Have you ever heard of red light therapy? If not, you might be missing out on a natural and effective way to enhance your beauty and wellness. Red light therapy is a treatment that uses low-level wavelengths of red or near-infrared light to stimulate cellular processes and promote healing. In this blog post, I will explain what red light therapy is, how it works, and what benefits it can offer for your skin and hair.
What is red light therapy?
Red light therapy (RLT) is also known as low-level laser therapy (LLLT), low-power laser therapy (LPLT), photobiomodulation (PBM), or phototherapy. RLT is a treatment that uses low wavelength red light to improve skin appearance, reduce wrinkles, scars, redness, and acne. It is also being investigated for treating a wide array of health conditions.
It is a non-invasive, painless, and safe procedure that involves exposing your skin to a device that emits red or near-infrared light. RLT is thought to work by acting on the “power plant” in your body’s cells called mitochondria. The light penetrates the skin and reaches the cells, where it is absorbed by the mitochondria, the “powerhouses” of the cells. This stimulates the production of adenosine triphosphate (ATP), the energy molecule that fuels cellular functions. With more energy, other cells can do their work more efficiently, such as repairing skin, boosting new cell growth, and enhancing skin rejuvenation. As a result, red light therapy can enhance the health and performance of the cells, leading to various benefits for the skin and hair. While there is a lot of ongoing research and publication of small studies, the full effectiveness of RLT has yet to be determined. However, many researchers say more clinical trials are needed to confirm its effectiveness as a treatment. If you’re interested in RLT, ask your healthcare provider if this is an option for your skin issue.
How does red light therapy work for the skin?
The skin is the largest organ of the body and is constantly exposed to environmental stressors, such as UV rays, pollution, and toxins. These factors can damage the skin cells and cause signs of aging, such as wrinkles, sagging, dullness, and hyperpigmentation. Red light therapy can help reverse some of these effects by boosting the natural repair and regeneration processes of the skin. The benefits of RLT include reducing wrinkles, scars, redness, and acne. It is also touted to treat other medical conditions. RLT appears to be safe and is not associated with any side effects, at least if used short-term and as directed. This therapy is not toxic, not invasive, and not as harsh as some topical skin treatments. Unlike the cancer-causing ultraviolet (UV) light from the sun or tanning booths, RLT doesn’t use this type of light.
More ways that red light therapy can improve the skin are:
- Stimulating collagen production. Collagen is the main structural protein of the skin that gives it firmness, elasticity, and smoothness. As we age, our collagen levels decline, leading to wrinkles and sagging. Red light therapy can increase the synthesis of collagen by activating the fibroblasts, the cells that produce collagen. This can help reduce the appearance of fine lines and wrinkles and improve the texture and tone of the skin.
- Increasing blood circulation. Blood carries oxygen and nutrients to the skin cells, as well as removes waste products and toxins. Red light therapy can enhance the blood flow to the skin by dilating the blood vessels and increasing the formation of new capillaries. This can improve the delivery of oxygen and nutrients to the skin cells, as well as the removal of waste products and toxins. This can result in a brighter, healthier, and more radiant complexion.
- Reducing inflammation. Inflammation is the body’s natural response to injury or infection, but it can also cause damage to the skin cells and tissues. Red light therapy can modulate the inflammatory response by reducing the production of pro-inflammatory cytokines, the molecules that trigger inflammation. This can help heal the skin and prevent further damage. Red light therapy can also reduce the activity of acne-causing bacteria, which can cause inflammation and breakouts.
- Enhancing wound healing. Wounds, such as cuts, burns, or scars, can impair the integrity and appearance of the skin. Red light therapy can accelerate the wound healing process by stimulating the proliferation and migration of skin cells, as well as the formation of new blood vessels and collagen. This can help close the wound faster and reduce the risk of infection and scarring.
How does red light therapy work for the hair?
