The wavelength of light determines how deeply light can penetrate the skin, with violet and blue light penetrating only into shallow layers of the skin and red light penetrating into the deepest layers of the skin. Red, blue, or a combination of red and blue light can be used to treat acne. Typically, a combination is used. For centuries, people who had acne were told that they needed the sun to dry outâ€ their skin. ðŸ”† While both dryness and sun are enemies of healthy skin, it turns out that the old advice to expose acne to the light of day was partially correct. Visible blue light, it turns out, can kill acne.
The advantage of these devices is convenience, as they can be used at any time without the need to see a doctor. However, at-home devices use a lower intensity of light and are therefore less effective than devices used in doctors’ offices. At-home devices are also often smaller than the devices used at doctors’ offices, and normally expose a smaller area of the skin to the light. This system comes with three easily changeable light wavelength settingsÂ Red Light (630nm), Blue Light (470nm), and Yellow Light ( 590nm). This allows for personalized treatment plans which target a range of skin conditions over the whole face.
While blue, red, and blue + red light devices may temporarily reduce acne, they do not completely clear the skin. Therefore, it is best to use light therapy alongside other proven treatments It is not known whether light therapy devices are effective in the long term. Physician-administered in-office light therapy appears to be more effective than weaker at-home devices. The patient is exposed to a blue light lamp for 15 to 20 minutes, usually bi-weekly for a period of four to six weeks. Often, after blue light treatment, red light is also applied as it is seen to activate ATP in skin cells and improve treatment response. The blue light acne treatment light also does not cause tanning or skin burn.
Acne bacteria are killed by visible blue light , that is, light you can see, not UV light, of wavelengths between 407 and 420 nanometers. The bacteria have pigments in their protective cell membranes that resonate at those frequencies. These pigments break down the membrane, eventually killing the bacterium. On a Petri dish, ðŸ§«ðŸ”¬ three exposures to blue sneak a peek here light kill about 99.99% of acne bacteria. 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.
The advantages of at-home treatments include the fact that there is minimal risk of side effects such as your skin peeling or drying, which can often occur with the use of topical prescription products. Also, there is less risk of your skin having an allergic reaction It is also pain free and can be safely used ðŸ¤°ðŸ½ðŸ¤± by pregnant women or women who are breastfeeding. Some of the side effects you might get from the treatment include swelling, stinging, redness, and burning. In some cases, some patients may react to the topical applications, though this rarely happens.

Thereafter reduce the treatment to three times a week to ensure that you do not get any skin breakouts.
However, the academy warns that acne does not usually completely clear up with phototherapy alone. The treatment panels have a large surface area which increases the speed of treatment and provides more consistent coverage of the skin. The modular design across the three treatment panels allows you here toÂ personalizeÂ your treatment by providing light therapy coverageÂ in different areas of your face with different skin conditions. For example, the blue light may be targeted at the T-zone where acne and blackheads are more prevalent and the red light around the eyes where wrinkles may appear.
Sadick, N. S. Handheld LED array device in the treatment of acne vulgaris. J. Drugs Dermatol. 7, 347 – 350 (2008). The machine works with the help of five working modes, which are yellow, red, blue, program 1 and program 2. The red light works on the skin for 5 to 20 minutes by penetrating deep into the skin tissue to increase microcirculation, stimulate collagen production and metabolism, and to activate skin cells. Blue light therapy treatment is usually a very quick process, and is almost always done as an outpatient procedure. The exception to this may be photodynamic therapy on high-risk areas for cancer treatment.
It is advisable to arrive at the doctor’s office before treatment with clean, makeup-free skin. The doctor will provide goggles to protect the eyes while the patient lies or sits under a blue light for the duration of the treatment. Most people do not experience any pain or discomfort. There are no noticeable side effects in most cases and where present, these are generally minor reactions. These may include temporary changes in the pigmentation (color) of the skin with some swelling and dryness in the treated area possible as well.
Blue light covers the spectrum from 407 to 420 nm. When blue light reaches the oilÂ glands in the skin, it can excite compounds produced by acne bacteria called porphyrins.3-5 When excited by light, these porphyrins kill the bacteria.6 Researchers are not sure whether blue light works in other ways as well. Strength of light devices: Tabletop light therapy devices employ weaker light than devices used at physicians’ offices. Works from day 1! Noticeable results seen in a matter of weeks. Treatment time is only 20 minutes per day, making it easier to fit into your skincare regime.
The yellow light helps to intensify the function of the muscles and improve the immune stem. It also helps to give the skin its balance by improving circulation, adjusting cytoactive, inhibiting the growth of melanin, removing freckles and reducing skin pigment. Others hide their acne and other skin imperfections with beauty products such as a foundation, concealer , bronzer or powder. All these products give the wearer a flawless smooth look but the acne still hides underneath all the makeup. Other solutions like acne creams, serums and lotions also work to eradicate the problems but while some may be lucky to get rid of the problem, others may not be so lucky and still make endless visits to a dermatologist.
Elman, M., Slatkine, M. & Harth, Y. The effective treatment of acne vulgaris by a high-intensity, narrow band 405-420 nm light source. J. Cosmet. Laser Ther. 5, 111 – 117 (2003). Studies show that at-home treatments are decently effective at helping clear inflammatory acne and they’re generally safe to use in addition to other treatments. If you are suffering from acne then you may know that there are various causes (hormones, genetics, diet, etc.) but it always forms because of a blockage in follicles, skin organs that produce hairs. The sebaceous glands are attached to these follicles and produce sebum. Excess of sebum will allow the Propionibacterium acne bacteria to propagate and form papules, nodules and other inflammatory lesions.
Blue light therapy uses light to treat certain conditions on or just under the skin. It’s considered a pain-free procedure. According to the American Academy of Dermatology , light therapies show great promise in treating acne,â€ with many people experiencing a significant improvement in their skin health after a number of sessions. Omi, T. et al. 420 nm intense continuous light therapy for acne. J. Cosmet. Laser Ther. 6, 156 – 162 (2004). Benefits of light therapy include low side effects and potentially longer-term results. Drawbacks include incomplete, temporary, and often poor results, and difficulty in application-it can take 10-60 minutes a day to treat the skin with light.
Blue light therapy uses light in the blue wavelength range to kill the bacteria Propionibacterium acnes, or P. acnes, on the skin. When using blue light therapy on a daily basis, it will eliminate the bacteria and decrease the amount of inflammation, allowing you to see your skin get purer and look much vibrant. It’s been demonstrated that the acne bacteria suck the light from blue LEDs, which will activate a group of an organic compound to release oxygen, killing the bacteria. One benefit to the use of acne blue light therapy is that the treatments do not scar the skin and tend to improve skin texture lessening the appearance of existing scars. Some possible side effects would include, temporary dryness and redness in the area of treatment. Other than side effects, the cost can get expensive if a lot of treatments are required.
