LED vs Infrared Lights: What Dermatologists Want You to Know

If you’ve delved into the world of light therapy for skincare, you've likely encountered terms like LED and infrared. But do you know the difference? Here's what dermatologists want you to know about these powerful – yet distinctly different – technologies.
Understanding the Difference
LED (Light Emitting Diode) therapy is a wide-ranging term that encompasses various wavelengths of light, each serving different purposes. The visible spectrum includes blue light (targeting bacteria and breakouts), red light (promoting collagen and skin healing), and yellow light (reducing inflammation and brightening). Infrared light, while technically part of the LED family, operates beyond the visible spectrum at longer wavelengths.
The key difference lies in penetration depth. Visible LED wavelengths work on the skin's surface and upper layers, while infrared light penetrates deeper into the dermis, reaching tissues where cellular regeneration occurs most effectively.
Why Dermatologists Recommend a Combination of LED and Infrared Lights
A dermatologist recommended LED mask typically combines multiple wavelengths to address various skin concerns simultaneously. This approach mirrors professional treatments offered in clinics, where practitioners layer different light therapies for optimal results.
Our Sonna Brightening LED Face Mask exemplifies this professional approach, featuring four wavelengths of light: near-infrared (850nm), red (660nm), blue (415nm) and yellow (590nm). With 488 lights working at a cellular level, it delivers the comprehensive treatment dermatologists recommend.
Dermatologists emphasise that while visible LED lights excel at targeting specific surface concerns like redness or uneven tone, infrared light works beneath the surface to stimulate collagen production and improve overall skin structure. Together, they create a comprehensive treatment that addresses both immediate and long-term skin health.
The Infrared Advantage
Infrared light's deeper penetration makes it particularly effective for concerns that originate below the skin's surface. This includes fine lines, loss of firmness and sluggish cellular turnover. By energising cells at their source, infrared therapy supports your skin's natural ability to repair and regenerate.
