The science behind LED light therapy

The science behind LED light therapy

In the world of beauty and skincare, it's repeatedly hammered into us to never, ever, go outside without sun protection. Makeup-free days are a relief on the weekend, but we still need a layer of UV-protective lotion to prevent sun damage.

That's because sunlight is one of the many external factors that contribute to premature ageing, manifesting as sunspots and dryness, which leads to wrinkles. It's not at all ideal. However, with advanced technology developing newer and better skin treatments you may have heard of LED light therapy. It's harmless, non-invasive and can provide a wealth of benefits to your skin. How is this light better and what makes it so great? Let's take a look.

The good light for our skin

Sunlight is composed of UV rays. This stands for ultraviolet, and can either be UVA or UVB rays, long waves and short waves respectively. LED stands for light-emitting diode, which are infrared rays, another type of light that's safe for your skin. It was actually NASA that first discovered that LEDs had beneficial properties for collagen production in our skin, when it used them for plant growth stimulation. Now, beauty clinics all around the world have developed this technique as an effective skin treatment.

LED-ing the way

There are three types of infrared light, which all provide your skin different benefits. Red, white and blue infrared lights have different wavelengths and perform different functions, with the white light reaching further through the layers of your skin while blue kills bacteria. These three types of infrared lights all work in conjunction to promote mitochondria activity in your skin cells, which increases collagen production. The end result is clearer skin with less redness and blemishes, as well as a plumper, fuller texture that can last up to six months after treatment.

Your skin will be exposed to LED light for a set amount of time, usually 20 minutes, but no part of the process will any physical item touch your face. It's completely non-invasive, and many people find they prefer it to microdermabrasion or skin needling as it's such a contactless treatment.

LED light therapy provides longer-lasting results, so you may not leave the clinic looking refreshed immediately, but the process of rejuvenation and healing has been stimulated in your skin. You'll see results slowly over the next few months, which ultimately renews your complexion. It can be easily incorporated with other facial treatments for both instant and future results.
