by Light therapy over the years has been shown to bring positive results when used for skin healing. Most people who have used light therapy for their skin report that they can see visible improvements consistently. What is great about red light therapy is that there is enough clinical evidence to back this claim.
Red light therapy operates on a cellular level as it can reach the mitochondria at certain wavelengths. The skin absorbs it and starts cellular repair, eventually resulting in cleaner and brighter skin.
So, let’s talk about all the ways you can promote skin healing with non invasive methods like light therapy.
How Light Therapy Works for Skin Healing?
The Science Behind Light Therapy for Skin
Now, you may wonder how light therapy works. We mentioned that it essentially stimulates the mitochondria to produce more collagen.
Light therapy, in theory, is prevalent in the process of photobiomodulation. This is a mechanism where you can use specific wavelengths of light to stimulate cellular processes.
As a result, you can use this to accelerate natural skin repair and regeneration. Research shows that these wavelengths accelerate natural skin repair and regeneration.
Cell Regeneration and Collagen Production
With an increased production of collagen and elastin, red light therapy can ensure your body can grow healthy skin over multiple sessions. More collagen production strengthens connective tissues that can help smooth fine lines, heal acne scars, and remove stretch marks.
Improved Circulation and Reduced Inflammation
Light therapy also improves overall blood flow which reduces inflammation. Both of these steps are important for healing the skin.
So, an increased blood flow can bring essential nutrients and oxygen to the skin which in turn speeds up the skin healing. You can reduce swelling and minimize redness common in skin problems like rosacea and acne.
Key Light Wavelengths Used in Skin Healing
It is crucial to remember that different wavelengths of light can be used to target specific skin issues ranging from removing marks to healing pain.
1.Red Light Therapy
Red light therapy is primarily used for surface-level skin problems. Operating at wavelengths around 630 to 660 nm, it can penetrate the upper layers of the skin to produce more collagen and elastin.
With more production, you can improve skin elasticity and firmness. Thus red light is used to heal skin problems like fine lines, sun damage, and redness and reduce inflammation.
In many cases, people also use red light to heal autoimmune problems like rosacea and psoriasis.
2.Blue Light Therapy
Moving on to blue light between wavelengths 400 to 470 nm, you can help heal acne and bacterial skin infections.
Blue light does not penetrate as deeply as red light but can be used to neutralize bacteria that trigger acne. It can also be used to prevent scarring and future breakouts.
3.Near-Infrared Light Therapy
Near-infrared light therapy operates at wavelengths 800 to 850 nm. This can penetrate deeper into the skin to reach tissues.
This can be used for healing injuries and deeper muscle tissues. As light therapy improves blood circulation athletes use them for healing wounds and repairing muscles.
Many doctors also recommend this after surgical or cosmetic procedures.
Evidence of Skin Healing Results from Light Therapy
Clinical Studies and Research Outcomes
To solidify light therapy’s success in the medical world, here are a few studies to look into if you are unsure of its benefits.
- Acne: One study found that blue light therapy at 415 nm helped doctors reduce acne lesions over 12 weeks. It targeted killing the bacteria that topical treatments were not able to remove.
- Healing scars: Another research showed that post-surgical patients treated with red light therapy managed to remove scars by increased blood circulation to the affected area.
- Anti-Aging: Red light’s benefits in terms of reversing skin aging can also be found in a clinical trial. This trial reported that these wavelengths increased skin firmness and elasticity which helped reduce fine lines and wrinkles. The 79 participants saw a 32% improvement in skin texture after treatments over 8 to 10 weeks.
Before and After: Real-World Results
Acne Treatment and Reduction
In many cases, patients who use blue light therapy for acne often see clearer skin within weeks. Studies show that acne scars can be reduced by light therapy’s antimicrobial properties which can even prevent the future spread of bacteria.
Anti-Aging Effects and Wrinkle Reduction
Red light therapy is often used for anti-aging treatments where clinical findings show great results in reducing wrinkles. In one study, patients showed a 26% improvement in reducing wrinkles after several weeks of red light therapy.
Improved Skin Tone and Texture
Many patients dealing with hyperpigmentation or uneven skin texture can use red and near-infrared light to reduce discoloration. A study showed that patients saw radiant skin after a few sessions of regular treatment.
4 Major Benefits of Light Therapy for Different Skin Concerns
Here are all the benefits that light therapy can bring to your skin over sessions.
-
Ance and Acne Scars
Blue and red light are great for reducing acne and acne scars. Blue light at 415 nm can target acne-causing bacteria on the skin’s surface to reduce breakouts. Red light between 630 to 660 nm can be used alongside blue light therapy to reach deeper layers of skin to rejuvenate the skin by increasing collagen production.
- Fine Lines, Wrinkles, and Age Spots
Red light therapy in particular can be used to reduce fine lines, wrinkles, and age spots. Red light can penetrate the skin deeper than blue light to help firm the skin and smooth out wrinkles. Using this with other face products can speed up the process.
-
Inflammatory Conditions (Rosacea, Psoriasis)
For inflammatory skin conditions like rosacea and psoriasis, light therapy has shown great results in selected patients over time. Red and near-infrared light can reduce inflammation and soothe the skin. Near-infrared light can reach deeper tissues to reduce irritation.
-
Wound Healing and Scar Reduction
For healing wounds and scars near-infrared light therapy is the best way to go. As it penetrates the skin more the blue and red light combined, and it can heal scars faster. Many patients use this post-surgery too to remove pregnancy marks. It can also be used to close open wounds faster making it a great option right after surgery too!
How to Maximize Skin Healing Results with Light Therapy?
Ideal Treatment Frequency and Duration
For the best results, you need to chalk out a treatment plan based on what you need to treat. For acne treatment choose blue light for 10 to 20 minutes two to three times per week. Red light therapy is best for anti-aging which can be done over the same amount of time in more frequent sessions.
Combining Light Therapy with Skin Care Products
The best way to make light therapy effective for you, pair it with skincare products. Products that have hyaluronic acid can be applied before and after red light sessions to help retain moisture in the skin. Peptides can be used to speed up collagen production and can align well with red and near-infrared therapies.
Professional Treatments vs. At-Home Devices
It is best to consult a doctor for a professional light therapy treatment as they use stronger industrial-grade equipment. It can be great for deeper healing.
However, now you can find equally capable devices at home too. It is just that professional treatments are faster and regulated so you do not have to worry about poor form.
For more serious skin conditions professional treatments can be best as you get real-time feedback from your doctor on what’s working and what isn’t.
Safety and Side Effects of Light Therapy for Skin Healing
Potential Side Effects of Light Therapy for Skin Healing
Although light therapy is generally safe, it can cause mild side effects for some individuals. These include redness, skin irritation, and burning sensations.
However, these are only prevalent in users who have sensitive skin or are under certain medications. These effects are also not long-lasting so you do not have to worry about it.
Sometimes light therapy can also trigger headaches and eye strain. These are generally due to not using protective eyewear or overusing the therapy at home. It is best to consult with a doctor to solve these issues by having a proper routine made for you.
Contraindications and Precautions
Light therapy is not for everyone as people with photosensitivity, lupus or epilepsy can be at risk from exposure. Medication like certain antibiotics, antidepressants, and contraceptives can also cause problems in the long run as they increase light sensitivity.
Remember if you have a history of skin cancer or genetic eye conditions stay away from it until you consult a doctor.
