Red and Blue Light Therapy
I’ve been getting a lot more questions lately about at home blue light and red light therapy masks, wands, and devices.
Blue light therapy helps target acne-causing bacteria, making it a great option for clearer skin without harsh medications.
Red light therapy works deeper in the skin to reduce inflammation, support healing, and stimulate collagen—helping improve fine lines, redness, and overall skin health.
But here’s where it’s important to understand the difference:
UV light (ultraviolet light) is not the same as these therapies. UV light has shorter, more intense wavelengths that can damage your skin cells, accelerate aging, and increase your risk of skin cancer.
Visible light (like red and blue light) has longer, gentler wavelengths that can be used therapeutically when applied correctly.
With so many at-home devices now available, it’s easy to feel overwhelmed or assume they’re all safe and effective. The reality is: not all devices are created equal, and improper use can lead to irritation, burns, or ineffective results.
That’s why it’s so important to talk with one of our providers before starting light therapy. We’ll help you:
• Choose the right device (if at-home is appropriate)
• Customize a treatment plan for your skin goals
• Avoid unnecessary risks while maximizing results
Your skin deserves a plan that’s both safe and effective!
