Daily screen exposure is the modern environmental stressor we don’t see. But our skin does.
High-energy visible (HEV) blue light emitted from computer and cell phone screens can contribute to oxidative stress in the skin, leading to dullness and loss of firmness over time.
Designed for life in front of screens, this antioxidant-rich serum is powered by Pepha®-Age, a patented ingredient clinically studied for blue light defense. Consider it as your Digital "SPF"(screen protection factor).
Lightweight and easy to layer, it delivers the blue light protection that a typical sunscreen doesn't while actively brightening skin tone.
Sensitive skin friendly. Dermatologist-approved. Made in the USA.

"What makes Matter of Monday's Anti-Blue Light Brightening Serum exceptional is its dual-action formulation. It not only protects the skin from digital pollution but also supports its natural repair processes overnight. In my practice, this kind of protection against blue light is the missing link in many skincare routines and this serum finally fills that gap."

Great addition to my skincare routine. I spend a lot of time using my computer I was looking for extra blue light protection (besides the one provided by antioxidants) this serum has Pepha-Age that helps turning this into your digital SPF. Love the lightweight texture, that doesn't have a scent and it sinks so fast, pairs well with all my other skincare without peeling or leaving a sticky finish.
As someone who spends a lot of time in front of computer screens, this blue light serum has become my daily go-to. I use it along with my blue light glasses. It has a smooth, lightweight texture, which I really love.
The serum is lightweight and has no scent. It's a lovely product.
I like this product with all my soul. Perfect lightweight texture and it’s soo good for my oily skin. Highly recommend!
I've been wearing blue light glasses because I'm aware of the blue light damage. So glad to have found this blue light serum. I like its ingredients are rich in antioxidants. It feels very soft and smooth on my face. Love it!
