Does Blue Light Age Your Skin?

With an increase of time spent on digital devices, a focus has turned to blue light and if excessive daily amounts of this light wavelength can contribute to damage within our eyes, skin, and overall health.


It is early stages, but studies have discovered that blue light like UV, can penetrate the skin and may contribute to ageing, breakdown of collagen, production of pigmentation/melasma and free radicals.


This form of light is the short-wavelength blue/violet band of the visible light spectrum. It is an important wavelength that also radiates from the sun and regulates our body’s circadian rhythm. It is also proven to effectively treat acne when exposure is controlled with machinery like LED Light Therapy. Blue light makes up about 35% of the sun’s electromagnetic radiation but also found in smartphones, computers, televisions, fluorescent and LED lighting


A recent study has shown we spend on average approximately 10 hours a day exposed to digital devices. It is something we cannot escape so we must incorporate ways to balance the combination of UV and blue light. Ensure your morning skincare regime includes a good quality SPF that contains zinc oxidise. This ingredient acts like a barrier helping to reflect UV rays and blue light. This is important even if you don’t head out of the house for the day. Wearing a SPF daily should now be thought of as your ‘Day Time Protection’, not sun protection. In the evening include antioxidant-filled night time products to help tackle free radical exposure and repair your skin.


 What else can be done? Limit your exposure to devices over the whole day, see if your phone has the abilty to limit blue light, turn off devices 30 minutes before bed,  and sit further away from the television or computer if possible.

NEW! Dermalogica Invisible Physical Defense SPF30





NEW! Invisible Physical Defense spf30

Want to know the most important step of your skin care regime?  Well, it’s  sunscreen.  Not only is it your number 1 age management step but a skin cancer prevention mitigator! It is essential to wear on those bright sunny days and we have been educated to wear even on those cloudy days where we are unknowingly exposed to harmful, skin ageing rays. Recently it has been discovered that Blue light from our devices can penetrate our skin and cause our skin to develop uneven pigment and also accelerate the ageing process.


Here is a quick 101 on the sun and its damaging rays:

UVA (think A for ageing) – This ray can travel through your windows in your home, car or office and travels deep into the skin where collagen and elastic are found and in turn damaged.

UVB (think B for burning) – This ray is out in full force from 10-3pm though it varies depending on the time of year.  This high energy ray burns our skin and causes our skin to tan.  Never be under the impression a tan is healthy as it is a hallmark of damage that has been inflicted on your skin.

Blue Light – Found in the visible light spectrum of the sun and also emitted from devices.  This is a long reaching ray which travels deeply into the skin damaging the skin cells along with collagen and elastin.

So, with all this awareness, why do we still try and dodge this skin critical step? Well, it mostly comes down to not liking the solution.  

We’ve all experienced, thick, gluggy sunscreens that leave a chalky white wash of colour on the skin. If only we had a sunscreen that was invisible and ANY skin tone or type could use. Well, now we do. Introducing Dermalogica’s NEW Invisible Physical Defense SPF30 

Invisible Physical Defense SPF30 is a physical sunscreen like no other. Physical sunscreens use minerals, such as Zinc Oxide, that sit on the skin and reflect away UV rays. Unfortunately, the minerals don’t blend easily, which is why we’re left with the white residue.  

Dermalogica’s NEW Invisible Physical Defense SPF30 uses a unique ultra-sheer Zinc Oxide. Ultra-fine particles of Zinc Oxide, carried by plant-based oils, make for a physical sunscreen that’s invisible and blends to all skin tones. This means that EVERYONE can use it. Being a physical sunscreen and with adding soothing ingredients, it’s also a good option for sensitive skins. 

What’s more, Invisible Physical Defense SPF30 provides protection against blue light, a form of radiation emitted from our everyday smart devices. Whilst research is ongoing, we know this poses a new threat to the health and age of our skin. 

Along with the advanced ultra-sheer Zinc Oxide, Invisible Physical Defense SPF30 contains: 

·         Hyaluronic Acid – Known to dramatically increase moisture, plumpness and minimise fine lines. 

·         Bioactive Mushroom Complex – Derived from the Himalayas, this mushroom duo serves to soothe, treat UV related redness and dryness. 

·          Matcha Green Tea – A super potent antioxidant that protects against the harmful effects of UV and blue light. 

·         Argan Oil, Vitamin E and Chamomile – Work together to protect, soothe and nourish the skin. 

Invisible Physical Defense SPF30 is your last step in your skincare regimen in the morning. A teaspoon amount is recommended for the face, neck and ears. Layer over one of Dermalogica’s Daily Skin Health moisturisers. Choose Active Moist for an oiler skin; Skin Smoothing Cream for a combination/dehydrated skin, and Intensive Moisture Balance for a drier and/or mature skin.
