How does light therapy work?

LED red light therapy uses a process called photodynamic therapy (PDT). But first a quick look at what light is - Light is part of the electromagnetic spectrum, a form of energy that comes in various wavelengths. These wavelengths are basically the colours that we see and each of these different wavelengths cause a very different cellular reaction in the skin.

Back to LED red light therapy, this treatment involves using a light-emitting device to destroy acne-causing bacteria. The light energy from the device is absorbed by the bacteria, causing them to produce oxygen radicals that destroy the bacteria. bacteria can’t survive in an aerobic environment.

What are the benefits of red light therapy for acne?

From all the wavelengths of LED light therapy for acne, blue LED light is considered the most effective. Blue LED Light works in a number of ways to control acne/breakouts:

Antibacterial Properties – as discussed previously blue light sets off a chemical reaction that eliminates acne-causing bacteria, P. acnes. This bacterium produces a protein called porphyrins, which then absorbs the blue light, and a chemical reaction begins, killing the bacteria

Regulates Sebum Production - excess sebum can clog pores and is a key component in the acne cycle, reducing this will help to prevent break the acne cycle

Improves Inflammation – works to reduce redness associated with acne and breakouts, however if you have more redness and inflammation, we suggest using red LED light therapy.

Red LED light has anti-inflammatory benefits, which is why it can be used in conjunction with blue light for acne, especially moderate to severe

Red light also helps to increase the skin's wound healing processes, which boosts, the regeneration of collagen and elastin, which can be very helpful in addressing acne scarring

Once you get scarring especially pitted scarring, LED light therapy may not be the best treatment and we would recommend professional microneedling, chemical peels etc.


Are there any side effects?

LED light therapy for acne treatments offer a great alternative to the standard topical and oral acne treatments out there. It’s no chemicals, no pills approach, however some severities of acne may need a prescription treatment to bring it control before using LED light therapy


How often should you have light therapy for acne?

There needs to be adequate time spent under the light for continuous periods of several weeks. With acne if its hormonal you may only be able to control it and not treat it for good. Therefore, a careful maintenance program needs to be followed.

Each of our devices have a separate protocol for usage so follow the instructions carefully. On average we recommend 10-20 minutes usage 4 times a week minimum.
