Clean the wet things and the things that touch your eyes, and stop worrying about the rest. Face brushes and sponges get washed weekly, eye brushes every second week, and the sponge gets replaced every month or two no matter how well you wash it. Throw out mascara and liquid liner at around three months, liquid foundation and cream pots within a year, and keep powders, pencils and lipsticks for years unless something about them changes. A sharpened pencil cleans itself. Dry powder is a hostile place for bacteria. A beauty fridge is a pleasant thing to own and not a hygiene measure. The rule that carries the whole subject: water, a shared applicator and an eye are where real problems come from, and almost nothing else in the bag deserves the same attention.
That is a narrower list than the internet suggests, on purpose. Makeup hygiene advice has drifted the way skincare advice did — more steps, more gadgets, more anxiety — and the effort lands in the wrong places. People sanitise a lipstick nobody else touches, then keep the same damp sponge for four months.
Where the risk sits
Three conditions make a product a problem: it holds water, it goes near an eye, or someone else has used it.
Water is the big one. Bacteria and mould need moisture to multiply, so anything wet — liquid foundation, cream blush, gel liner, mascara, a damp sponge — is somewhere growth can happen. Wet formulas are preserved for that reason, but a preservative system is a budget, not a force field. Every time a wand goes back in it carries a fresh load off your skin, and the preservative spends a little more of itself. Short clock on mascara, long clock on a pressed powder.
The eye is the vulnerable part. Dermatologists and ophthalmologists generally advise treating eye products as their own category: shorter lifespans, never shared, thrown out after an infection rather than cleaned. A red, swollen, sticky or painful eye is a doctor’s call, not a cleaning question.
Sharing is the third, and a product that is fine for one person becomes a different object the moment two faces use it. Mascara, liner and lip products are the ones worth refusing to pass around.
Brushes and sponges, on a real schedule
Anything that touches a liquid or a cream gets washed weekly. Foundation plus skin oil plus a warm room is a growth medium, and a loaded brush stops performing long before it looks dirty — bristles clump, density goes patchy, and the foundation you blame for streaking is not the problem. Powder-only eye brushes can go a fortnight; gel liner brushes join the weekly group.
The method is dull and it matters. Lukewarm water, never hot, because heat softens the glue in the ferrule. Point the head down, wet only the bristles, work a drop of gentle shampoo into your palm, swirl, rinse until the water runs clear. Squeeze ferrule to tip in a towel, reshape, then dry flat with the head off the counter edge or hanging bristles-down. Water running up into the metal is what kills brushes — a brush stood upright in a cup to dry is a brush with a loose head in a year.
Sponges are the strict one. Porous, permanently damp in use, and no amount of rinsing gets product out of the middle. Rinse after every use, deep clean weekly, replace every one to three months — sooner if it tears, stains or stops springing back. That replacement is the highest-value habit here, and the one that gets skipped because the sponge still looks fine. Where you dry it matters too, which is the argument in why the bathroom is the worst place to store makeup: a damp sponge in a steamy room never fully dries between uses.
The bag, the surfaces, the phone
The makeup bag is the dirtiest item here and the least likely to see soap. Loose powder, leaked foundation, hand cream and the inside of a gym bag all live in there, and every clean brush goes back into it. Fabric bags usually survive a gentle machine wash inside a mesh laundry bag; coated ones get wiped out with soapy water and dried open. Fortnightly is a sane rhythm, and the full method is in the makeup bag nobody washes.
Product exteriors are quick wins. Pump necks go crusty, compact hinges collect powder, lipstick caps pick up whatever is loose in the bag — a damp cloth once a month covers all of it. Palette pans that have gone shiny and hard have a film of skin oil on top; scrape it off with a tissue or a spritz of alcohol and the pigment picks up again.
Then the phone, which touches your cheek, then your pillow, then your hands, and sits on the vanity while you get ready. It need not be sterile, but wiping the screen when you wipe the counter is free. Same for the tray everything lives in — spilled powder is what makes a drawer grimy, not mysterious contamination.
The small tools nobody thinks about
The lash curler pad deserves a mention. It grooves and hardens, and a hard pad crimps lashes instead of curving them while holding mascara residue right at the lash line. Wipe it after use, replace the pad when a visible channel appears, keep the curler. The metal frame lasts a decade.
Sharpeners collect a rim of soft product around the blade that transfers onto the next pencil. Tap it out, wipe the blade with alcohol on a cotton bud, let it dry. If your pencils drag or crumble, a gummed-up sharpener is usually why.
Spatulas matter for one case: open pots. A cream blush, a balm, a thick moisturiser — fingers in a jar is how a preserved product becomes an unpreserved one, and a metal spatula ends that permanently. Tweezers need nothing beyond a wipe, since they touch hair rather than product.
