Red light therapy (RLT) has come to the forefront for its potential in treating various skin problems like wrinkles, redness, acne, and scars. Although more research is needed to determine its true effectiveness, if you are curious to try this option for addressing signs of aging, it’s always best to discuss it with your healthcare provider first.
Red light therapy: what is it?
Using low-wavelength red light, red light therapy (RLT) can reportedly reduce wrinkles, scars, redness, and acne, among other conditions.
There is currently a lot of research on the potential effectiveness of red light therapy across a wide range of health applications, as well as the publication of smaller-scale studies and extensive online discussion. The overall efficacy of red light therapy remains to be fully established, even though some studies have shown promising results.
Red light therapy is also known as:
-
- Laser light therapy at low levels.
- Laser therapy with low power.
- LED light that is non-thermal.
- Therapy with soft lasers.
- Therapy with cold lasers.
- Photonic stimulation, biostimulation.
- The use of photobiomodulation and phototherapy.
What led to the interest in red light therapy?
Initially, red light therapy was explored by NASA as a means to promote plant growth in space and facilitate wound healing in astronauts. Over time, the research expanded, leading to investigations into other potential applications of this therapy.
Red light therapy has gained significant acceptance in the medical field, particularly in the application of photodynamic therapy. This treatment method involves the use of low-power red laser light to activate a photosensitizer drug, leading to a chemical reaction that effectively eliminates cells. Photodynamic therapy utilizing red light is commonly employed for treating a range of skin conditions such as skin cancer, psoriasis, acne, warts, and various other types of cancer.
Currently, RLT treatments are being investigated (or used) for a wide range of health conditions. However, the effectiveness of the treatment for these purposes is unclear.
What is the supposed mechanism of action of red light therapy?
Red light therapy is believed to operate by targeting the mitochondria, often referred to as the “power plants” of cells within the body. By providing an increase in energy, cells are able to perform their functions more effectively, including skin repair, promoting the growth of new cells, and enhancing skin rejuvenation. In particular, specific cells have the ability to absorb light wavelengths, which then stimulate their activity.
Skin health may benefit from red light therapy in the following ways:
-
- Boost collagen production, which gives skin its structure, strength, and elasticity.
- Skin is made up of connective tissue made up of collagen, which is produced by fibroblasts.
- Circulate blood to the tissues.
- Cellular inflammation can be reduced.
- What skin conditions are being treated with red light therapy?
- Some common skin conditions can be treated with red light therapy, including:
- Heal wounds more quickly.
- Stretch marks can be reduced
- Wrinkles, fine lines, and age spots can be reduced.
- Enhance the texture of the face.
- Psoriasis, rosacea, and eczema can be improved.
- Scars can be improved.
- Skin that has been damaged by the sun can be improved
- Increase hair growth in people with androgenic alopecia.
- Get rid of acne.
Does red light therapy work?
Researchers are still unclear about the effectiveness of RLT for all its claimed applications. Some studies have shown some potential for certain conditions, but more studies are needed. Red light therapy is still an emerging treatment that is generating increasing interest. However, most of its uses are not supported by enough evidence at this time.
Randomized, placebo-controlled trials are the standard for determining a product’s efficacy. In these studies, participants with similar traits (age, weight, race, gender) are subjected to either an experimental treatment or a placebo (fake treatment). Occasionally a comparison to a widespread treatment is included for further analysis. The outcomes of the study can then be compared between those who received the emerging therapy and those who did not receive any (the placebo group) or against an already existing procedure.
Several of the studies published on red light therapy (RLT) involved a limited sample size, lacked a placebo group, were conducted on animals instead of humans, or focused solely on cell tissue. While many researchers acknowledge the promising nature of the results obtained thus far, they emphasize the necessity for high-quality studies involving larger participant cohorts. Further research of this kind is required to establish the effectiveness of RLT more conclusively.
How safe is red light therapy?
If used as directed and short-term, red light therapy does not appear to cause any side effects. RLT does not use ultraviolet (UV) light, like the sun or tanning booths, which can cause cancer. This type of light is not toxic, not invasive, and not as harsh as some topical skin treatments.
It is important to note that misusing red light therapy products, such as using them excessively or not following the provided instructions, can potentially result in skin damage or harm to the eyes if proper protection is not used. The long-term safety implications of devices utilizing red light therapy have not been fully determined at this time.
To ensure your safety, it is recommended to consult with a dermatologist or a qualified and trained cosmetic therapist. Seeking the expertise of a dermatologist will allow for an accurate diagnosis of your skin condition and provide an opportunity to discuss the potential benefits of red light therapy along with other available treatment options.
