What is blue light?
Part of the electromagnetic spectrum, blue light is a short wavelength, high energy type of light. While sunlight is a primary source, our exposure has skyrocketed with the advent of artificial lighting and digital screens. While screens emit a fraction of the blue light that the sun does, we do get very up close and personal exposure to our devices, intensifying its effects.
How does blue light affect your skin?
Though its impact isn’t as immediate as a sunburn from UV rays, blue light does take a toll on your skin. Recent research has illuminated the potential consequences of prolonged exposure to blue light. Impacts include:
- Stimulating pigment production. Melanin pigment is responsible for dark spots, aka hyperpigmentation.
- Triggering the generation of reactive oxygen species. ROS are known for causing DNA damage in cells.
- Disrupting the circadian rhythm of skin cells during sleep. Blue light affects our body’s production of melatonin.
- Impacting the crucial nighttime repair process. Blue light impacts skin cells’ ability to transmit and receive crucial signals during regeneration.

Dr. Pimple Popper's tips for protecting skin from blue light
#1 Find ways to minimize exposure
Be mindful of screen time and use tools to cut exposure. Set screen time limits, take regular breaks, and switch to “night mode.” You can also try blue light glasses and special screen covers.
#2 Wear sunscreen even while indoors
Incorporate sunscreen into your daily routine, even when indoors. This precaution helps create a protective barrier against the potential harmful effects of blue light.
#3 Add Antioxidants into your routine
These substances play a vital role in neutralizing free radicals— the damaging chemicals produced by blue light exposure. Look for products containing vitamins C, E, and B-3 (niacinamide), green tea extract, and ferulic acid.
