LED Light Therapy: What It Is & Why I Recommend It

LED light therapy has become a trusted tool in professional skincare, and for good reason. However, not all at-home devices are created equal. At Art of Skin Care, I only recommend LED devices that use clinically proven wavelengths, are FDA approved, and deliver results backed by science.

I've personally selected Omnilux and LightStim for their superior technology and proven performance in reducing wrinkles, clearing acne, and calming inflammation.

Let's take a closer look at how LED therapy works—and why these devices are worth the glow.

LED Light Therapy (short for Light Emitting Diode Therapy) is a non-invasive skincare treatment that uses different wavelengths of light to penetrate the skin and activate natural healing processes. Depending on the color of the light used, it can:

• Boost collagen and elastin production
• Kill acne-causing bacteria
• Calm inflammation and redness
• Brighten and even out skin tone

You might also hear it called photobiomodulation or low-level light therapy. At the end of the day, it’s all about using light to energize your skin from within.

Different wavelengths of light reach different depths of your skin. When these lights reach your skin cells, they wake up your mitochondria (your skin’s little energy factories). That boost in energy tells your cells to start regenerating, repairing, and producing more of the things your skin loves — like collagen, elastin, and antioxidants.

Think of it as fitness for your skin. With consistent use, LED therapy helps your skin become healthier, stronger, and visibly more radiant.

Red Light (Around 633nm): Red light is your go-to for healthy aging and collagen stimulation. It reduces fine lines and wrinkles, calms redness and inflammation, and enhances circulation for a natural glow.

Blue Light (Around 415nm): Blue light is the acne-fighting hero. It destroys acne-causing bacteria, helps reduce oil production, and clears and prevents breakouts.

Near-Infrared Light (830–1072nm): This light goes deeper into the skin to stimulate collagen-producing fibroblasts. It helps firm, plump, and smooth the skin while supporting healing and reducing inflammation.

Combination Light Therapy: The best LED devices combine red, blue, and near-infrared light to target multiple skin concerns at once, like aging and acne.

LED light therapy is safe, non-invasive, and pain-free. It doesn’t use UV light, so there’s no risk of sun damage. However, it’s not for everyone.Avoid LED therapy if:

• You’ve used Accutane in the past 6 months
• You’re prone to seizures or migraines from light
• You have melasma triggered by heat
• You have open wounds or active skin cancer
• You’re on any photosensitizing medications

Always consult your provider if you're unsure.
