- 0:28Can red light therapy grow hair and slow down the the
- 0:32signs of aging as well as help acne?
- 0:36These are the questions we asked dermatologist Dr.
- 0:39Lauren Kole, who joins us with her advice from
- 0:43her office at UAB.
- 0:47Dr. Lauren Kole, thank you so much for
- 0:51joining us from UAB. It's my pleasure. Dr.
- 0:54Kole, as a dermatologist, and you wear many hats
- 0:58at UAB, what information can you tell us
- 1:01about red light therapy? Therapy? We're hearing that term.
- 1:05Yes, red light therapy has been very popular in
- 1:09recent months to years. There's devices
- 1:12that are available in physicians' offices, as well as at-home
- 1:17devices. It works by a process called photobiomodulation.
- 1:21So, it targets signs of aging, such as age
- 1:25spots, sagging skin, redness,
- 1:28as well as it treats medical conditions such as acne and
- 1:32hair loss. So what does the research show
- 1:36as far as effectiveness? So the research shows that it works by
- 1:39stimulating cells to increase their collagen production,
- 1:43reduce inflammation, and kind of speed along the wound healing
- 1:47process. And it's been shown mostly with the in-office
- 1:51devices that we have that it can really help
- 1:54improve patients' signs of aging,
- 1:58as well as, like I mentioned, treating acne or hair loss. So are you
- 2:02talking about red light therapy actually regrowing
- 2:05hair? Yeah. So they showed that red light
- 2:09therapy, in this instance it's called low-level light therapy,
- 2:14stimulates hair growth in patients with androgenetic
- 2:17or kind of age-related hair loss, both men and
- 2:21women. And they show it's about the equivalent
- 2:24of topical minoxidil, which is the ingredient
- 2:29that's found in over-the-counter Rogaine. So could it be even safer
- 2:33than the chemical? Potentially. There are some limitations
- 2:37on patients where it might not be appropriate for them, but yes.
- 2:41Dr. Cole, what is the safety profile of
- 2:44red light therapy? There are devices that are meant to be
- 2:47used by a medical professional and those that are designed to
- 2:51be used at home. Most of the at-home devices
- 2:56have LED light, and in the short term,
- 3:00they do appear to be safe. They have not been shown to
- 3:03increase risk for skin cancer. And there are devices
- 3:07on the market that have been FDA cleared for safety.
- 3:12If there are listeners who have these devices at home,
- 3:15should they be wearing protective eyewear? And should this
- 3:19be confined to people of a certain age?
- 3:22It's really not indicated maybe for mostly of our younger
- 3:26population unless they're treating something such as acne. But really most
- 3:30of the research, like I mentioned, is more in treating kind of signs of aging
- 3:34and hair loss, which wouldn't necessarily be applicable to our younger population.
- 3:37Patients. In terms of eye protection,
- 3:41yes, eye protection is generally recommended,
- 3:45but I would just follow whatever the instructions are included with
- 3:48their at-home device. But when we do do the treatments in office,
- 3:52eye protection is worn. In the cases
- 3:55of acne or rosacea, these are
- 3:59pesky conditions. How can red light therapy help?
- 4:04It really should be more as adjunct or complementary
- 4:08therapy to a well-established medical
- 4:12treatment plan that's decided upon between the patient and their dermatologist.
- 4:17So I wouldn't rely on it alone to treat acne
- 4:20or rosacea, but it could complement the response we see
- 4:24from medical therapy. And are these 2
- 4:28conditions curable? I would say they're manageable,
- 4:31not necessarily curable. What advice can you
- 4:35give us about preventing skin cancer? Yeah, so we
- 4:39always want to make sure that we're being very careful with our sun protection.
