#SEEKSAYS: The Truth About Blue Light
BLUE LIGHT?
It is a high-energy, short-wavelength light (HEV) that’s part of the visible light spectrum (what the human eye can see).
There are two forms:
NATURAL
(FROM THE SUN)
ARTIFICIAL
(FROM GADGETS)
BLUE LIGHT AND OXIDATIVE STRESS
Studies show that blue light can induce oxidative stress in the skin and can potentially harm the skin through free radical generation, causing photo aging, loss of firmness, pigmentation, and an increase in fine lines.

NOTE: These effects have been observed in skin exposed to natural blue light, unprotected sun exposure, and not artificial blue light.
WHAT’S THE DIFFERENCE?
Artificial blue light is significantly weaker than blue light from the sun.

IS BLUE LIGHT-SPECIFIC SKINCARE NECESSARY?
#SEEKSAYS: NOPE!
Because artificial blue light - from screens - is significantly weaker, normal usage is not enough to trigger harmful effects on the skin. Skincare aimed at preventing blue light damage is more of a marketing tactic with inconclusive evidence.
OUR ADVICE
- Add antioxidants into your routine to fight any oxidative stress
- Wear sunscreen whenever you're outdoors or near windows
- Apply a blue light screen protector on your gadgets to protect your eyes
