BLUEMINATION In LED light therapy, blue light prevents acne by terminating bacteria that causes skin inflammation

Some come in masks, some in wands. No, we’re not talking about Halloween costumes. We’re talking about LED light masks. We’ve all seen our favorite celebrity using LED light as part of their regimen. And why not? Some say it’s the closest alternative to a derma visit that can address issues from acne to aging. But what is LED light anyway? What are its benefits? And more important, does it deliver its promise?

Since the ancient times, people have already known light’s healing quality. In the last few decades, LED light therapy, once known as photo therapy, has expanded its use from pain management and wound healing to other types of inflammation. It has been used by athletes, the military, and now, even you and me! Fast forward to today, LED light therapy is now also being used to treat skin conditions, boasting of myriad benefits, from acne reduction and skin rejuvenation to anti-aging. It is even available as a portable device we can use at home.

LED light therapy has different colors in various wavelengths that address specific skin conditions.

LED light therapy doesn’t emit harmful UV light, doesn’t hurt or burn the skin, and is suitable for all skin types and colors. But before you try a session in the clinic or buy your own device, listen to your dermatologist first.

RED – For those suffering from stubborn acne scars and spots, this wavelength can address that and more. It also stimulates collagen production, as well as help fade wrinkles. 

BLUE – Got acne? This one’s for you. It kills acne-causing bacteria and keeps them at bay.

AMBER – Sun-loving folks, here’s what can save your skin from damage. It also offers anti-aging benefits as it helps fade fine lines and wrinkles as well.

GREEN – This color evens out the skin tone, improves skin complexion, and helps in balancing the skin’s oil production.

LET YOUR SKIN SHINE Doctors guarantee that LED light therapy is safe

The good news is, LED light therapy doesn’t emit harmful UV light, doesn’t hurt or burn the skin, and is suitable for all skin types and colors. But before you try a session in the clinic or buy your own device, listen to your dermatologist first. This is because LED light therapy is not for everyone, especially those who have eye problems, those who have photosensitivity, or those taking oral medication that can cause skin sensitivity, like isotretinoin. Also, LED light therapy alone is not enough to treat your skin condition, so make sure to get a proper treatment plan from your dermatologist before trying this out.

So is LED light therapy for real? Studies have shown promise on its effects in certain skin conditions as mentioned above. There’s a difference, however, between an at-home device and an in-office machine. If you’re opting for a home device, it can definitely complement your skin care regimen, but with its lower power, you will need more sessions to be able to see results. This is why it cannot replace the efficacy and precision of LED light therapy machines in the dermatologist’s office. These machines emit powerful wavelengths in larger panels under controlled settings, and are therefore much more effective in achieving results in a shorter time. Of course, the uses of LED light therapy may not end here. Research continues to explore and prove its effectivity not just for the skin but for other health conditions as well.
