LED light therapy can help you achieve your skincare goals – VOGUE India
The venture of LED light therapy in the skincare market isn’t new and evidently they’re here to stay, if our Instagram feeds are anything to go by. While earlier they were under the purview of professional skin clinics, the pandemic has brought them right into our homes. “Due to the lockdown, there was lack of accessibility to professional clinics, which is what paved the path for these ‘plug and play’ devices,” shares Vibhuti Arora, face yoga expert and founder, House of Beauty. So, while your skincare routine may have graduated from just a night cream, to including rollers and now an LED light therapy mask with the right light based on your skin concern can do wonders.
The connection between LED therapy and skin
LED light therapy in skincare can be traced back to the early 1900s when inventor and engineer Nikola Tesla created the violet ray generators to treat skin wounds. While these eventually phased out, in the 1980s, NASA accidentally discovered how red light could heal its astronauts’ skin. Speaking about the science behind it, Dr. Jaishree Sharad, dermatologist and author says, “The treatment uses varying wavelengths of light that are absorbed by light-sensitive molecules inside the skin cells, creating a positive response.” Here’s how you can use LED therapy to address various skin concerns.
According to Arora, LED therapy is effective in treating acne. “These lights are at a premeasured frequency. The blue and purple lights are antibacterial—they penetrate beyond the first two skin layers and help with faster drying of acne.” Dr. Sharad further points to studies that prove that blue light can kill P.acnes or acne-causing bacteria. She recommends using blue light (405–420 nm) for 8–20 minutes twice a week to reduce inflammatory acne (pustules and small cysts), blackheads and whiteheads.
“When used on wounds on time, they heal well thus preventing scars,” says Dr. Sharad. Arora suggest a combination of red, green and white LED for scars. “Red is for boosting collagen; white is for cell regeneration and green is for wound healing. Irrespective of the concerns, I recommend using a mask for 20 minutes if you’re using it twice a week, or 15 minutes if you’re using it thrice a week.”
Yellow light is effective for treating concerns on the surface of the skin—pigmentation, sun spots and freckles. However, Dr. Sharad does remind us that while LED can reduce epidermal pigmentation, it has no effect on dermal or deep pigmentation.
Signs of ageing
“Red LED stimulates fibroblast proliferation, collagen synthesis and growth factors which results in tighter skin and improvement in sagging and wrinkled skin,” adds Dr. Sharad. She further points out that home devices deliver significantly less power as compared to medical-grade units. “However, in some cases, home units may be used along with dermatologist-provided treatment to address specific areas of concern.” Arora, too reiterates that one can’t expect miracles by only using LED therapy. Good skin after all is the sum total of a healthy lifestyle coupled with healthy skincare habits.
