With increased human life expectancy and improved living standards, anti-aging has become a significant concern. As for anti-aging, this "battle against time" is especially obvious in today's beauty era. To stay young, people opt for various ways to fight aging, such as using skin care products, eating health supplements, getting cosmetic surgery, etc.
Do you want to achieve safe and healthy anti-aging benefits? Today, we will take a closer look at the potent anti-aging weapon - red light therapy.
How does red light therapy fight skin aging?
Red light therapy (RLT) uses 660 nm light-emitting diodes (LEDs) to regulate the activity of cells through non-photothermal action. This specific wavelength, often referred to as the "golden wavelength," can penetrate 8-10 mm into the skin, reaching the dermal capillaries and collagen layer. By doing so, it promotes microcirculation.
A current scientific study published in the Journal of Skin Research Tech demonstrated that red light LED therapy effectively reverses the visible signs of skin aging and improves skin quality after three months of treatment.
The red light therapy principle is mainly reflected in four aspects.
First, promote blood circulation. Red light therapy enhances blood circulation in the skin, increases the supply of oxygen and nutrients, and helps improve dull and bright skin tone. Good blood circulation can help speed up metabolism and promote the lightening and elimination of spots.
Second, increases collagen synthesis. Red light therapy stimulates the activity of mitochondria in skin cells, promoting collagen synthesis. Collagen is a crucial component in maintaining skin elasticity and firmness. Red light therapy enhances skin elasticity and decreases the appearance of wrinkles and fine lines by boosting collagen. A study published in the Journal of Dermatological Research reported that red light promotes collagen synthesis by inhibiting the activity of matrix metalloproteinases, and more than 90% of volunteers experienced improvement in skin wrinkles and roughness after 12 red light treatments with a wavelength of 660 nanometers.
Third, repair damaged cells. Red light therapy has anti-inflammatory and restorative effects and can help repair damaged skin cells. It promotes cell regeneration and repair, accelerates the return of the skin to a healthy state, and reduces the formation of spots. Another study involving 136 volunteers also found that red light treatment reduced the number and roughness of wrinkles and increased collagen density.
Fourth, inhibits melaninization. Red light therapy can inhibit the production and deposition of melanin and reduce the formation of pigmentation and freckles. Red light therapy can regulate pigment metabolism in the skin and block the production and aggregation of melanin, thereby reducing the color and number of spots. In addition, red light has also shown a positive in treating skin diseases such as burns, scars, vitiligo, and psoriasis.
What makes red light therapy a powerful skin anti-aging tool?
As a bright star in modern beauty technology, the red light beauty device has won the favor of countless beauty lovers with its unique characteristics. It provides convenient skincare solutions and stands out in the field of anti-spot beauty with its superior results. So, what are the specific features of the red light therapy device?
- Deeper penetration: Red light therapy's deep-penetrating property stimulates the vitality and regeneration of skin cells and promotes collagen synthesis, skin elasticity, and firmness. It will enable us to enjoy the beauty effect of deep nourishment and repair, leaving our skin rejuvenated and radiant.
The Anti-spot beauty effect is remarkable: The red light beauty devices reduce the formation of dark spots and freckles, even the skin tone to make skin brighter and smoother. With the continuous use of the red light beauty device, existing spots can disappear, quickly restore even skin tone, and make skin more youthful and elastic.
- Safe and non-irritating: The red light beauty device uses non-invasive red light therapy and does not use any chemicals or irritating ingredients. Compared to traditional beauty methods, such as chemical peels, red light therapy is safer and does not cause damage or discomfort to the skin.
- Convenient and comfortable: The red light beauty device provides a convenient and comfortable home skin care experience. We do not need to go to a professional beauty salon; we can operate it at home and do skincare and beauty according to our needs.
Red Light therapy prevents aging-related diseases
The burden of chronic diseases accelerates the process of aging; therefore, anti-aging is equivalent to prolonging life. Previously, red light therapy has been widely used in clinical practice to improve skin aging and treat bone pain. Several studies pointed out the effectiveness of red light therapy in delaying and treating depression, arthritis, stroke, and diabetic foot.
Recently, the latest research by Professor Praveen Arany's Professor Praveen Arany's team at the University at Buffalo in New York showed how photobiomodulation can improve the problem of heart failure in old age, reducing the mortality rate of mice from 57% to 0%. The mice that received red light therapy were significantly healthier as they became older, reflected in improved survival rates and heart problems. This trial further expands and confirms the possibility of red light therapy in delaying cardiac aging and prolonging life.
People are gradually paying attention to the anti-aging application of non-thermal and non-exfoliative photobiomodulation. In particular, red light LED treatment is increasingly used in skin beauty due to its advantages of a safe and gentle treatment process, large beam area, low price, and simple operation. Red light therapy can be applied in the clinic and synergistic at home with portable red light LED device technology to enhance its efficacy, improve the inflammatory response after laser surgery, or accelerate skin wound repair.
