If you’ve been exploring at-home skincare devices, you’ve likely come across LED light therapy. From face masks to handheld tools, LED devices promise smoother, clearer-looking skin—without needles, downtime, or complicated routines.
But how does LED light therapy actually work, which colors do what, and how can you use it safely at home? This complete guide from Beautenova explains everything you need to know so you can build a realistic, effective routine with confidence.
Quick takeaway: LED light therapy works best as a consistency-based skincare tool. Gentle, regular use over time often leads to more noticeable improvements than occasional intensive sessions.

What Is LED Light Therapy?
LED stands for light-emitting diode. In skincare, LED light therapy uses specific wavelengths of light to interact with the skin’s surface. This non-invasive approach is often discussed under the broader concept of photobiomodulation.
At-home LED devices are designed for cosmetic skincare routines—not medical treatments. Rather than delivering heat or damaging the skin, they provide controlled light exposure that supports a more balanced, refreshed-looking complexion over time.
How LED Light Therapy Works
Different wavelengths of light penetrate the skin at different depths. When absorbed, this light may support natural skin processes associated with texture, tone, and overall appearance.
In practice, an effective LED device focuses on three essentials:
- Stable wavelength output
- Even light distribution
- User comfort, which determines consistency

LED Colors Explained: What Each Light Is Commonly Used For
Red Light
Red light therapy is commonly associated with supporting smoother-looking skin and improving the appearance of fine lines. Many people use red light as part of a long-term glow and texture-support routine.
Near-Infrared (NIR)
Near-infrared light is often paired with red light to create a deeper-feeling, more comprehensive skincare experience focused on comfort and overall skin vitality.
Blue Light
Blue light therapy is frequently used in routines for blemish-prone skin. It is often combined with gentle cleansing and barrier-supporting skincare products.
Green Light
Green light is commonly discussed in tone-focused routines and is often chosen by users aiming for a more even-looking complexion.
Amber / Yellow Light
Amber or yellow light is typically positioned as calming and soothing, making it popular for sensitive or reactive-feeling skin.
Note: LED color benefits may vary by device and individual. Focus on comfort, consistency, and realistic expectations.
