Terapia com luz vermelha: The main idea, what it does and how it’s used.
1. What is red light therapy?
Terapia com luz vermelha (Rlt) is a treatment that uses light to help the body heal. It uses special red and near-infrared light to target specific areas of the body. The most important idea is:
Photobiomodulation involves light penetrating the skin (até 5-10 mm deep), being absorbed by cell mitochondria, which helps to produce ATP (the energy that cells need to function). This, in turn, activates cell repair and regeneration.
It won’t cause any heat. Red light therapy is different from laser or ultraviolet light because it does not produce heat or damage the skin.
2. The main effects of red light therapy
Scientific research has shown that red light therapy can work in these ways:
Make your skin produce more collagen. This will make your skin softer and younger-looking.
If you want to relieve pain and swelling, you need to reduce the things in your body that cause inflammation (like IL-6 and TNF-α).
Make your blood circulate better and speed up how quickly your tissues are healed.
The way to sleep better is to regulate the production of melatonin in the body.
3. How it can be used (based on what we know from medical research)
💆♀️ Skin health and beauty
Anti-aging: make fine lines less visible and shrink pores (supported by a study in the Journal of Investigative Dermatology).
Treatment for acne: stop the bacteria Propionibacterium acnes from causing inflammation.
Scar repair: make surgical and burn scars less bumpy.
We can help you with pain management and sports rehabilitation.
Arthritis: find relief from osteoarthritis and rheumatoid joint pain (Lancet Rheumatology review, 2023).
If athletes get hurt, they will recover more quickly and have less pain.
Crescimento do cabelo
Androgenic alopecia: The FDA has approved red light caps for home use (like iRestore).
😰 Mood and nervous system regulation
There is an easy-to-understand way to treat depression. This involves regulating the blood flow to the brain and serotonin levels (as per a study in the Journal of the American Medical Association’s Psychiatry in 2022).
Sleep problems: help patients with insomnia to fall asleep more easily.
There are other possible uses for this.
Thyroid function: Animal studies show that it may improve a thyroid problem called Hashimoto’s thyroiditis (but more human studies are needed).
It helps mouth ulcers heal faster.
4. Things that should not be used together
Be careful in these situations or avoid using it:
❌ Photosensitivity diseases (such as porphyria).
Don’t take photosensitising drugs (like tetracycline or isotretinoin).
❌ Sites where skin cancer or melanoma is active.
5. How to choose a treatment plan?
This equipment is used in medical institutions. It is high-powered and professional guidance is required.
Home equipment: Choose FDA/CE certified products (such as Joovv, CurrentBody), 3-5 vezes por semana, 10-20 minutes each time.
Tip: The effect will take 4-8 weeks to appear, and it is recommended to combine it with healthy work and rest and nutrition.
