFE visible light spectrum of 405-470 nm can kill a range of bacteria including MRSA, Staph, Strep and most importantly Propionibacterium Acnes, the main microorganism linked to acne. While not beneficial for skin health directly, blue light doesn’t harm us like excess ultraviolet will and has been used successfully for years by dermatologists and patients looking for a solution to acne.
How does blue light kill the acne-causing bacteria?
Acne causing bacteria have a weak link in their metabolism – a chemical called porphyrin.
This naturally produced chemical is sensitive to blue light and other visible light, which energizes it, sending it on a destructive path around the bacteria cell.
This activated porphyrin ultimately kills the bacteria (by creating singlet oxygen which combines with cell parts – destroying them), without harming the skin.
Answer: Blue light therapy is often used to treat acne flare-ups. It treats acne thru wavelengths of blue light—this light has antibacterial effects thus making it ideal for removing specific bacteria kinds which gather on oil glands and pores. It also reduces redness and has anti-inflammatory benefits that helps sooth and relieve skin. Red light therapy, while it does not have similar antimicrobial properties unlike blue lights, are effective when it comes to facilitating healing of the skin. Red lights can also help in lightening acne scars and reduce redness. Red light wavelengths penetrate deep into the skin’s surface to relieve and repair damaged tissues. These types of light therapies are often gentle, painless, safe and drug-free.
Answer: Blue light therapy for acne is not a treatment that everyone can use. Pregnant women and people diagnosed with epilepsy, lupus, albinism and porphyria cannot make use of LED lights. In addition, if you are currently using acne and skin care products that contain antibiotics or retinol, you have to stop application of those products one week at the least to go through a session of blue light therapy. While most over-the-counter acne medications are safe to use with blue light therapy, it is still advised that you go over the acne treatment and check if it is suitable to use with blue lights/LEDs.
Answer: Just like any other skin care product, you have to be committed to this routine to see results. Results for blue light therapy for acne will be based on the dose of the light source provided. Blue light devices meant for home use are weaker compared to clinic-based ones thus they need to be used every day. In-office blue light therapy doses meanwhile are stronger and clients need to undergo this therapy at least twice every week.
Blue light kills the bacteria that causes the acne and the red light speeds up the healing. Navy Seals use red light beds to help heal them after a mission.
