Light therapy is an increasingly favourite thing doing rounds these days that boosts physical and mental health with a non-invasive and drug-free method. There are quite a few available light therapies, but blue, green, and red light therapy have their unique benefits. It helps knowing the difference so that you can select the appropriate treatment according to your requirements.
What Is Light Therapy?
Light therapy is the application of particular wavelengths of light on the body with the use of LED devices. These lights penetrate the skin at different depths and excite various biological processes. Light therapy is now becoming the treatment of choice for those wishing to explore an alternative approach to health, whether easing pain and inflammation or improving skin tone and mood.
Now let’s break down how each color is working and what it is mostly used for.
Red Light Therapy: The Anti-Aging and Healing Powerhouse
How it works:
Red light therapy is based on a wavelength range of 620 nm to 750 nm. This wavelength penetrates deep down into the skin, to muscle or even bone tissue. This, in turn, stimulates mitochondrial function, the energy powerhouse of the cells, and helps in the repair and regeneration of cells.
Benefits of red light therapy:
- Skin Rejuvenation: Red light is widely used for beauty purposes to treat wrinkles, fine lines, and age spots. Collagen production is promoted to make skin firmer and appear younger.
- Wound Healing: It speeds natural healing and is thus useful in post-surgical recovery or injury.
- Pain and Inflammation Relief: Promotion of blood circulation and repair of tissue may assist with reducing chronic pains and inflammation.
Who it’s for:
Great for anyone looking to improve skin health, recover from injuries, or manage chronic pain.
Blue Light Therapy: The Acne Fighter
How it works:
Blue light therapy wavelength usually ranges from 405 within the 470 nm even though these wavelengths are shorter to penetrate and kill bacteria target skin surface layers.
Benefits of blue light therapy:
- Acne: Inhibits the bacteria P. acnes responsible for acne, thus making it an effective treatment for-breakouts.
- Reduction of Oil: It decreases sebaceous (oil) glands activity, which increases the amount of clogged pores.
- Improved Mood and Sleep: Good doses of blue light might reset its circadian rhythm, especially for those with seasonal affective disorders (SAD).
Who it’s for:
Ideal for those struggling with acne, oily skin, or needing help managing seasonal mood shifts.
Green Light Therapy: The Calming and Balancing Light
How it works:
Green light therapy works in the range of 495 nm to 570 nm. Green light penetrates a bit deeper than blue light and is mostly used for its calming and balancing effects.
Benefits of green light therapy:
- Relief for Migraines: Current studies show migraine intensity and frequency can be reduced by green light.
- Treatment of Hyperpigmentation: The green light may aid in lightening sunspots, age spots, and other discoloration by restraining melanin production.
- Calm and Relaxing: It’s said to calm the nervous system, therefore reducing stress and anxiety.
Who it’s for:
Perfect for people looking to even out skin tone, reduce stress, or manage migraines.
Can You Combine Them?
Definitely! Several devices offer multi-wavelength light therapy to address different concerns simultaneously. For example, the combination of red and blue light is frequently used in acne treatment: blue light kills bacteria, while red decreases inflammation and aids skin repair.
Beneficial when done right! But always wiser to check in with a healthcare professional or dermatologist before trying any new form of treatment, especially if you have any medical conditions or are taking light-sensitive medications.
