Blue light, Is It Worth It?
When looking at remedies for various skin conditions, blue light therapy has come to be a rising prescription for many. As previously discussed, red and blue light therapy has been proven to harbor many benefits for our skin’s health. The question is, what are these benefits and potential downsides?
Blue light, similar to red light, is known to erase acne, scars, and boost collagen production. It emits blue light waves between 380 and 500 nanometers. This technology can kill off bacteria within the skin to prevent breakouts. Dr. Dendy Engelman told Women’s Wear Daily that it is a safe and non-invasive treatment option for stubborn acne. The treatment is best known for being anti-bacterial. If you are someone who is active in sports (sweating frequently), someone who wears a mask daily, or just anyone with relentless acne I would recommend looking into this treatment.
One of the main downsides that people encounter with this remedy is that it can only target what light can see. In other words, what’s on the skin or just below it? Another scientific discovery that has come about in recent years is the safety of this method. Low energy and low-exposure times will have many benefits for our skin’s health. However, exposure for longer amounts of time can damage the skin barrier, irritate the eyes, and cause more harm than good.
Overall, if used properly and safely, this treatment has many benefits for acne-prone skin types. Although some prices may seem jarring on Amazon, the cost of these devices can be as low as 30.00 US dollars. If you are able to get your hands on one, make sure to read/listen to directions carefully, and stay consistent, and you should see some magical results coming your way!
