Light comes in different wavelengths that are described as colors. LED lights can harness certain light colors like blue or red light. Blue LED aesthetic treatment can have benefits for the skin and may be an option for improving its health and appearance.
What Is LED Light Therapy?
The light spectrum varies from red light with the longest wavelengths to violet with the shortest wavelengths. Each impacts the skin differently – blue light is close to the violet end of the spectrum. When using blue LED lights, aesthetic skin treatment can be performed.
LED stands for light-emitting diode, a type of light that NASA first developed for growing plants in space. The light bulbs can be tailored for different wavelengths to affect the skin, and the treatment is used by many dermatologists for various skin conditions.
While red light can go deeper into the skin, the longer wavelengths and shorter frequency of blue light impact the skin’s surface. LED light therapy can be used for a variety of skin conditions, from skin cancer and acne to rosacea, eczema and aging issues, using different colors for different conditions.
Blue LED Aesthetic Therapy
With blue LED lights, aesthetic treatment can be performed to improve the health and appearance of the skin. Since blue light does not penetrate as deep as red light, the main effects are on the surface. The long wavelengths can impact bacteria on the skin and may have other benefits. Here are some uses.
- Acne Treatment
- One of the most common uses of blue LED aesthetic treatment is for controlling acne. Blue light can kill certain bacteria that can lead to acne breakouts. Propionibacterium acnes are sensitive to blue light. Using blue LED light aesthetic treatments can benefit those with this type of acne.
- Blue light therapy can also help with other types of acne by reducing activity in the sebaceous glands in the skin. Sebaceous glands release oils that can contribute to acne breakouts. By reducing the output of oils, acne can be lessened for better skin health and appearance.
- Skin Cancer Treatment
- What is LED light therapy for skin cancer? Certain non-melanoma skin cancers and precancerous conditions can be treated with blue LED light therapy. This type of treatment is called photodynamic therapy or phototherapy, which can remove surface skin cancer cells to prevent them from spreading.
- Sun damage to the skin can cause actinic keratoses, small scaley patches on the skin. These reddish growths can be precancerous and lead to squamous cell carcinoma or SCC. Blue light therapy can be used to remove the sun-damaged skin and actinic keratoses to prevent cancer and improve skin appearance.
- Wound Healing
- When using blue LED lights, aesthetic treatment is not the only benefit. Blue light has been used for wound healing and preventing infection. Like controlling acne, blue light can kill bacteria that can impact wound healing and cause infection.
- Rosacea Treatment
- Blue and red LED light therapy can be beneficial for rosacea treatment. Blue LED light therapy can reduce surface bacteria and oil secretions, which can help minimize rosacea sensitivity. Red light therapy can be even more beneficial, reducing redness and inflammation while promoting collagen production.
Is Blue LED Aesthetic Treatment Right for You?
For those with sun damage, acne, rosacea and skin cancer risks, blue LED light therapy can have many benefits. The treatments are non-invasive and require no downtime after each therapy session. While you can find home blue light devices, it is best to see a dermatologist for blue light therapy.
Most blue LED light treatments last between 15 and 90 minutes, depending on the condition treated. However, some treatments may require medication added to the skin before the blue light treatment begins. The therapy is not painful, and you can return to normal activities after your session.
Blue LED light treatments are usually performed in a series. Acne treatments may require up to six treatments, while actinic keratoses may only need one to four sessions. There may be some flaking and peeling of the treated skin in the days and weeks after blue light therapy, but this is normal.
Blue light treatments can effectively control certain skin conditions, but you want to ensure that they are performed safely. Side effects can include skin sensitivity, including light sensitivity, especially for those who had light-sensitive medications applied before their blue light therapy. Your doctor should perform all light treatments.
Contact a dermatologist to learn more about the benefits of blue LED aesthetic treatment for acne, skin cancer, rosacea, and other conditions. Your skin specialist can discuss whether this form of blue LED light treatment can be beneficial for improving your skin health and aesthetic appearance.
