Is LED light therapy safe for your skin? Dermatologists answer key questions

Ask a skincare enthusiast what is the secret behind their glowing and flawless skin, chances are they might say, LED light therapy. This one, as we know it, is unlike any other face masks we have been using for optimal care of our face skin.

This new tech-driven skincare trend took the internet by storm last year after many international celebrities posted pictures of themselves that showed bright neon lights emanating from a face-covered robot-like mask.

Dermatologists wave a green flag, however, you must consider a few factors before making a purchase.

Rise in popularity of this skincare trend
Dr Meghna Mour, aesthetic dermatologist, cosmetologist, trichologist, laser specialist and the founder of Skuccii Supercliniq says, "The LED light therapy originated when NASA used it to promote wound healing in astronauts. This propelled the finding that it helps in skin regeneration. Originating from NASA's research for plant growth, LED therapy gained popularity in skincare due to its non-invasive nature and effectiveness."

LED or Light Emitting Diode therapy is a non-invasive treatment that utilises a specialised device emitting specific wavelengths of light. These wavelengths target different skin concerns by penetrating the skin and stimulating cellular processes. This technology, however, is not new. It has been used by experts for professional treatments at skin clinics for years.

Further, Dr Gitika Sanodia Biyani, dermatologist, cosmetologist, and trichologist at Dr LH Hiranandani Hospital adds, "LED light therapy originated in the medical field for wound healing and expanded into skincare due to its ability to address various skin concerns. Its popularity grew as more people sought non-invasive treatments for anti-ageing, acne, and overall skin rejuvenation. Its expanding use in diverse skin concerns contributed to its widespread acceptance and integration into contemporary skincare routines."

Likewise, Dr Rinky Kapoor, consultant dermatologist, and dermato-surgeon, The Esthetic Clinics, says, "Recognising the innumerable benefits the LED face mask light therapy offers, celebrities and beauty influencers began using the device. This too led to the rise in popularity of this skincare trend."

Buying the face mask
"Whether you should invest in an LED light therapy face mask depends on your specific skincare needs and concerns," says Biyani.

The face mask targets any skin issues using different lights installed. Those who have issues such as acne, psoriasis, pigmentation or uneven skin tone, can yield benefits from using this mask.

There are mainly four lights installed in the mask:
1. Red light for anti-ageing: This colour helps stimulate collagen production, and reduces fine lines and wrinkles thereby reducing signs of ageing and may also delay the process, reducing fine lines.
2. Blue light for acne treatment: This targets acne-causing bacteria aiding in the prevention and management of acne breakouts.
3. Amber light for inflammation reduction: Amber light helps in soothing the skin by reducing inflammation.
4. Green light for pigmentation: This helps reduce the appearance of pigmentation or hyperpigmentation.

The overall result is an improvement in skin texture, a reduction in inflammation, and various therapeutic effects. This treatment is known for its versatility, addressing multiple skincare issues with minimal risk and downtime, making it an appealing option for those seeking gentle yet effective skin rejuvenation.

The LED face mask light therapy might look like lavish spending but it's not. It is pretty affordable. However, the cost of each mask will differ depending on the brand and its features. Kapoor says, "Entry-level masks can be affordable, but high-end ones with more features may be costly."

The cost of a basic LED face mask starts somewhere at Rs 1,500 and goes up to Rs 43,000.

Before you make a purchase, it is important to look at devices from various brands. Speak to a few people who have already used the mask to understand how their experience was. If purchasing online, always read product reviews to gain more clarity.

Further, always check if the device is safety-approved by bodies like the FDA. Check the quality of the brand. It wouldn't be wise to go for any brand selling these masks at cheaper rates as this is a skincare product.

You must also circle on a mask that best meets your skin's requirements. Many might simply have acne breakouts and might not need a mask that also resolves pigmentation issues. In such a case you can pick a mask offering only those features that you require. This way you can also cut down on the cost.

These are some ways to pick the right mask that suits your skin needs and fits your budget.

Risk factors
As a lot of us might fret about using the mask radiating bright light Mour says, "When used correctly and with guidance from a dermatologist, LED light therapy face masks are safe for use at home." This said, she also states, "LED face mask is ultimately a medical grade device and should be done under doctor's supervision. It's always preferable to seek such therapies in aesthetic medical centres."

Biyani too is assertive of the benefits the face mask offers. "LED face mask light therapy is safe if you follow the instructions. These masks use low-level light, which is generally low-risk when used correctly."

While the mask is largely safe to use, it might have adverse effects on some.
1. It might cause strain to the eye and also lead to headaches.
2. Repeated use may cause dryness and burning of skin and eyes.
3. It can lead to developing signs of insomnia.
4. The face mask may also cause mild visual side effects.
5. Overuse of the mask can also lead the skin to become sensitive.

How to use the mask
To use LED face mask correctly, follow the instructions carefully mentioned in the package. Use it for 10-20 minutes, two to three times a week, focusing more on regular use than doing it often.

The best time to dive into this skincare is after cleaning your face. You can use it during day or night, whichever suits you. Following these steps makes sure it works well and is safe for your skin.

Once you are done, make sure to apply a non-irritating moisturiser to further soothe the skin. Along with this, one must never discontinue their regular application of sunscreen during the day. This is essential to protect the skin.

Common misconceptions
To truly utilise the potential of LED face mask light therapy, it's necessary to get rid of certain common misconceptions.

Some people think using an LED light therapy device will give instant results, but that's not true. It takes time to see improvements, so you need to stay patient and consistent for the best results.

Another misconception is thinking that LED therapy can replace all your other skincare habits. While it's helpful, it works better when combined with other skincare habits like cleaning and moisturising your skin. Using it as part of a complete skincare routine gives you the best results and makes sure you're taking care of your skin the right way.

The mask might not be suitable for all
Pregnant women should refrain from using LED light therapy devices. The effects of this therapy on pregnancy are yet not known so it is best to avoid it to ensure safety.

Further, those whose skin is sensitive to light or those on certain medications should try to avoid going ahead with using the device. If at all you wish to give it a try, it is best to seek advice from your dermatologist to ensure safety and efficacy for your specific situation. This can help you avoid any negative effects of the therapy.

Alternatives to using the LED face mask
There are other things you can do for your skin instead of using LED light therapy if you are still apprehensive.

You can try chemical peels, which help make your skin tone better, or microdermabrasion, which makes your skin feel smoother. Laser therapy too is good for wrinkles and pigmentation. It's important to talk to a professional to figure out which one is right for your skin.
