LED technology has been widely used in medical settings to address various skin conditions such as eczema, mild to moderate acne, psoriasis, and sun damage. Now, the at-home LED skincare market is rapidly expanding, with masks and devices ranging in price from affordable to high-end luxury options.
These devices use light-emitting diodes (LEDs) to stimulate skin cells through repeated exposure. Many manufacturers claim that LED masks can help reduce acne scars, sun damage, and fine lines, but how effective are they?
The LED skincare industry is projected to reach a global value of £600 million by 2032, nearly doubling the worth of popular hair styling technologies. According to dermatologist Dr. Jonathan Kentley, LED therapy works by allowing the skin to absorb light energy, triggering cellular changes through a process called photobiomodulation (PBM).
"This promotes the formation of new blood vessels and skin cells while increasing collagen and elastin production," Dr. Kentley explains. "PBM also has anti-inflammatory properties and can reduce excess oil, making it beneficial for acne treatment."
While PBM has been studied extensively, experts agree that more clinical trials on human subjects are needed to fully understand its long-term effects. LED light therapy was initially researched by NASA in the 1990s for its potential in cell regeneration. Since then, medical-grade LED treatments have been widely used by dermatologists. However, at-home LED masks, which have been available for about five years, differ in strength, number of bulbs, and proximity to the skin compared to professional devices.
Are At-Home LED Masks Effective?
Dr. Justine Kluk, a dermatologist specializing in acne treatment, acknowledges that at-home LED masks sound promising but cautions against exaggerated claims. "There are no large-scale clinical trials comparing at-home masks to professional devices used in clinics or hospitals," she states. "Without long-term studies on a significant number of users, we can't be completely confident in their effectiveness."
Skincare remains a dominant segment of the beauty industry and continues to grow, driven by younger generations influenced by social media trends. Many consumers are drawn to LED masks due to their visually striking appearance and ease of use. Dr. Kluk notes that since the pandemic, interest in at-home skincare treatments has surged.
"Seeing people wearing red LED masks while watching TV sparks curiosity, which helps boost sales," she adds. "In my practice, I've noticed a rise in patients asking about LED masks."
Social media is flooded with testimonials from users claiming noticeable skin improvements after using at-home LED masks. Natalie O'Neill, a skincare content creator, started using one out of curiosity rather than to treat a specific skin condition.
"After a few weeks, I saw changes in my skin, particularly in preventing breakouts and evening out my skin tone," she shares. However, she emphasizes that she integrates the mask into a consistent skincare routine and does not rely on it as a standalone treatment.
Laurence Newman, CEO of CurrentBody, a leading manufacturer of at-home LED masks, believes that non-invasive skincare solutions are gaining popularity. "More people, especially women, are looking for alternatives to Botox and fillers," he says. "Our masks use the same technology as medical-grade devices, ensuring effective light wavelengths."
What to Consider Before Buying an LED Mask
Dr. Kentley reassures that PBM is generally considered safe, even at high intensities, and is unlikely to damage skin cells. However, he emphasizes the need for more standardized research. "While there have been various studies on PBM for dermatological conditions, many were small-scale and funded by manufacturers, making it difficult to draw definitive conclusions."
For those interested in purchasing an LED mask, he recommends choosing one with EU safety certifications and a high density of LED bulbs to ensure adequate energy absorption. Dr. Kluk also advises consumers to have realistic expectations.
"I don't want to discourage anyone intrigued by the technology, but it's important to understand that LED masks are a significant investment. They may complement a good skincare routine, but for more severe conditions like acne, professional treatments and prescribed regimens are often necessary for optimal results."
