LED Light Therapy: How Different Colors Affect Skin Concerns
In the ever-evolving world of aesthetics, few treatments have stood the test of time and innovation quite like LED light therapy. Once used by NASA to help astronauts heal wounds in space, LED therapy has become a skincare staple—safe, non-invasive, and remarkably effective. Whether you're targeting breakouts, aging, inflammation, or dullness, light wavelengths hold the power to transform skin at the cellular level.
At Glownar Aesthetics, we offer advanced LED panels designed for professional use that help you give your clients visible results in just a few sessions. In this blog, we’ll break down what each light color does, and highlight some of our favorite LED devices that are trusted by top estheticians and med spas.
What Is LED Light Therapy?
LED (Light Emitting Diode) therapy uses specific wavelengths of light to penetrate the skin and trigger natural healing responses in the body. Unlike UV rays, which damage skin, LED lights are completely safe and promote healthier, more balanced skin.
Different light colors reach different layers of the skin and target specific concerns. That’s why many professional LED panels come with multiple light settings—so you can customize treatments based on what your client needs most.
Red Light (630–700 nm): The Anti-Aging Powerhouse
Red LED light is one of the most popular wavelengths used in facial treatments—and for good reason. Penetrating the skin at a mid-to-deep level, red light stimulates fibroblast activity, encouraging the production of collagen and elastin, the proteins responsible for maintaining firm, youthful skin.
Key Benefits of Red LED:
-
Reduces fine lines and wrinkles
-
Improves skin texture and tone
-
Increases circulation and cellular turnover
-
Speeds up wound healing
-
Reduces inflammation and redness
Red light therapy is particularly effective for mature clients or those looking to maintain a healthy, youthful glow. It can be used post-procedure to support recovery or as a standalone anti-aging treatment. Red light is especially beneficial as a calming finish after treatments like microneedling or chemical peels,
Blue Light (405–470 nm): The Breakout Fighter
If red light is the hero of anti-aging, then blue light is the champion of clear skin. Blue LED light works closer to the skin’s surface and has powerful antibacterial properties. It specifically targets Propionibacterium acnes (P. acnes), the acne-causing bacteria that thrives in clogged pores and causes inflammation.
- Key Benefits of Blue LED:
-
Kills acne-causing bacteria
-
Can help control active breakouts
-
Soothes inflammation and redness
-
Balances sebum production
Unlike topical acne treatments that may dry or irritate the skin, blue light therapy is gentle, non-invasive, and safe for regular use. It's suitable for clients with mild to moderate acne and those with sensitive or reactive skin types.
Other LED Colors and Their Skin Benefits
While red and blue light steal the spotlight, several other colors play supporting roles in full-spectrum LED therapy devices:
Green Light (520–560 nm)
Great for pigmentation concerns, green light helps:
-
Fade hyperpigmentation and sun spots
-
Even out skin tone
-
Calm the skin and reduce redness
Yellow Light (570–590 nm)
This soothing wavelength:
-
Improves lymphatic flow
-
Reduces redness and irritation
-
Boosts skin radiance
Purple Light (Combination of Red + Blue)
-
Combines anti-acne and anti-aging benefits
-
Stimulates collagen while targeting bacteria
White Light (Broad Spectrum)
-
Penetrates the deepest layers of the skin
-
Helps tighten skin and reduce inflammation
Professional-grade LED panels often include multiple color settings or combinations, allowing aestheticians to create custom protocols tailored to each client’s needs.