The hair is composed of keratin, a protein that is produced by the hair follicles, the tiny structures under the skin that grow the hair. The hair follicles have a life cycle that consists of three phases: anagen (growth), catagen (transition), and telogen (resting). The length and quality of the hair depend on the duration and activity of the anagen phase. However, various factors, such as genetics, hormones, stress, aging, and medical conditions, can disrupt the hair cycle and cause hair loss or thinning. Red light therapy can help restore the hair cycle and promote hair growth by:
- Stimulating the hair follicles. Red light therapy can increase the blood flow to the scalp and deliver more oxygen and nutrients to the hair follicles. This can activate the dormant hair follicles and prolong the anagen phase of the hair cycle. This can result in more hair growth and increased hair density and thickness.
- Preventing hair loss. Red light therapy can inhibit the production of dihydrotestosterone (DHT), a hormone that shrinks the hair follicles and causes hair loss. By blocking the action of DHT, red light therapy can prevent the hair follicles from miniaturizing and entering the telogen phase prematurely. This can reduce hair shedding and maintain the hair volume and coverage.
- Improving hair quality. Red light therapy can enhance the health and strength of the hair by increasing the production of keratin and other proteins. This can improve the structure and elasticity of the hair shaft and prevent breakage and split ends. Red light therapy can also increase the melanin production, the pigment that gives the hair its color. This can prevent premature graying and fading of the hair.
How can you use red light therapy at home?
Red light therapy is a simple and convenient treatment that you can do at home. There are various devices that you can use, such as:
- LED masks. These are wearable devices that cover the face and emit red light. They are ideal for treating skin issues, such as wrinkles, acne, and scars. You can use them for 10 to 20 minutes a day, depending on the device and your skin condition.
- LED combs. These are handheld devices that have LED lights attached to the teeth of the comb. They are designed for treating hair loss and stimulating hair growth. You can use them for 10 to 15 minutes a day, depending on the device and your hair condition.
- LED helmets. These are wearable devices that cover the scalp and emit red light. They are also effective for treating hair loss and stimulating hair growth. You can use them for 20 to 30 minutes a day, depending on the device and your hair condition.
- LED panels. There are different types of red light therapy panels, depending on the size, power, wavelength, and features. Some panels are designed to cover the whole body, while others are focused on specific areas, such as the face or the scalp. Some panels offer multiple wavelengths, such as 660nm (red) and 850nm (near-infrared), which can be used separately or together. Some panels also have additional features, such as dimming, pulsing, timers, and digital controls.
Before using any red light therapy device, make sure to read the instructions carefully and follow the recommended frequency and duration of use. Also, consult your doctor before starting red light therapy, especially if you have any medical conditions or are taking any medications that may affect your sensitivity to light.
Which Red Light Therapy Machine Do I Use and How to Use it
I have been using the Hooga Pro HG300 red light therapy machine for about a month now and I am very impressed with the results. I use it mainly for my face and hair, as I wanted to improve my skin health and appearance while also regrowth the hair on the my scalp and hairline. I have noticed a significant improvement in the texture, tone, and elasticity of my skin, as well as a reduction in fine lines and wrinkles. Moreover, my skin feels smoother, firmer, and more radiant. However, the biggest change has been in my babyhairs near my hairline. It’s been a smooth scalp in that area for almost a decade, and yet I’ve suddenly sprouted a new hairline in 30 days!
The Hooga Pro HG300 is a high-quality, powerful, and versatile device that offers both red and near-infrared light at clinically proven wavelengths of 660nm and 850nm. It has a high irradiance of 109 mW/cm² at 6 inches, which means it delivers a lot of light energy to the skin and cells. It also has a 60-degree beam angle, which means it covers a large area of the body. It comes with an adjustable stand that allows you to position the device at different angles and heights. It also has a built-in cooling fan that prevents overheating and noise.
