Whether it is Kim Kardashian or Kate Moss, the LED face mask is the newest accessory in a celebrity's skincare routine kit. However, do these sci-fi-looking devices work as well as they promise? According to the experts, yes, with some paramount considerations in mind.
To break down the facts behind LED therapy, we talked to Dr Pragati Gogia Jain, Dermatologist, Apollo Hospitals Lucknow, about how it works, what it actually helps with, and whether your at-home mask can deliver results like a professional treatment.
How LED Therapy Works?
LED therapy is a Low-level, non-thermal light which is used to induce cellular changes via the process of mitochondrial stimulation. In simple words, it alters cellular activity, mostly in the mitochondria, leading to improved healing and reduced inflammation.
According to Dr Jain, “Yes, LED therapy does work, but with specific indications, wavelengths and expectations. LED therapy uses non-thermal, low-level light in various wavelengths to stimulate photobiomodulation. It’s most effective in acne, skin rejuvenation, wound healing, hair regrowth, and psoriasis.”
In-Clinic vs At-Home Devices: What is Better?
LED masks practised at home vs at clinic differ in power and purpose. The professional devices are stronger and hence can be used in the treatment of acne, ageing and loss of hair.
“In-clinic LED devices are more powerful and deliver deeper, faster, and more effective results due to their higher energy output and professional-grade technology. They are ideal for treating conditions like skin ageing. In contrast, at-home LED masks are less intense but safe and convenient for mild concerns or ongoing maintenance,” explained Dr Jain.

LED masks are known to come in variations of colours of the light used. However, they are more than just mere colours. Dr Jain shared different lights’ meanings and the purpose they’re used for. There are different wavelengths for different indications, and they are :
- Red Light (630–660 nm): Best for collagen stimulation, anti-ageing, fine lines, skin repair.
- Blue Light (415–470 nm): Best for acne as it kills C. acnes bacteria, but it may not help inflammation on its own, so often paired with red.
- Yellow/Amber Light (570–600 nm): Best for redness, rosacea, sensitive skin, and dullness.
- Infrared / Near-Infrared (800–850 nm): helps deeper tissue repair, wound healing, and pain relief. It is often used in hair regrowth devices and wound therapy.
LED Masks Work, but With Correct Usage
LED therapy is safe and effective when used properly, but wrong wavelengths, overuse, or low-quality devices can make it useless or irritating,” advised Dr Jain. Think of it like skincare: using the right ingredient, in the right amount, for the right concern, is key.
Dr Jain added, “If you use the wrong wavelength for the condition, e.g., using blue light for anti-ageing won’t help, it doesn’t stimulate collagen, or using red light alone for active acne may not kill bacteria effectively.”
Moreover, dryness or redness, or zero results, can be caused by wrong wavelengths, bad light, or too much light. So, it is important to select and use the devices wisely and act according to instructions.
Tips to Follow While Using LED Masks
- Follow the manufacturer’s protocol: duration, frequency, distance.
- Choose FDA-cleared or clinically tested devices with correct wavelengths.
- Use eye protection if near the eye area, especially with blue light.
- Avoid using it over active infections, open wounds, or suspicious lesions unless medically advised.
