LED Light Therapy: What the Evidence Says

Introduction

LED (Light Emitting Diode) therapy has become popular in skin clinics, but what does the science say?

How It Works

Different light wavelengths interact with the skin in different ways. For example:

•  Red light: often used for skin rejuvenation. Boosts collagen production and helps to reduces redness.

•  Blue light: targets acne-causing bacteria to improve breakouts.

•  Near-Infared: speeds healing, reduces inflammation, and relieves discomfort.

What Research Shows

Clinical studies suggest LED can support skin quality, but results vary between individuals. Multiple sessions are often needed, and effects may be subtle.

Safety

LED is generally considered low risk when delivered correctly. Some people may experience mild redness or sensitivity.

Key Takeaway

LED therapy may be a supportive treatment, but it is not a cure. Evidence is growing, and results differ from person to person.
