Blue light is a visible spectrum originating from sunlight and artificial sources, such as computer, television, and smartphone screens. Since technology is increasingly part of our daily lives, avoiding exposure to these rays is hard.
What you may not know is that blue light can also harm our health and skin, and that, similar to wearing sunscreen to protect from UV rays, we should protect ourselves from blue light.
BLUE LIGHT AND THE SKIN
Do you remember free radicals, responsible for the oxidation of our skin? Blue light stimulates their production! It can reach the dermis, where collagen and elastin are located, and degrades cells, speeding up premature aging. Additionally, because of its oxidant activity, unprotected exposure to blue light causes hyperpigmentation and melasma.
BLUE LIGHT VS. UV LIGHT

While blue light oxidizes skin cells, accelerating premature cellular aging and causing blemishes, UV rays directly affect cellular DNA, being much more potent than blue light radiation and even leading to skin cancer.
Both deserve attention; however, there is no need to panic. A good skincare routine with antioxidant products and daily use of sunscreen is already enough to protect your skin.
HOW TO PROTECT YOUR SKIN AGAINST BLUE LIGHT
It’s not because of its color! Our Niacinamide Serum has potent antioxidant activity that provides a stabilizing effect on the skin’s natural protection barrier. Its protective function works against urban pollution and the blue light from electronic devices.

BEYOND THE SKIN
Blue light also interferes with sleep quality. Ideally, you should turn off lights and electronic devices at least one hour before going to sleep. Reminder: incandescent light bulbs, which are hot, emit more harmful rays to the skin than LED light bulbs. Always opt for lower-temperature light sources.
