Everything You Need to Know About Light Therapy

You’ve all probably spotted at least one of those scary-looking, light therapy masks whilst scrolling through Instagram but do you actually know what they are or how they work? Light therapy is more than just a social media trend, it actually has the power to give dull, ageing and acne-prone skin a glow boost. Whether you’re going for an in-clinic treatment or trying it at home, here’s everything you need to know…

What is it? 

Light Emitting Diode therapy (or LED) is a non-invasive treatment that uses the non-thermal, narrow band energy from LED light to trigger your body’s natural cell processes which accelerates the repair and rejuvenation of the skin. It can be used to treat a number of skin concerns and conditions such as signs of sun damage, acne, psoriasis, eczema as well as having the ability to heal wounds, scars and restore radiance. 

What does it do? 

When used consistently over a long period of time, the LED lights used during a light therapy session can penetrate your complexion at different depths and cause various reactions within the layers of your skin such as increasing its ability to fight acne-causing bacteria, reduce premature signs of ageing and plump areas of slack, sagging skin. It can also help to brighten the skin and is particularly calming, so after each treatment, you’ll feel super refreshed. 

How does it work? 

This innovative treatment uses a variety of colour wavelengths of visible light which each have their own specific benefit. The skin uses the light as a source of energy to kick-start and boost the repair and rejuvenation process, fixing damaged cells and getting rid of bad bacteria. This energy also boosts the production of collagen and elastin while boosting circulation and tissue repair to improve the skin’s overall health. 

What types of light are there and what do they do? 

Red light: This colour increases the skin’s natural hydration levels, shrinks the appearance of enlarged pores, regulates oil production and reduces signs of inflammation. It can also accelerate the skin’s natural repair process and is ideal for treating rosacea. 

White or infra-red light: This is the wavelength that the skin can absorb the deepest. It increases cell absorption and permeability, improves elasticity, smoothes wrinkles and fines lines, and reduces signs of inflammation. It can also be used to accelerate wound healing and treat cystic acne.  

Blue light: This type has powerful antibacterial properties and is perfect for treating acne without causing irritation. It can effectively reduce sebum production, prevent future breakouts and can also offer a UV-free alternative for the treatment of psoriasis and eczema. 

Go to a clinic or use an at-home treatment? 

At-home devices don’t boast the same power as the professional machines used in clinics. However, if you use an effective LED mask or device consecutively, for a long period of time, it will provide you with similar results as one clinic treatment, if you went once a week for the same period. The results from this treatment are instant and long-term because light therapy works on a cellular level, so you will leave each session more glowing than the last.