- 4:44The use of sunscreen, we want to look for one that's
- 4:48labeled broad spectrum, so that means it covers UVA and
- 4:51UVB wavelengths. And you also want to
- 4:56look for a sunscreen that's SPF 30 or higher to make
- 4:59sure you're getting the most of your sun protection. And since
- 5:04we live in what could be called the Sun Belt, these southern
- 5:08states, do people of all ages,
- 5:10including young children, need to protect against skin cancer
- 5:14with this SPF 30? Yes,
- 5:17especially young children really need to practice their good
- 5:21sun protection because it's that repetitive exposure
- 5:26to these harmful rays that can start at a young age that may
- 5:30lead to skin cancers down the road. Dr. Cole, you are also
- 5:34an expert on psoriasis. What can you tell us about
- 5:38that, and can it be cured or simply managed? Yeah,
- 5:42psoriasis is also a chronic disease that we can't necessarily
- 5:46cure, but we can manage it. And nowadays we have
- 5:49very, very good drugs that can essentially
- 5:53clear a lot of patients' skin with them that
- 5:57are very safe and well tolerated. So if anybody is struggling
- 6:02with managing psoriasis, definitely recommend them seeing a dermatologist
- 6:07to discuss those options. And back to the red light therapy,
- 6:11if any of your listeners have a home device,
- 6:15how often should they safely use it, or can they
- 6:19safely use it? Really, you should follow
- 6:22what instructions come with the device because there is quite a
- 6:26variability of what's available on the market. Just like with the
- 6:29eye protection recommendations, just follow what directions it
- 6:33says on the device. There are some devices that are designed
- 6:37for hair loss or a device that's designed for aging or a device
- 6:41that's designed for acne. So, making sure that you're choosing a device
- 6:45that's properly designed for what you wish to treat.
- 6:48I have a few precautions that I would say with patients self-treating at
- 6:52home. Patients may be on medications that
- 6:56make them more sensitive to light exposure. So, just making sure that
- 7:00they're not taking anything that may interfere with the light therapy.
- 7:04Some patients may have skin conditions that are sensitive to light,
- 7:08such as lupus, so making sure they clear that with their doctor
- 7:11before they use a device like this. And then lastly,
- 7:15some patients of darker skin tones,
- 7:18sometimes pigmentation can worsen with light exposure. So,
- 7:22just making sure that those patients are using
- 7:25these with caution. When should people see a dermatologist?
- 7:30Anytime they have any concern, like those conditions
- 7:35we already mentioned, lesions that they're concerned about and would like evaluated,
- 7:39they always are very welcome to reach out to a dermatologist
- 7:44to make an appointment and have those things evaluated.
- 7:47Generally, we do recommend annual skin exams in
- 7:51patients, you know, in their 30s and 40s and older, just because the rates
- 7:55of skin cancer are quite high in the United States. And then, if you have
- 7:59any concerns, we're always happy to evaluate the patient or provide
- 8:03reassurance. As a dermatologist, what do you wish
- 8:07your listeners would do or know more about?
- 8:11Practice as much preventative care as they can.
- 8:15We always preach good sun protection and sun protective
- 8:19clothing, and if we really followed it, we would
- 8:23prevent a lot of these skin cancers and other age-related changes
- 8:27down the road. For melanoma, we like to counsel the ABCDEs.
- 8:33So when you're looking at a mole or a pigmented lesion, you're looking
- 8:37for warning signs such as asymmetry,
- 8:40irregular borders, multiple colors or unusual colors,
- 8:45diameter, so a large lesion, and then one that's
- 8:49changing. So those are kind of key things to look for when we're looking for
- 8:53maybe melanoma risk. And then other types of skin cancers
- 8:57may not have color on them like a melanoma can.
- 9:01And so, you're looking for new kind of red growths, ones that
- 9:05are painful or itchy or bleeding or just
- 9:09not healing or not resolving. It's always good
- 9:13to come in and have your dermatologist evaluate it. Dr. Kole, I want
- 9:17to thank you for your words of advice today, and I want to thank you
- 9:21for your visit here at Troy Public Radio from UAB.
