Θεραπεία με μπλε-κόκκινο φως: Ένας πλήρης οδηγός
Blue-red light therapy is a non-invasive, θεραπεία χωρίς φάρμακα που χρησιμοποιεί δύο συγκεκριμένα μήκη κύματος φωτός για να στοχεύσει προβλήματα δέρματος και υγείας. Χρησιμοποιείται στη δερματολογία, σπα, και οικιακές συσκευές για την ακμή, αντιγηραντική, επούλωση πληγών, και φλεγμονή.
Πώς λειτουργεί
1. Μπλε φως (415– 450 nm) goes into the surface layers of the skin (1–2mm) and targets the oil glands and bacteria.
Key benefits:
It kills the bacteria that cause acne (Π. ακμής).
It can also reduce excess sebum (oil) παραγωγή.
The FDA has approved it for mild to moderate acne.
2. Κόκκινο Φως (630– 660 nm)Penetrates deeper (5–10mm)Stimulates cellular repair & κολλαγόνο.
Key benefits:
It boosts collagen and elastin (which help with anti-aging).
It also reduces inflammation and redness (ροδόχρου ακμή, σημάδια ακμής).
It also speeds up wound healing, whether from burns, cuts or other procedures.
Why combine them?
Για την ακμή: Blue kills bacteria, while red reduces redness and scarring.
Μελέτη: Combining the two treatments improved acne 77% compared to 50% with blue alone (Journal of Cosmetic and Laser Therapy).
For ageing skin:
Red smooths wrinkles and blue prevents spots.
For healing after treatment:
Blue prevents infection, while red speeds recovery (π.χ., after peels/laser).
