How do you use a blue light filter primer correctly?
A blue light primer is applied like a regular primer—after skincare and before makeup. Take a small amount and spread it evenly over your face, especially where you’re exposed to a lot of screen light (usually the entire face). Let it absorb briefly before applying foundation or other products.
Important:
It does not replace your skincare routine but serves as an additional protective and preparatory step designed to shield the skin from digital light while also making your makeup last longer.
