While LED therapy is increasing in popularity in the skincare and beauty world, there is such a thing as too much of a good thing. Everything from fluorescent lighting to LEDs, TVs, computers, laptops, smartphones, and tablets submit blue light. With increased time spent directly in front of our mobile devices, it may be negatively impacting your skin and body.
The Beauty Benefits Of Blue LED Light
Let’s first begin with the beauty benefits of blue light. Blue LED light is particularly effective for oily and acne-prone skin. Benefits include:
- Purifying the skin
- Killing bacteria
- Soothing inflammation
- Stabilizing the sebaceous oil glands
- Treating and minimizing pimples and cystic acne
Red and green LEDs also have a variety of beauty benefits.
The Negative Effects Of Too Much Blue Light
On the flipside of the benefits above, overexposure to blue light can damage, shrink, and kill skin cells—all of which can prematurely age your skin. Just as few as 60 minutes a day can trigger cellular damage. In addition, blue light can increase swelling, redness, and pigment changes to those with darker skin.
Reducing exposure to blue light is almost impossible, but just like exposure to harmful sunlight, you can be proactive:
- Wear a broad-spectrum facial sunscreen and body sunscreen of a minimum of SPF 50 every day and reapply to exposed areas every 2 hours. “Broad-spectrum” means it protects from more than just UVA and UVB rays, but from all potentially harmful light sources. Always apply facial sunscreen after your serum and moisturizer.
- Upgrade your daily skincare products to antioxidant-rich formulas that are proven to stimulate cellular repair. We prefer the combination of the AP Repair Cream in the morning, the Tonight Cream in the evening, and the Skinflower Concentrate Anti-Aging Serum both AM and PM.
Don’t Forget Your Eyes
Our eyes are one of the first visible areas of aging, so in addition to your facial products you need to apply an anti-aging eye product both AM and PM. When it comes to blue light exposure you must think beyond the skin around your eyes to your actual eyes.
More research is required, but there is concern that our daily blue light exposure may increase the risk of eye disease. Digital eye strain affects around 50% of computer users, causing dry eyes, irritated eyes, and blurred vision. While not all optometrists agree, wearing blue light filtering glasses may help. Also, turn on the blue light filters or dim the screens on your electronic devices.
Finally, blue light exposure is a stimulant that can slow the natural release of melatonin at night, which can make it more difficult to fall asleep at night or to achieve deep sleep. Sleep is essential for whole-body cellular repair, so it must be a priority. So, keep handheld devices to a minimum 2 hours before bedtime or wear your blue light glasses.
