Background:
Interest in anti-aging approaches has grown significantly in recent years. The most popular are the non invasive methods to decrease the signs of aging. One such method is LED-based therapy.
Methods:
This study investigated the potential of two different wavelengths, 590 nm and 630 nm, combined or not, in the photobiomodulation of proteins involved in the slowdown of the skin aging.
Results:
These in vitro results on cell viability, cell shape, and mitochondrial function support and build on previous studies suggested that LED treatment is safe. Regarding its biological functions, our data indicated that the combination of two different wavelengths acted in synergy to enhance the impact of each irradiation alone. Combined, the LED wavelengths could improve in vitro the cell shape, the cell proliferation, and the level of major proteins involved in the healing process.
Conclusion:
These benefits may lead to reinforcement of the skin organization and structure. This hypothesis will be checked in future clinical studies.