The device is very easy to use and operate. It has a digital control panel that allows you to choose between red, near-infrared, or both. It also has a modular design, which means it can be connected to other panels in the Pro series to create larger, customized setups. The device is also very durable and reliable, with a 50,000-hour lifespan and a 3-year warranty.
The only downside of the device is that it is not very portable, as it is quite heavy and bulky. It also does not come with a full hanging kit, as it is primarily designed to be used as a tabletop stand. However, these are minor issues compared to the benefits and features of the device.
Overall, I am very happy with the Hooga Pro HG300 red light therapy machine and I would highly recommend it to anyone who wants to improve their skin and hair health and appearance. It is a great investment for your beauty and wellness, and it is worth every penny. There are plenty of RLT machines on the market, but not all of them will have the level of intensity required to see fast results. If you are interested in learning more about the device, you can check out where I bought mine on Amazon here and read more details and customer reviews.
I usually use it 10 minutes per day on each area. It’s important to use red light therapy on a clean surface, so use it right after washing your face and before putting on any skincare or makeup. Consistency is key, so I use my machine every day. Within the first month of using the machine, I noticed a regrowth in baby hairs near my hairline that hadn’t existed in over 9 years!
The recommended ways to use RLT machines vary depending on the manufacturer and the specific device. It is important to follow the manufacturer’s instructions carefully and not exceed the recommended exposure time. To use a red light therapy panel, you need to expose your skin to the device for a certain amount of time, depending on the panel and your condition. The recommended duration and frequency of use may vary, but generally, it is suggested to use the panel for 10 to 30 minutes a day, at least 3 times a week, for several weeks or months. Some devices may require protective eyewear to prevent eye damage. It is also important to avoid looking directly at the light source because some may find the light too bright and get eye strain from looking. If you have any concerns about using RLT, consult your healthcare provider.
Potential Side Effects of Red Light Therapy to Be Aware of
Red light therapy is generally considered to be safe and well-tolerated, but there may be some potential side effects or risks in rare cases. The potential side effects of RLT are not well-known, but some people have reported mild side effects such as eye strain, headaches, and sleep disturbances. Here is a more detailed list:
- Eye strain or light sensitivity. Red light therapy devices may emit bright light that can be uncomfortable or harmful to the eyes, especially if used for long periods or without proper eye protection. You should always wear goggles or sunglasses when using red light therapy devices, and avoid looking directly at the light source.
- Headache. Red light therapy may cause headaches in some people, possibly due to the increased blood flow or stimulation of the brain. You should stop the treatment and rest if you experience a headache during or after red light therapy, and consult your doctor if it persists or worsens.
- Skin tightness. Red light therapy may cause a temporary sensation of skin tightness, dryness, or itching, especially in the treated area. This may be due to the increased collagen production or the healing process of the skin. You should moisturize your skin after red light therapy, and avoid using harsh or irritating products on the treated area.
- Skin irritation or burns. Red light therapy may cause skin irritation or burns in some people, especially if they have sensitive skin, allergies, or skin conditions. You should test the device on a small area of your skin before using it on larger or more sensitive areas, and follow the instructions of the device carefully. You should also avoid using red light therapy on open wounds, infections, or inflamed skin, and seek medical attention if you notice any signs of skin damage, such as blisters, redness, swelling, or pain.
These side effects are usually mild and temporary and do not require medical intervention. More research is needed to determine if RLT causes any damage to eyes. Early studies seem to point to no, but more clinical trials need to be done. Other studies have found that stronger, more visible blue and ultraviolet light therapies don’t have a negative impact on eye health or cause any serious side effects. However, you should always consult your doctor before starting red light therapy, especially if you have any medical conditions or are taking any medications that may affect your sensitivity to light. You should also monitor your skin and hair for any changes or adverse reactions, and stop the treatment if you experience any discomfort or worsening of your condition. Red light therapy is not a substitute for professional medical advice, diagnosis, or treatment, and you should always follow the recommendations of your healthcare provider.
