Red Light Therapy vs LED Light Therapy
Medically reviewed by Gabi, Aesthetic Clinician · Last reviewed 3 July 2026If you’ve searched for red light therapy and LED light therapy, you’ll notice they’re often used interchangeably. In reality, red light therapy is a type of LED light therapy.
This guide explains the difference in plain English, what wavelengths are typically used, and how to choose the right option for your skin goals.
What is LED light therapy?
LED light therapy is a non-invasive treatment that uses specific wavelengths of light to support skin function. Different colours (wavelengths) are used for different goals, such as breakouts, redness or rejuvenation.
What is red light therapy?
Red light therapy usually refers to visible red wavelengths used for skin rejuvenation and recovery support. It’s commonly chosen for fine lines, dullness and post-treatment redness.
So what’s the difference?
Red light therapy is one part of LED light therapy. LED therapy can also include blue light (often used for acne) and near-infrared light (often used for deeper recovery and comfort).
Which one should you book?
If your main concern is ageing, texture, glow, or recovery, red + near-infrared is usually the best starting point. If your main concern is acne breakouts, blue + red is often used. For mixed concerns, a tri-wave approach can be ideal.
Why a clinic device matters
Clinic-grade LED systems deliver controlled wavelengths, dose and coverage. That consistency is important for repeatable outcomes and for fitting treatments into a safe plan for your skin.
