As practitioners many of use microneedling, red light therapy and or microneedling devices in our practice. The skin care industry is seeing a rise in multifunctional devices that combine microneedling, microcurrent, and red light therapy. While convenient, these all-in-one tools raise questions about their safety and effectiveness when used together. In my book Treating the Face: A Comprehensive Guide for Acupuncturists and Health Professionals, I emphasize the importance of understanding the distinct requirements of each therapy to maximize benefits and ensure patient safety.
Microneedling and Microcurrent: A Risky Combination
Microneedling works by creating micro-injuries to stimulate collagen production, but when combined with microcurrent therapy—which uses low-level electrical currents to tone facial muscles—risks can increase. Microcurrent on freshly needled skin can potentially irritate, or even damage, sensitive tissue. Therefore, combining these treatments without professional oversight may lead to unintended side effects, including infection or skin irritation.
Red Light Therapy: The Need for Adequate Exposure
Red light therapy (RLT) is widely recognized for its ability to boost collagen production and reduce inflammation. However, for RLT to be effective, research suggests a minimum application time of 30 minutes per area at an appropriate power. Shorter durations might fail to penetrate deeply enough, missing the collagen-stimulating benefits that users expect.
Microneedling Speed: The Role of RPMs
The speed of microneedling devices, measured in revolutions per minute (RPM), is crucial for effective treatment. Professional grade microneedling devices typically operate at 18,000 RPM or higher. Slower speeds may not stimulate the skin adequately, leading to less visible results. From a safety perspective, they may drag on the skin, and irritate or tear delicate facial skin. Many multifunctional devices operate below this speed, potentially compromising microneedling effectiveness.
Multifunctional Devices: A Compromise on Quality?
While multifunctional devices are marketed for convenience, they may fall short in several areas:
- Red Light Therapy: Reduced exposure time limits effectiveness.
- Microneedling and Microcurrent: Simultaneous application can increase safety risks, especially with microcurrent on needled skin.
- Microneedling Speed: Lower RPMs may result in insufficient skin stimulation.
For those serious about providing the best service for their patients, investing in devices designed for a specific purpose may yield safer and more effective results.
