The Rise of Blue Light SPF: Digital Age Sunscreens

Today's digital-dominated era has sparked a skincare concern: blue light's effects. Emitted from devices like smartphones and computers, blue light exposure can accelerate skin aging. Recognizing this, the beauty industry has introduced blue light SPFs, specially designed to counteract these effects.

Blue light, or High Energy Visible (HEV) light, is close in wavelength to UV rays. It can lead to collagen degradation, skin dullness, and hyperpigmentation. While traditional sunscreens protect against UVA and UVB rays, they miss HEV light.

Modern blue light SPFs bridge this gap. They use ingredients like iron oxide to block or absorb blue light. Plus, many incorporate antioxidants to combat blue light-induced free radicals.

With this evolution, blue light protection is now found not just in sunscreens but also daily moisturizers and foundations. It's an industry response to our tech-heavy lifestyles, ensuring our skin stays safeguarded in the digital age.
