Red light therapy generally does not cause skin cancer when used correctly. Red light is non-ionizing radiation with low energy and does not damage DNA. Current studies have not found evidence that it is directly carcinogenic.
Instead, it may play a therapeutic role by stimulating cell metabolism and reducing inflammation, and may even have a certain protective effect. However, it is necessary to pay attention to standardized operation and avoid long-term high-intensity exposure or use of inferior equipment (which may be doped with harmful wavelengths).
Existing clinical data believe that red light therapy devices are safe, which is completely different from carcinogenic light such as ultraviolet rays. However, the long-term effects of overexposure still need more research, and patients with sensitive skin or photosensitive diseases should be cautious. It is recommended to choose regular equipment and follow treatment parameters to minimize potential risks.
What Is Red Light Therapy?
Red light therapy is a form of photomedicine. It mainly uses low-intensity red light to irradiate the skin for a specific period. This therapy is not new. The red light it uses is part of the visible spectrum, which is different from the light we are exposed to in daily life. It has specific requirements in terms of purity, optical density, and machine power. The wavelength is generally between 630nm and 700nm.
In daily life, we see red light therapy being used in a variety of devices, such as portable wands, lamps, masks, etc. Today, it is not only popular in the offices of professional beauticians, but also in the home.
How Does Red Light Therapy Work?
The key to red light therapy is the mitochondria of the cell. When red light of a specific wavelength penetrates the skin, it is absorbed by the mitochondria. Mitochondria are the powerhouse of the cell and play an essential role in human energy production. When red light is absorbed, it can enhance the flow of electrons, oxygen uptake, and ATP (adenosine triphosphate) levels in the mitochondria.
In simple terms, it is like injecting more power into the cell's energy factory, which boosts the cell's energy center. At this point, the cell can better perform the functions it was originally designed to do, such as repair and growth. The red light emitted by our PRUNGO brand red light therapy module acts precisely on the cell's mitochondria to make the cell energetic.
Common Uses of Red Light Therapy
Red light therapy machine is widely used in the medical field. In terms of skin disease treatment, it can be used to treat a variety of skin problems such as herpes zoster, erysipelas, phlebitis, dermatitis, acne, alopecia areata, rosacea, frostbite, folliculitis, eczema, lower limb ulcers, bedsores, paronychia, anal itching, etc. By promoting skin metabolism, it can accelerate wound healing and has anti-inflammatory and analgesic effects, thereby improving skin condition.
In surgical diseases, wound infection, abscesses, ulcers, burns, lumbar muscle strain, periarthritis of the shoulder, soft tissue contusion, etc., red light therapy machine also has a good therapeutic effect. It can promote protein synthesis, accelerate tissue repair, and reduce inflammation and pain.
Understand the Connection Between Red Light Therapy and Skin Cancer
Current studies have shown that exposure to red light generally does not cause skin cancer under normal circumstances. Skin cancer, as a common malignant tumor, mainly includes squamous cell carcinoma, basal cell carcinoma, malignant melanoma, etc.
Its occurrence is closely related to long-term exposure to ultraviolet radiation, chemical carcinogens, ionizing radiation, chronic infection, and other factors. Red light is non-ionizing radiation and is relatively less harmful to the human body.
In principle, it is fundamentally different from the factors that cause skin cancer. However, some people are still worried about whether long-term exposure to high-intensity red light will increase the risk of skin cancer. There is no conclusive evidence to show this association, but excessive exposure may affect other aspects of the body, which is also something we need to pay attention to.
When developing red light therapy modules and red light panels, our PRUNGO brand fully considered safety and strictly controlled the intensity and range of red light exposure to avoid potential risks.

Potential Risks and Safety Hazards of Red Light Therapy
Will red light therapy damage skin cells?
Within normal use specifications, red light therapy devices will not damage skin cells, but on the contrary, they can promote cell repair and growth. However, if used improperly, such as long-term use of red light that exceeds the specified dose of the device, it may have adverse effects on skin cells.
Because cells have a certain limit to their absorption and tolerance of red light, excessive exposure may break the normal physiological balance of cells and cause cell dysfunction. The red light therapy module of the PRUNGO brand is fully considered in its design, and the red light output is precisely regulated to ensure cell safety.
Overuse and skin sensitivity
Overuse of red light therapy may cause skin sensitivity. When the skin is exposed to red light for a long time and at a high frequency, the skin's self-regulation mechanism may be disturbed. Originally healthy skin may show sensitive symptoms such as redness, dryness, and itching. Just as our body will experience various discomforts if it is overworked, the skin will also have adverse reactions to excessive red light stimulation.
FDA regulations on red light therapy devices
The U.S. Food and Drug Administration (FDA) has relevant regulations for red light therapy devices. These regulations are designed to ensure the safety and effectiveness of the equipment. Red light therapy devices approved by the FDA have been strictly tested in terms of performance, safety, etc.
For example, the red light wavelength, intensity, exposure time, and other parameters of the device have clear standards, and only devices that meet these standards are allowed to enter the market. Our PRUNGO brand is committed to complying with FDA regulations.
Our red light therapy module and red light panel strictly follow relevant standards during the research development and production process to provide users with safe and reliable products.

How to Use Red Light Therapy Safely
Recommended exposure time and frequency
How Often Red Light Therapy?Generally speaking, in order to achieve the best results and ensure safety, red light therapy is usually performed 3-5 times a week. Each treatment usually lasts 10-15 minutes, and the specific time and frequency need to be adjusted according to the device used and the individual's specific treatment goals.
For example, if the purpose is to improve fine lines on the skin, it may be sufficient to follow the recommended frequency and time; but if it is to treat more severe skin wounds, it may be necessary to make appropriate adjustments under the guidance of a doctor.
