Because of its anti-inflammatory effects, doctors can also use red light therapy to help treat acne, often in conjunction with blue light, which doesn't penetrate as deep as red light, but has been shown to kill bacteria on the surface that cause acne. 6 “Both blue and red light have been Elma Baron, MD, professor of dermatology at Case Western University and head of the dermatology service at the VA Northeast Ohio Healthcare System, tells SELF that the choice really depends on the doctor's experience, preference, and the type of devices being used. Research also shows that it can help with wound healing, psoriasis, eczema and rosacea. 7 Experts say you're likely to see some skin-improving effects with red light therapy, but as with most skin rejuvenation treatments, the most visible results will be temporary.
But that's why regular use is recommended, whether in an office, spa, or at home. In other words, if you're looking to achieve smoother skin and see a reduction in fine lines, you'll need to hold your sessions so that each one supports and supports the other; then, over time, usually in a matter of weeks or months, you should start to see noticeable changes, according to the doctors I spoke to. When treating chronic diseases, users usually see results within one to four months, also depending on the frequency of red light therapy. RLT is most effective if you keep up with treatments on a regular basis.
For anti-aging, for example, most professionals recommend 2-3 treatments per week. How often you use light therapy often depends on your time and monetary budget. Keep in mind that phototherapy is cumulative, so more is usually better, but be sure to consult with your doctor or skin therapist for treatment guidance. The color, tone and thickness of your skin affect how quickly you absorb red light photons, so you may need to adjust the treatment time to get results.
Topical photosensitizers are creams or solutions that “allow the skin to better absorb red light so that the rays penetrate deeper and have more effect,” he explains. Chances are you've heard of LED light therapy, also known as low-level laser therapy or photobiomodulation. Similar to low-level laser therapy, low-level phototherapy delivered through light-emitting diode (LED) devices has the potential to treat a variety of skin (wrinkles and acne), as well as pain conditions and even hair and scalp conditions. There is some important research available on LED red light therapy and the effects of the sun on skin health.
Compared to low-level laser therapy, LEDs generate negligible amounts of heat and are not considered a significant risk to the general population. To date, there is a lot of ongoing research, the publication of small studies, and a lot of discussion on the Internet about the effectiveness of red light therapy for all types of health uses. The big difference is that red light therapy starts to help the body from the first session, and often multiple sessions provide long-lasting results. Red light therapy is also non-toxic, non-invasive, and a cost-effective alternative to prescription medications, invasive surgery, and aggressive topical skin treatments.
The best thing about red light therapy is that it's non-invasive and, when used correctly, it doesn't damage the skin. Red light therapy works to minimize scarring, inflammation, fine lines, and several other skin conditions. Collagen production can help heal wounds quickly and prevent scar tissue from forming; in these cases, red light therapy works quickly. Pulsed waves produce short, nanosecond bursts of high-power light, which deliver more light energy deeper into the body without heating tissues.
For UV rays to be in a red or near-infrared light therapy device, the manufacturer would have to place it there on purpose for a reason. As is the case with over-the-counter skin care products, simply make sure to remove any topical products before using phototherapy and apply them afterwards, according to your prescription instructions. Constant exposure to red light therapy can reduce symptoms of chronic skin conditions and promote skin health. .
