Red light therapy is safe when used correctly. It uses visible light (630-700nm) and near-infrared light (700-1100nm) and does not contain ultraviolet light, so it does not increase the risk of skin cancer or sunburn like ultraviolet light. Clinical studies support its use in acne, hair loss, anti-inflammatory and skin repair, and as a non-invasive treatment, it is generally well tolerated.
But be careful: avoid looking directly at the light source for a long time to prevent eye damage, sensitive skin may experience temporary redness or dryness, and low-quality equipment may cause burns. People with photosensitive diseases, pregnant women or those using photosensitive drugs should be cautious or avoid use.
To ensure safety, it is recommended to choose FDA-certified equipment, control the dosage (10-20 minutes each time, 2-3 times a week), and do a skin test before first use. Avoid using it with photosensitive skin care products (such as tretinoin), and home devices must strictly follow the instructions. If you have special health conditions, it is recommended to consult a doctor before red light therapy.
What Is Red Light Therapy?
A red light therapy machine is a treatment method that uses red visible light of a specific wavelength. It acts on human tissues by emitting red light of 600-700 nanometers, bringing a series of health benefits. The principle of this therapy is based on photobiological regulation. Simply put, when human cells receive red light of a specific wavelength, it will trigger a series of biochemical reactions in the cells, thereby promoting cell metabolism, repair, and regeneration.

How does red light therapy work?
When we use red light devices, such as red light therapy module or red light panel, the red light emitted by these devices can penetrate the surface of the skin and reach the subcutaneous tissue. The mitochondria in the cells are like energy factories. They contain pigments that are sensitive to red light and can absorb red light energy. After absorbing energy, the mitochondria will accelerate the production of adenosine triphosphate (ATP) in the cells, provide more energy for the cells, and then promote various physiological activities of the cells, such as repairing damaged tissues and enhancing the activity of immune cells.

Common uses of red light therapy
Red light therapy machine has applications in many aspects. In the field of skincare, it can promote the production of collagen, help reduce wrinkles, improve skin sagging, and make the skin more elastic. For muscle and joint problems, red light therapy devices can promote local blood circulation, relieve pain and inflammation, and help muscles recover faster. In addition, it can improve sleep quality and make it easier for people to enter a deep sleep state by regulating the body's biological clock and hormone levels.

Potential side effects and risks
In general, red light therapy devices are relatively safe, but there may be some potential risks. For example, long-term or excessive use of red light devices may cause slight redness, heating, or even burns on the skin. In addition, if the quality of the device used is not up to standard and the wavelength of light emitted is not accurate, it may not achieve the desired treatment effect and may even cause adverse effects on the body.
Who should avoid red light therapy?
Although red light therapy devices have many benefits, it is not suitable for everyone. For people with photosensitive diseases, such as hereditary porphyria, exposure to red light may cause allergies or other adverse reactions. In addition, people with open wounds or severe skin diseases are not recommended to use red light therapy to avoid irritating the wounds and aggravating the condition. In addition, people who are undergoing certain special treatments, such as taking photosensitive drugs, need to consult a doctor before using red light therapy.
How to Use Red Light Therapy Safely
Recommended duration and frequency of treatment
When using red light therapy, it is necessary to control the duration and frequency of the treatment. Generally speaking, it is appropriate to use the red light therapy module or red light panel for about 10-20 minutes each time, 3-4 times a week. However, the specific duration and frequency need to be adjusted according to the individual's physical condition and treatment purpose. If it is used for daily skin care, the frequency can be appropriately reduced; if it is used to treat muscle and joint pain, the number of uses can be appropriately increased under the guidance of a doctor, but it should not be excessive.
Choose the right home device.
When choosing a home red light therapy device, pay attention to the quality and performance of the device. Red light products like PRUNGO use advanced technology and high-quality materials. PRUNGO's red light therapy module and red light panel can not only accurately emit red light wavelengths that meet treatment standards but also pay attention to the safety design of the equipment, such as setting up an intelligent timing function to avoid damage caused by long-term use. At the same time, the illumination range of PRUNGO products is uniform, allowing all parts of the body to be effectively treated.
Eye and skin protection measures
When using medical-grade red light therapy devices, be sure to protect your eyes and skin. The eyes are sensitive to light, and direct exposure to red light may damage the retina, so special goggles should be worn when using them. For the skin, although red light therapy is relatively mild, protection should not be ignored. You can apply an appropriate amount of skin cream to the treatment area to reduce the irritation of light to the skin. In addition, do not use red light equipment directly on damaged or inflamed skin.

Comparison of Red Light Therapy with Other Therapies
Red light therapy and ultraviolet therapy
Both red light therapy and ultraviolet therapy are phototherapy, but they are very different. Ultraviolet therapy is mainly used to treat skin diseases, such as psoriasis, but ultraviolet rays can cause certain damage to the skin. Excessive exposure may cause skin aging and increase the risk of skin cancer. Red light therapy is relatively mild. It will not cause obvious damage to the skin. It promotes cell repair and regeneration and plays a dual role in maintenance and treatment.
Red light therapy and laser therapy
The energy of laser therapy is relatively concentrated, and the treatment effect is significant, but it usually requires professional operation, and there may be pain during the treatment, and the cost is relatively high. In contrast, red light therapy is more convenient to use. Household equipment such as PRUNGO's Red light panel can be operated by ordinary people at home. The energy distribution of red light therapy is more uniform, and the treatment process is comfortable. It is suitable for daily health care and the treatment of some mild diseases.
