The Skin Microbiome: Seven Everyday Habits That Wear It Down — and What Shows Up Years Later

Most of the wear on the skin's microbiome is done by people trying to take care of their skin. Seven habits a careful person does on purpose, what they add up to over years, and the one thing to take away before adding anything.

Most of the wear on the skin’s microbiome is done by people trying to take care of their skin.

That is the whole uncomfortable fact of it. The community of microorganisms living on your face has been there since the day you were born, doing its quiet work, and the person most likely to disturb it is a woman with a ten-step routine and the best of intentions.

Neglect isn’t the problem. Diligence is.

What It Is, in a Sentence

Your skin carries its own population of bacteria and other microbes, the way your gut does — a resident community that has lived on human skin for as long as there has been human skin. What exactly it does for you is still being worked out. That it’s there, and that it would rather not be scrubbed off every night, is not.

What follows is not a list of sins. Every one of these is something a careful person does on purpose.

The Seven Habits

Washing until it squeaks

Squeaky-clean skin is skin with nothing left on it, including the things that were supposed to stay. The feeling of tightness after cleansing is not cleanliness. It is a report.

Hot water, because it feels better

It does feel better. It also strips the surface far faster than lukewarm does, and the face is the one place most people wash with water they would not put a baby in.

Exfoliating on a schedule instead of on evidence

Twice a week is a habit, not a diagnosis. Physical scrubs and acids both do their job by removing the top of the skin — which is a fine thing to do occasionally and a strange thing to do to a surface that hasn’t asked for it.

The wipe on the nightstand

A makeup wipe is a solvent on a cloth, applied with dragging, usually to the most delicate skin on the face, usually in a hurry. It is the single most efficient way to undo a day of good behavior in forty seconds.

Stacking actives because each one was recommended

Each one probably was. But an acid in the morning, a retinoid at night, vitamin C on top, and a peel on Sundays is not a routine. It is a siege, and the surface being besieged is the same one that was meant to host something.

Changing products every six weeks

Every switch is a new set of preservatives, a new pH, a new texture, and a new adjustment. Skin that never gets to settle never gets to show you what it would look like settled.

Rubbing, all day, without noticing

Allergy season, tired afternoons, contact lenses, the pad at 11:40. The under-eye gets more friction than any other patch of the face — and it shows there first.

The Part That Arrives Later

None of these does anything visible on Tuesday, which is exactly why they last. The bill comes over years, and it looks like this:

What people describe, years in

“My skin got sensitive.” Things that used to be fine now sting. New products are a gamble. This is usually described as a change in the skin, and it is more often a change in what was done to it.

“It looks tired even when I’m not.” A surface that is constantly being reset never gets to look rested. Dullness, in a lot of cases, is skin that has been asked to start over too many times.

“Nothing works anymore.” Not because the products stopped working. Because the surface they were meant to work with has been stripped, rebuilt, and stripped again until it can’t tolerate the things that would help it.

The frustrating part is that all three tend to send a person back to the shelf for something stronger — which is how the habit that caused it ends up sold back to her as the answer.

What Not to Take From This

Not “stop cleansing.” Sleep in mascara and you will have a different article’s worth of problems. Not “never exfoliate.” Not “actives are bad.” Retinol, vitamin C and the rest are excellent, and we use them ourselves.

Take this instead: the face is a surface that is already occupied, and the job of a routine is to work with what lives there, not to clear the site every night and start again.

Keep this oneBefore adding anything to your routine, take one thing away and wait a month. Most skin that “needs something” is skin that needs to be left alone long enough to show you what it’s actually doing.

Which Is Why We Built a Corner of the Jar for It

The under-eye takes more of all seven than any other part of the face, which is why one corner of SKINWIT THE EYE CREAM was built for the skin’s own community rather than in spite of it — six named species alongside sea kelp and exosomes, at medical-grade doses. We wrote about the six, and about what the word “probiotic” does and doesn’t mean on a jar, because that deserved its own page.

Of our two eye creams it is the one that asks the least of the skin it lands on, it was made for every skin tone, and it comes with the Empty-the-Bottle Guarantee: finish the jar, and if your skin disagrees, it’s on us.
