Screen skin, honestly

We sell an eye cream with the word digital in the name, so we are not a neutral party here. That is exactly why this note is worth writing: the marketing around screens and skin has run considerably ahead of what anyone can demonstrate, and we would rather be straight about which parts we believe.

The popular version says the visible blue light emitted by phones and laptops generates free radicals in skin and contributes to pigmentation and ageing. The studies usually cited are real. They are also, almost without exception, run at intensities far above what a screen produces — closer to standing outdoors than to sitting at a desk.

The sun puts out vastly more visible blue light than your monitor, by orders of magnitude. If blue light at screen intensity were a significant driver of pigmentation, a window would be the problem long before a laptop was. There is more credible evidence for visible light affecting melanin-rich skin — but again, at daylight intensities.

Your screen is not irradiating your face. What it is doing is keeping you awake, still, and unblinking for nine hours.

• Blink rate collapses. Focused screen work cuts blinking by roughly half, which dries the eye surface and the thin skin around it. This one is well documented and it is why the eye area feels worse by evening.
• The air is wrong. Air conditioning, ducted heating and a sealed office all pull ambient humidity down. Dry air draws water out of the surface all day long.
• You are frozen in one expression. Hours of squinting at small type and holding a brow position leaves the area around the eyes tight and tired-looking by evening.
• You are not sleeping. Screens push bedtime later. Short sleep shows up under the eyes faster and more visibly than almost anything else you can do to your face.
• You forgot to drink anything, and you had a fourth coffee instead.

None of that is exotic. All of it is why the skin around your eyes looks worse on a Thursday than it did on a Sunday, and none of it needs a blue-light filter to explain.

Push the screen back to arm’s length and raise it so you are looking slightly down — that alone widens the blink. Put something wet in the air if the room is dry. Take the twenty-second look out of the window every half hour; it is free and it works better than most things that are not. Then, and only then, is there anything for a cream to do.

Which is where ours comes in, and the claim stays small: it holds water in a very thin area of skin and improves how tired that area looks. It does not filter light, it does not undo a short night, and no eye cream sold by anyone does either.
