RED LIGHT THERAPY
Red light therapy (RLT) is an emerging treatment that’s showing promise in treating wrinkles, redness, acne, scars and other signs of aging. Many researchers say more clinical trials are needed to confirm its effectiveness as a treatment. If you’re interested in red light therapy, ask your healthcare provider if this is an option for your skin issue.
Unleash the Power of Light: Explore Red Light Therapy
Ever wondered if light could hold the key to healing and rejuvenation? Well, with red light therapy, that’s exactly what it can offer! This innovative approach utilizes specific wavelengths of red light to deliver a range of potential benefits for your overall well-being.
What is Red Light Therapy?
Red light therapy, also known as photobiomodulation, involves exposing your skin to concentrated, low-level red light. This light penetrates your cells, stimulating their natural healing and repair processes. The key lies in the wavelengths used. Red light therapy utilizes specific ranges that are readily absorbed by your cells, triggering a cascade of positive effects.
Potential Benefits of Red Light Therapy:
- Skin Health: Red light therapy has been shown to be effective in reducing the appearance of wrinkles and fine lines. It may also promote collagen production, leaving your skin looking healthier and more youthful.
- Pain Relief: Studies suggest red light therapy can be beneficial in managing pain caused by various conditions like arthritis and muscle soreness.
- Wound Healing: Red light therapy may accelerate wound healing by promoting tissue regeneration and reducing inflammation.
- Improved Mood: There’s growing evidence that red light therapy can positively impact mood and may help with symptoms of seasonal affective disorder (SAD).
Is Red Light Therapy Right for You?
While red light therapy is generally considered safe, it’s always wise to consult with your doctor before starting any new treatment, especially if you have any underlying health conditions.
So, stay tuned as we embark on this journey into the transformative power of light!
What does red light therapy actually do?
Red light therapy is thought to work by acting on the “power plant” in your body’s cells called mitochondria. With more energy, other cells can do their work more efficiently, doing things like repairing skin, boosting new cell growth and enhancing skin rejuvenation.
How does red light therapy supposedly work?
Red light therapy is thought to work by acting on the “power plant” in your body’s cells called mitochondria. With more energy, other cells can do their work more efficiently, doing things like repairing skin, boosting new cell growth and enhancing skin rejuvenation. More specifically, certain cells absorb light wavelengths and are stimulated to work.
Red light therapy may work in skin health to:
- Stimulate collagen production, which gives skin its structure, strength and elasticity.
- Increase fibroblast production, which makes collagen. Collagen is a component of connective tissue that builds skin.
- Increase blood circulation to the tissue.
- Reduce inflammation in cells.
For what skin conditions is red light therapy being tried?
Red light therapy is promoted as a treatment for some common skin conditions, including to:
- Improve wound healing.
- Reduce stretch marks
- Reduce wrinkles, fine lines and age spots.
- Improve facial texture.
- Improve psoriasis, rosacea and eczema.
- Improve scars.
- Improve sun-damaged skin.
- Improve hair growth in people with androgenic alopecia.
- Improve acne.
Is red light therapy effective?
Most experts say that they don’t know yet if RLT is effective for all its claimed uses. Most say that the studies published so far show some potential for certain conditions, but that more studies need to be conducted. Red light therapy is still an emerging treatment that’s generating growing interest. But at this point in time, there’s not enough evidence to support most uses.
The gold standard of studies to determine if a product is effective is a randomized, placebo-controlled trial. This means that a certain number of people with the same range of characteristics (age, weight, race, sex, etc.) get either the study treatment or a placebo (fake or “sham” treatment) for treatment of the same condition.
Some studies also include a comparison to another commonly used treatment. Results can then be compared between the emerging treatment versus no treatment (the placebo group) or versus a “current standard” treatment.
Many of the published studies using RLT included only a small number of people, didn’t include a placebo group, weren’t conducted in humans (animal studies) or were limited to cell tissue itself. Most researchers say results so far look promising, but that more quality studies with larger numbers of people are needed.
Is red light therapy safe?
Red light therapy appears to be safe and isn’t associated with any side effects, at least, if used short-term and as directed. This therapy isn’t toxic, not invasive and not as harsh as some topical skin treatments. Unlike the cancer-causing ultraviolet (UV) light from the sun or tanning booths, RLT doesn’t use this type of light.
However, if products are misused — perhaps used too often or not according to directions — there’s a chance your skin or eyes (if not protected) could be damaged. The long-term safety of devices that use red light therapy isn’t yet known.
Your safest option is to see a dermatologist or qualified, trained, cosmetic therapist. A dermatologist can make sure your skin condition is what you think it is and can discuss the merits of red light therapy and other treatment options.
Are devices purchased for at-home use a safe, reasonable option?
You’ll find many red light therapy products if you search on the internet. While these products are generally safe to use, they may be less powerful than devices that may be used by dermatologists or other trained skin professionals. You may not get the results you hope for.
If you do choose to purchase a red light therapy device, make sure to shield your eyes for protection, follow all directions and take good care of the device.
In addition to medical office-based use and at-home use with a purchased device, you may see RLT being promoted at beauty spas and salons, saunas, tanning salons, gyms and wellness centers. Be cautious of who is supplying and where you are receiving treatment. It’s always best to check in with a medical professional about the best options to treat your skin condition or issue.
What other medical conditions is red light therapy being promoted for?
Other potential medical uses being investigated include:
- To reduce cancer chemotherapy side effects, including oral mucositis.
- To relieve pain and inflammation associated with ankle tendonitis, rheumatoid arthritis, carpal tunnel syndrome and osteoarthritis of the knee.
- To prevent cold sores from herpes simplex virus from recurring.
Lots of other uses are being touted on the internet. There’s no scientific evidence to support red light therapy use in weight loss, cancer, cellulite removal or mental health conditions like depression and seasonal affective disorder (SAD).
What else do I need to know about red light therapy?
There are a lot of variables to consider when thinking about red light therapy:
- Is RLT covered by my health insurance? Red light therapy typically isn’t a covered treatment. You may want to call your health insurance company before seeking treatment.
- How many treatments will I need? You’ll likely need ongoing treatments. This isn’t a one-time treatment for most skin conditions. You’ll need to be seen one to three times a week for weeks or even months. Also, is there a need for additional touch-up treatments? This may add up to a lot of time and considerable out-of-pocket costs.
- Will I achieve the desired results? Everyone’s skin is different so results can vary. Also, the wavelength of the red light source ranges. The wavelength affects how deeply the light penetrates your skin. The wavelength of the red light device being used in a doctor’s office versus in your at-home device could affect your desired result.
- Do you trust the experience of the person providing the red light therapy? For example, is a tanning salon a place you feel comfortable receiving this treatment or might it be better to first be seen and possibly treated by a medical professional?
- Is red light therapy an appropriate treatment for my skin condition? Are other, more scientifically vetted approaches a better choice for my skin condition? See your healthcare provider to confirm a diagnosis and discuss appropriate treatment options.
