You know how important it is to protect your eyes from the artificial blue light emitted by cellphones, computer screens and TVs…
But did you know blue light can also damage your skin? Even when taking a selfie.
Blue light penetrates even deeper into your skin than UVA and UVB light… passing through the epidermis and dermis all the way to the subcutaneous layer. This innermost layer is made up of fat, collagen and elastin. Damage to this level can actually change the shape of your face.
One study found that 30 hours of blue light exposure can increase inflammation in your skin cells by 40%.1 A second study found that DNA-damaging free radical production starts after only three hours of exposure.2
The average American spends almost 11 hours a day staring at one screen or another.
This exposure can lead to:
|
• Hyperpigmentation and age spots |
• Inflammation |
|
• Accelerated photoaging |
• Sagging skin |
|
• Collagen breakdown and wrinkles |
• Skin Cancer |
In a moment, I’ll tell you the top five ways you can protect your skin from further blue light emission. But first I want to help you repair the damage that’s already been done…
The most effective way to heal the damage caused by blue light – and bring back ageless skin – is with a powerful enzyme called superoxide dismutase, or SOD.
SOD is your body’s master antioxidant.
It works by neutralizing the MOST dangerous free radicals in your body. I’m talking about superoxide radicals or “anions.” Overexposure to UV rays from the sun creates these nasty anions. And so does blue light. In fact, blue light starts to create anions in seconds.3
Each of your cells suffers about 10,000 “hits” a day from these free radicals. Superoxide free radicals burn holes in cell membranes. They destroy enzymes, proteins, fats and DNA molecules. They alter the way cells code genetic material. They cause inflammation.
Most antioxidants can’t touch these superoxide radicals. Only SOD is strong enough to take them on. In fact, it has 3,500 times the antioxidant power of vitamin C.
SOD triggers the conversion of superoxide radicals into hydrogen peroxide, a less harmful oxygen-based free radical.4 In other words, they become harmless oxygen and water. SOD then remains on site to extinguish the fiery inflammation that follows.
The best source of topical SOD comes from an unusual source – snail serum. You see, snail goo is similar to human skin. And it contains a complex mixture of chemicals that help the snail regenerate after injury. In fact, clinical research supports just how effective snail serum is at building healthy human skin.
One study published in the journal Skin Pharmacology and Physiology shows that along with its antioxidant protection, snail slime improves signs of photo-aging and promotes skin cell creation and survival.
And in two recent studies, researchers looked at the effects of snail serum on skin cells exposed to severe air pollution. They found that treating tissue with snail serum protected the skin by as much as 30%5 and prevented apoptosis — or the death of existing skin cells.6
The cosmetic name for this slimy excretion is snail filtrate. It’s widely used in Korea, but it’s becoming more popular in the rest of the world.
Cut back on selfies and other tips for blue light protection
To protect your skin from blue light I suggest you start doing the following:
- Turn on your screen’s blue light filter. On the iPhone, you can find it in Settings > Display & Brightness. For an Android, it’s in Settings > Display.
- Hold your mobile device at a 30-degree angle. Blue light travels from your screen in straight lines. You’ll reduce the blue light that hits your face but still be able to read it.
- Use a screen filter. Blue light filters for mobile devices cost around $35. For monitors and TVs, you have more options — prices for a 22″ monitor start at around $50.
To Your Good Health,
