Your Red Light Therapy Device FAQs, Answered:

What is red light therapy?

Red light therapy, otherwise known as RLT, is a noninvasive low-level treatment that uses red and near-infrared light therapy to penetrate deep into the skin, triggering a cellular repair process that can reduce inflammation, accelerate wound healing, and even help reverse visible signs of aging, says Sejal Shah, MD, a board-certified dermatologist and founder of SmarterSkin Dermatology.

Beyond its rejuvenation and anti-ageing potential, this type of light therapy is especially beneficial for those with acne-prone or sensitive skin. Its ability to calm inflammation can lead to fewer breakouts, less redness, and a more even skin tone over time. The light energy may even help fade post-acne marks. And since it doesn’t involve harsh topicals, it’s also a great pregnancy-safe option for people who need to avoid common blemish treatments like retinoids or salicylic acid.


Is at-home red light therapy really worth it?

While red light therapy at home isn’t as powerful as the medical-grade machines found in salons and dermatology clinics, they can still offer noticeable benefits — if you’re consistent and realistic with your expectations.

At-home use takes longer to achieve results, but if you’re patient and follow directions, you can achieve glowing skin on your own schedule, says Margarita Lolis, MD, a board-certified dermatologist at Schweiger Dermatology Group.

Yes, clinical studies on at-home red light therapy are still somewhat limited, but the devices can improve skin issues when used regularly — ideally three to five times per week — and as part of a well-rounded skincare routine that includes cleansing, moisturising, and targeted treatments like hyaluronic acid serums, says Dr. Lolis.

With consistent use, many users begin to see results, such as improved tone and texture, in as little as two months.


Are there any side effects to red light therapy?

Red light therapy isn’t associated with any side effects — even in those with sensitive skin, says Azadeh Shirazi, MD, a board-certified dermatologist and founder of AziMD Skincare.

The one exception? “If you have melasma, then any light therapy can potentially worsen your pigmentation,” says Dr. Shirazi. Look to these dark spot serums, instead.


What precautions should you take when doing using red light therapy devices at home?

Some skincare products contain ingredients that can be photosensitive or reactive when exposed to LED light. As a result, designers often recommend using red light therapy devices on clean, dry skin, free from any makeup, dirt, serum or cream. But these details should also be outlined in the instruction manual for each individual device.

Other precautions include not falling asleep with the device on your body longer than instructed, as this can result in scars and burns. However, most tools have an auto turn-off feature to prevent this.


Is at-home red light therapy safe for your eyes?

At-home LED face masks are generally safe for the eyes, Michael Brusco, MD, FADCS, medical director and surgeon at Brusco Vision, tells Glamour. If your mask feels really bright or is creating a glare, it’s generally more annoying than harmful, he says.

For those who have more sensitive eyes or have lingering concerns, look for a mask that offers eye protection, like our top pick listed above. You can also use eye drops to lubricate the eyes immediately following red light treatment, since bright light can cause dry eyes, says Dr. Brusco.


What should you look for in a red light therapy device?

  • FDA clearance: All of the red light therapy devices on our list are FDA-cleared—an attribute that both the American Academy of Dermatology, as well as the dermatologists we spoke to, said was highly important for both safety and efficacy.
  • Design: Red light devices come in many shapes and forms, from masks (structured or flexible silicone) to handheld wands to panels (some of which are full-body) to headbands or caps for hair loss. For your face, we found that masks are the most convenient and comfortable, but we did appreciate the versatility of wands and panels, since they can be directed at your face or your body.
  • Light modes: Start by looking for a red light device that operates at 620 to 750 nanometers for anti-inflammatory and anti-ageing qualities, and collagen production. If you have other skin care concerns, like acne, you may want to look for a device that has additional modes. The two most popular are blue light therapy (405 nm to 420 nm), which does not penetrate as deeply but has antimicrobial properties to target acne-causing bacteria, and infrared-light therapy (760 nm to 1400 nm), which can help reduce redness and even out dark spots and hyperpigmentation, or skin conditions like rosacea.

Can red light therapy help hair growth?

Low-level laser therapy (LLLT), like red light, can stimulate hair follicles by increasing ATP production (a.k.a. your cell’s “energy”), reducing inflammation, and helping prolong the hair-growth phase, says Alan Bauman, MD, a board-certified hair-restoration physician at Bauman Medical.

“It’s well supported by research and is one of the most effective noninvasive tools for hair regrowth.” Clinical studies echo this sentiment, suggesting that red-light therapy at wavelengths of 650 nanometers can support hair growth for some people.


How often can you use a red light therapy device?

Determining how often you should use your red light therapy device fully depends on the results you’re looking for. Most devices suggest biweekly use, while some, especially those that promote hair growth, recommend daily treatments. If you’re unsure about how often you should use yours, it’s best to check with your board-certified dermatologist or trichologist.

It’s lightweight, mostly cordless (with a small remote), and easy to wear while multitasking. “It fits very comfortably — I can even lie down on my couch wearing it,” says Glamour’s Calle.