How long it all really lasts
The number that governs is the little open-jar symbol marked 6M or 12M, and its clock starts the day you open the product, not the day it was made. What the symbol means and where to find it is in the open-jar PAO symbol explained. Use the table below as the working default when a product has lost its box.
| Product | Typical life after opening | Why |
|---|---|---|
| Mascara | About 3 months | Wet, pumped full of air, reintroduced to the lash line daily, and used on the most vulnerable part of the face |
| Liquid and gel eyeliner | 3 to 6 months | Same logic as mascara; gel pots are worse than pens because a brush goes back in |
| Liquid foundation and concealer | 6 to 12 months | Water-based and preserved, but pumps beat droppers and droppers beat open jars |
| Cream blush, bronzer, cream shadow | 6 to 12 months | Emulsions that separate and go tacky with age; shorter if you use fingers in a pot |
| Lip gloss | About a year | The wand travels from mouth to tube every time, and gloss holds enough water to care |
| Powder: foundation, blush, bronzer, shadow | Around 2 years | No water means no growth; these fail by hardening or losing pigment payoff, not by spoiling |
| Lipstick and lip balm | 1 to 2 years | Anhydrous wax and oil; they go off by oxidising, which you smell before anything else happens |
| Sharpenable pencils | 2 to 3 years | Every sharpening removes the used surface, so the working tip is new each time |
| Twist-up pencils and kohl | About a year on the eye | Nothing gets removed, so the same tip keeps meeting the same lash line |
| Makeup sponges | 1 to 3 months | Porous and permanently damp in use; the interior never truly gets clean |
| Brushes | Years, if washed | Retire them for shedding, permanent splay or a loose head rather than for age |
| Anything with SPF | The printed expiry date | Sunscreen filters are regulated and dated; that date beats every rule of thumb here |
The signs that beat any date
A chart gives you a default; the product has the final say. Smell is the most reliable early warning, especially on lipstick and anything oil-based — a crayon-and-old-nuts note means the oils have oxidised, and it does not go away. Separation that will not re-mix after a proper shake means the emulsion has broken. A colour shift, usually a foundation going orange or a cream blush going dull, is oxidation working on pigment. And texture: a hard shiny crust on a powder, a cream gone grainy, a mascara gone thick and stringy, a gel liner gone gluey. Any one of those, bin it, whatever the date says.
Stinging is a stop signal on its own. A product that stings today and did not last month has changed; that is not a test worth running twice.

Cinema Secrets Brush Cleaner
Dries in about a minute, which is the only reason eye brushes get spot-cleaned between shades rather than waiting for wash day
Hanging Brush Drying Rack
Holds every brush bristles-down while it dries, which decides whether the heads stay glued in. The cheapest insurance on the list
Real Techniques Miracle Complexion Sponge Multipack
Buying sponges in a pack is what makes replacing them on schedule feel normal instead of wasteful

How we picked
Everything here had to solve a problem we could name and still get used in week three, which ruled out the whole category of one-use gadgets. Where a general-purpose product does the job as well as a beauty-branded one, we listed the general-purpose one. More makeup picks work the same way.
What you can safely ignore
Sharpened pencils do not need sanitising. Sharpening is the sanitising — you cut away the surface that touched you and expose a new one. Do it before you lend a liner out and the job is done.
Powders need no special treatment either. Without water there is nothing for bacteria to live on, which is why a pressed blush lasts years while the cream version lasts months. Wiping a hardened pan is about pigment payoff, not safety.
A beauty fridge is a nice object and a poor hygiene argument. Chilling decontaminates nothing and does not meaningfully extend a preserved product’s life. Cold feels good on eye cream and metal tools, which is a real reason to want one — just not a health one. If you are working out what your setup needs, storage: start, upgrade, or overkill sorts the useful from the decorative.
UV sanitising boxes are sold as hospital-grade and behave like a light show. Ultraviolet disinfects only what it directly reaches, and the inside of a packed brush head is the definition of what it does not reach. Wash the brush instead — and wash it weekly, not daily, because daily washing wears bristles and loosens ferrules while buying you nothing.
Nobody needs to wipe down a lipstick they alone use, either. Rolling a bullet on a tissue before a friend borrows it is sensible. Doing it every morning to protect yourself from yourself is a ritual, not a precaution.
Quick answers
Do I have to throw out eye makeup after an infection? That is the standard advice from eye doctors, and it is worth following: replace mascara, liner and any eye cream you used during it, and see a doctor about the infection itself rather than treating it as a cleaning problem.
What about old makeup I never opened? Sealed products age far more slowly, but they do age. Check the printed expiry if there is one, and treat the open-jar clock as starting the day you break the seal.
If I Were You
If you have had an eye infection replace every eye product you used in the fortnight before it — mascara, liner, the eye brushes if they are cheap ones — and see a doctor rather than deciding on your own that it has resolved. This is the one place where throwing things out is the cautious, correct move.
If you share makeup with a sister or a friend draw the line at wet and at eyes. Powders, brushes you wash, and a lipstick rolled on a tissue are fine to pass around. Mascara, liquid liner and gloss are not, and disposable wands solve the mascara case permanently.
If you only do one thing replace your sponge. It is the item most likely to be old, most likely to stay damp, and the only one where cleaning cannot fully fix the problem.
If your makeup lives in the bathroom move the wet products and the sponge out first — heat and steam shorten the life of emulsions and keep porous things damp. Powders and lipsticks can stay put.
If your foundation has started breaking you out check the bottle’s age and the brush before blaming the formula. A year-old foundation applied with a brush washed twice since you bought it is two problems pretending to be one.
The habit that carries the rest
Pick a day. Wash the face brushes and the sponge, wipe the curler pad and any crusty bottle neck, and once a month turn the bag out and check the wet products for smell and separation. Fifteen minutes, fortnightly at worst. That rhythm does more than any sanitising device or fridge ever will, and it earns you the right to ignore everything else with a clear conscience — which is the best thing our makeup coverage can give you.
