How to Sanitise Makeup Products: powders, creams, lipsticks, pencils, liquids — and the cross-contamination rules that make sanitising unnecessary
Every product in a working kit is handled one of two ways: it is sanitised between clients, or it is never touched by a client in the first place — decanted onto a palette or used with a disposable. The second way is better, because it removes the risk at the source; the first is what makes the products that must be touched safe. The overall standard is in Makeup Hygiene for Professionals; tools in Brush Cleaning and Care; the busy-morning routine in Multi-Face Mornings and Working With an Assistant.
The two systems
Decant and dispose. A clean metal spatula takes the amount for one face from the container onto a clean palette (a steel plate, a disposable palette sheet, or the back of a gloved hand); the artist works from the palette; the container is never touched by a used brush; leftovers are discarded, never returned. Disposable applicators — sponges, mascara wands, lip applicators, spoolies, cotton buds — are dipped once and binned. Under this system most containers never need sanitising, because nothing that has touched skin has touched them.
Sanitise between clients. For products that must be applied from the container — pressed powders, pencils, bullet lipsticks in some workflows — the surface is cleaned with 70% isopropyl alcohol after every client.
A working kit runs both: decanting for everything that can be decanted, sanitising for the rest.
By format
| Format | Can it be sanitised? | How | Better practice |
|---|---|---|---|
| Pressed powders (eyeshadow, blush, bronzer, powder foundation) | Yes | Mist with 70% IPA until the surface is wet; leave to dry fully (minutes); wipe the case; do not saturate repeatedly — the pan can crack over time | Use a clean brush per face; spot-clean between faces; scrape a thin top layer if a pan is visibly soiled |
| Loose powders | No (in the jar) | — | Tap out onto a palette or tissue; never dip a brush into the jar |
| Cream products (blush, contour, concealer pots, cream shadow) | Surface only | Scrape the top layer with a clean spatula, wipe the pan's edge, mist lightly, let dry; never spray into the product (separation) | Decant per face with a spatula; work from the palette |
| Liquid foundation (pump) | The pump/nozzle | Wipe the nozzle with IPA; pump onto the palette, never onto the skin or a brush | Pumps are the safe format; pour-bottles are wiped and poured |
| Concealer with a doe-foot | No | — | Scrape a small amount onto the palette with a spatula; the wand never touches skin; or use a pot with a spatula |
| Lipstick (bullet) | Yes | Mist the exposed bullet and let it dry; or trim 2–3 mm with a clean blade and wipe; apply with a disposable applicator or a clean lip brush | Scrape a portion onto the palette with a spatula and apply with a brush — the bullet never touches lips |
| Liquid lipstick, gloss with a wand | No | — | Disposable applicator dipped once, or the product scraped out onto a palette; never the wand on lips |
| Lip liner, eye pencils, kajal | Yes | Sharpen before every client (the sharpener wiped with IPA); wipe the tip with IPA | Sharpen per face; the sharpener cleaned |
| Gel liner in a pot | Surface | Scrape the top with a spatula; mist lightly; dry | Decant a small amount; a clean brush per face |
| Mascara | No | — | A fresh disposable wand per dip, never re-dipped; or a single-client tube; never a client's own tube on another client |
| Liquid liner (pen or brush-in-bottle) | No | — | Single-client units, or gel liner decanted with a disposable brush |
| Lash glue | The nozzle | Wipe; dispense onto a palette or the back of the hand | A dot on a palette per face |
| Setting spray | The nozzle | Wipe; mist at arm's length, never touching | — |
| Brushes and sponges | Yes | See the brush guide | Disposable sponges per face; a second set of base brushes |
| Skincare, primer in a jar | No (in the jar) | — | Spatula out onto a palette; pumps preferred |
The alcohol itself
70% isopropyl alcohol, in a fine-mist spray bottle, refilled from a sealed source; the working bottle labelled. Not 99% (it evaporates before it disinfects), not surgical spirit with additives, not perfumed "sanitiser" gels. Sprayed onto surfaces and tools, never into products, never near the eyes of a client, and given time to dry — a wet pan touched by a brush is neither sanitised nor usable.
What alcohol damages
Creams and liquids can separate when alcohol is sprayed into them; some cream formulas dry and crack on repeated surface spraying; pressed powders develop a hard film if saturated too often; natural-hair brushes dry with frequent alcohol (soap and water are their deep clean). The answer in each case is the same: decant so the container needs less.
The cross-contamination rules
- Decant per face with a clean spatula onto a clean palette.
- Disposables per face, dipped once, binned.
- Brushes spot-cleaned with IPA between faces; a second set of base brushes; deep-cleaned weekly.
- Pencils sharpened per face; the sharpener wiped.
- Nothing returns to a container.
- Hands sanitised between faces; gloves for any broken skin.
- Skin checked before starting — infection, open lesions, an inflamed eye stop the work on that area.
- A bin at the station; a wipe-down of the table between faces.
- Products dated; expired ones out.
- The assistant owns the cleaning on a multi-face morning so the lead never works dirty.
The kit layout that makes it easy
Spatulas (several, in a jar of IPA); palette sheets or steel plates; a disposables box open on the table (sponges, wands, lip applicators, spoolies, cotton buds); the IPA spray; a sharpener; a bin at knee height; products in pumps and pots rather than wands where a choice exists. The kit itself is in Professional Makeup Kit Essentials.
From Chhaya Yadav's experience
Observations from bridal and teaching work in Jaipur — professional observations, not statistics.
- Decant everything is the rule that made sanitising almost unnecessary in my kit — the containers are never touched by a used brush.
- One wand, one dip, bin for mascara — I show students the wand going in the bin before I show them the lashes.
- The lipstick bullet never touches a bride; a spatula and a brush, every time.
- Spraying alcohol into a cream blush is how a student learned that "sanitise" and "ruin" are one spray apart.
Frequently asked questions
Which alcohol sanitises makeup, and how? 70% isopropyl alcohol in a fine spray — the water content gives it contact time; 99% evaporates before it works. Powders are misted until the surface is wet and left to dry fully; cream surfaces are scraped clean first, then misted; lipstick bullets are misted or trimmed; pencils are sharpened. Alcohol is never mixed into a product or sprayed into a liquid.
Can every product be sanitised? No. Mascara, liquid liner, lip gloss in a tube, liquid lipstick and anything with a wand or a doe-foot cannot be sanitised in the container — the wand goes back into the reservoir. They are used only with disposable applicators dipped once, or decanted onto a palette, or bought as single-client units. Cream formulas can separate if alcohol is sprayed into them; the surface is scraped and the product decanted instead.
What is decanting and why does it matter? Taking the amount needed for one face out of the container with a clean spatula onto a clean palette, so the artist works from the palette and the container is never touched by a brush that has touched skin. It removes most cross-contamination at the source and means the container needs no sanitising at all. It is the single most important kit habit.
How is cross-contamination prevented on a multi-face morning? Decant per face; disposables (sponges, wands, lip applicators, spoolies) per face and never double-dipped; brushes spot-cleaned with 70% IPA between faces and a second set for base brushes; pencils sharpened per face; hands sanitised between faces; nothing returned to a container; a bin at the station; an assistant who owns the cleaning. The routine is the protection.
Key takeaways
- Two systems: decant-and-dispose for everything that can be, 70% IPA for what must be touched.
- Powders misted and dried; creams scraped then misted; bullets misted or trimmed; pencils sharpened; wands never shared.
- Never spray alcohol into a product; never return product to a container.
- Disposables per face, a second brush set, hands sanitised, a bin at the station, an assistant who cleans.
