Erase Wrinkles, Heal Acne and Firm Skin: Is LED Light Therapy Too Good to Be True?
From minimising breakouts to stimulating collagen, two doctors weigh in on the pros and cons of LED masks.
If you've been on Instagram lately, then I'm sure you'll have come across a photo of someone wearing one of those futuristic-looking LED face masks. In fact, I've been seeing these high-tech beauty tools cropping up more so than ever lately, with lots of people raving about the positive effects that LED can have on your skin. But these masks aren't cheap. In fact, some can set you back over £1000, and it's safe to say I receive lots of questions about whether or not they are actually worth their money.
As a beauty editor, I'm lucky enough to speak to industry experts daily, so I decided to reach out to Dr Raj Arora, NHS doctor and key opinion leader for Foreo, and Dr Maryam Zamani, oculoplastic surgeon and founder of MZ Skin, to answer your questions once and for all, including how these at-home masks actually work.
What Is LED Light Therapy?
First things first, what actually is LED light therapy? According to Dr Arora, LED stands for light-emitting diode and is a non-invasive, pain-free treatment that uses light to address skin concerns. "Essentially, LED wavelengths enter the skin’s layers and stimulate the natural healing mechanisms," she explains.
Dr Zamani says that LED has been used for over 30 years to heal the skin and stimulate collagen and elastin. "LED therapy uses light from the visible spectrum to stimulate the cellular response to regenerate through a process called photobiomodulation. Shorter wavelengths target superficial skin whilst longer wavelengths penetrate more deeply." The light essentially recharges the cells' energy battery, and the skin is then able to utilise the energy as fuel to repair and rejuvenate damaged cells, boosting the skin's natural repair process.
There are different ways that you can try this treatment out; either at an aesthetic clinic or at home by using an LED face mask.
Types of LED Light Therapy
People often ask me which skin concerns LED therapy can help with. The great thing about this treatment is that you can choose from a range of light colours and wavelengths to help tackle specific things, such as fine lines or acne. According to Dr Zamani, red and blue light are the most commonly used; however, to give you a better understanding, Dr Arora has broken down each light and its benefits below:
1. Red Light
This light stimulates the production of collagen and elastin, which can help to firm and lift the skin. Dr Zamani adds that it can also reduce inflammation, heal blemishes and help improve scarring.
2. Blue Light
Blue light can help to target acne-causing bacteria, in turn minimising future breakouts whilst also reducing inflammation and speeding up the skin's recovery time. LED masks that contain blue light are thought to be great acne treatments.
3. Green Light
Although it's not as commonly used as red and blue, green light can help to even out skin tone, tackle dark circles and brighten dull complexions.
4. Yellow Light
Yellow light can ease redness and swelling from things such as sunburn, rosacea or inflammation.
5. White Light
White light can penetrate deeply into the skin and can help activate the natural renewal of skin cells.
Who Should Avoid Using LED Light Therapy?
Before thinking about trying an LED facial or investing in an at-home mask, it's important to check whether this treatment is safe for you. Dr Zamani says that although everyone can benefit from light therapy, it isn't recommended—either at home or in a clinical setting— for someone who suffers from seizures or epilepsy, due to the bright lights. She also advises that anyone suffering from migraines or eye conditions or taking certain medications should give this treatment a miss. Most devices also advise against usage for pregnant or breastfeeding women.
If you're wondering whether you can overuse your LED mask at home, Dr Arora says not to worry. "Generally speaking, you cannot really 'overuse' an at-home LED mask if you are using it correctly and sensibly. The longer the exposure to LED therapy, the better the outcome, unless skin is sensitised or you are using active skincare ingredients that may make the skin more prone to sensitivity." She explains that LED light therapy does not contain UV light and therefore does not carry the same risk of burns.
How to Use an LED Face Mask at Home
If you're keen to give LED therapy a go at home, it's best to invest in a mask with the appropriate light settings for your skin concerns. To get the most out of your investment, Dr Zamani advises following the manufacturer's instructions, unless you've been told by your doctor or dermatologist to use the device differently. "I would also recommend building up [the duration of treatment] using the device to [increase] tolerance and reduce the risk of skin feeling dry or irritated," she explains. She also advises consulting your doctor or dermatologist if you're using medical-grade skincare or active skincare ingredients to make sure that these won't cause any harmful reactions when combined with LED therapy.
Is an At-Home LED Face Mask Worth It?
So, now that you know everything about LED therapy, you might be asking yourself, is it worth buying an at-home mask? In my opinion, an LED face mask is a worthwhile investment if you're looking to tackle specific skincare concerns. The treatment has a wide range of benefits, and if used consistently over time, can make significant improvements to your skin.
Although it might seem like a lot of money straight away, when you compare the price of an at-home mask to an in-clinic treatment, it's a lot more cost-effective. As summarised by Dr Zamani, "I love the skin-boosting effects of LED and think it is the best at-home device that can be done safely."

When Who What Wear UK beauty editor, Eleanor Vousden, put the Beauty Pie LED Mask to the test, she was amazed by the results (just look at the before and after pictures). "After two months of use, I can see a visible improvement in my skin's redness, my acne scarring has improved and my skin looks glowier than before treatment," she says.
The Currentbody LED mask is a slightly more affordable option for those wanting to try an at-home device. If you think you've heard of it before, that might be because you spotted it in the Netflix show Emily in Paris. If it's good enough for Lily Collins, then it's good enough for us.
