Re-wind a couple of years, and NASA notices an increase in plant growth under certain wavelength of light. They think; if it works on plants, why not skin? They noticed that when red LED lights were shone on astronauts, wounds tended to heal faster. NASA began experimenting with LEDs to speed the healing of wounds, because in zero-gravity situations, wounds don’t quite heal as fast as they would otherwise. Research revealed, cells exposed to LED light regenerate 150 to 200 percent faster than those not stimulated by the light. LED light, or photodynamic therapy, was then developed by NASA in 2003 including a groundbreaking report detailing its healing properties. It is now used as skin cancer treatments and cosmetic arenas. So in other words, if NASA say it works, we aren’t arguing!
What is LED Light Therapy?
First, LED therapy stimulates cells called fibroblasts which produce collagen. It also slows down the production of enzymes which break down collagen and make older skin lose its elasticity. LED lights also speed cell production, making skin regenerate faster which creates fresher-looking complexions. The treatment works by using pulses of low level light energy to safely activate the mitochondria within the cells. The cell then converts the light energy into fuel which is used to produce proteins and lipids, which are used to repair the skin. Ultimately this process promotes collagen production and increases the rate of skin cell renewal. A recent study into the efficacy of the therapy revealed that in just 24 hours of a single treatment of LED light there was as much as a massive 200% increase in collagen fibres.
Why Choose LED Light Therapy?
As well as being pain-free and non-invasive, with no known side effects and no downtime, there are many benefits to choosing LED therapy. With this therapy you will see and feel results instantly. After you first treatment your skin will feel tighter and more vibrant as a result of greatly increased circulation, oxygenation and moisture. You will be able to visually observe softening of fine lines, increased skin firmness and a refreshed, healthy glow. The main results of LED light therapy include:
- Speeds up healing process and alleviates pain after surgery
- Increased collagen and elastin production for up to six months after your treatment
- Reduction of fine lines
- Reduction of pigmentation
- Calming and soothing of the skin, meaning reduced redness
- Anti-inflammatory action
- Strengthening of capillary walls
- Improvement of rosacea
- Rejuvenation of the skin
Who can benefit from Light Therapy?
Light therapy is beneficial for various individuals, offering positive effects on different aspects of their health and well-being. For those with skin conditions, LED light therapy can be used for treating various skin conditions, such as acne, psoriasis, and rosacea, as it can stimulate collagen production and reduce inflammation.
But additionally, some studies suggest that light therapy may enhance athletic performance and muscle recovery in athletes. And light therapy has shown promising results in alleviating symptoms of certain mood disorders, including Seasonal Affective Disorder (SAD).
Who should avoid LED Light Therapy?
While light therapy can be beneficial for many, there are certain groups of individuals who should avoid or use caution with LED light therapy. These include:
- People with Retinal Diseases. Individuals with retinal disorders or diseases should avoid light therapy, as it may worsen their condition.
- Individuals on Photosensitising Medications, the use of light therapy in combination with these medications may cause adverse reactions.
- People who are extremely sensitive to light should approach light therapy with caution, as it may lead to discomfort or worsen their sensitivity.
- Pregnant Women
What are the side effects of LED light therapy?
LED light therapy is generally considered safe when used appropriately, but like any medical treatment, it may have some side effects. These can include:
- Skin Irritation: Some individuals may experience mild irritation or redness on the skin after light therapy sessions. This reaction is usually temporary and subsides quickly.
- Dryness or Peeling: In some cases, LED light therapy may cause dryness or peeling of the skin, especially when used for dermatological treatments.
- Hyperpigmentation: Prolonged or improper use of light therapy on the skin may lead to hyperpigmentation, causing darkened spots on the treated areas.
- Eye Discomfort: Staring directly at the LED lights without proper eye protection can cause eye strain and discomfort.
- Sleep Disruptions: If used too close to bedtime or at incorrect times of the day, light therapy may disrupt sleep patterns or circadian rhythms, leading to sleep-related issues.
It’s essential to use LED light therapy under the guidance of a healthcare professional, especially when targeting specific medical conditions or skin treatments. If any adverse reactions occur, it’s best to discontinue use and consult a healthcare provider.
