Lip scrubs sweet, sugary exfoliants that buff away dry lips are a popular, giftable product, but they sit in a particularly sensitive category: lip products, which are partly ingested. That changes the safety picture in important ways, and a lip scrub is a cosmetic needing a CPSR. This guide explains what the assessment covers for lip scrubs.
For the fundamentals, see our guide to what a CPSR is. Here we focus on lip scrubs, which share considerations with lip balm and scrubs.
Lip products are partly ingested
The defining feature of any lip product is that it is applied to the lips and, inevitably, partly ingested licked off, eaten with food, swallowed in small amounts. With a lip scrub, which is often literally licked or wiped off, this is especially true. This means the safety assessment must consider oral exposure, not just skin contact, and every ingredient must be safe to be taken into the body in small amounts.
This ingestion factor is why lip products are treated with particular care and why some ingredients allowed elsewhere are not appropriate for the lips. A lip scrub designed to be sugary and tempting only heightens the likelihood of ingestion. Recognising that you are making an effectively part-edible product is the foundation of assessing it correctly.
Colourants must be lip-permitted
Because lip products are ingested, colourants are tightly controlled. Only colourants permitted for use in lip products those on the approved list cleared for this use, taking ingestion into account may be used. Many colourants allowed in other cosmetics are not permitted for the lips, and craft or non-cosmetic colours are entirely unsuitable. Using a non-permitted colourant in a lip scrub is a serious compliance failure.
This is one of the most common pitfalls for lip products: reaching for a pretty colour that is not cleared for lip use. The assessment checks every colourant against the permitted list and its conditions for lip products specifically. Sourcing cosmetic-grade, lip-approved colourants is essential, and our guidance on ingredient annexes explains how the colourant list works.
Gentle exfoliants usually sugar
Lip scrubs exfoliate with particles, and for lips these must be gentle, since lip skin is thin and delicate. Sugar is the classic choice precisely because it is gentle and, helpfully, dissolves reducing both harshness and any ingestion concern, since it simply melts away. Salt is used too but can sting, especially on cracked lips. As with all scrubs, plastic microbeads are banned, so the exfoliant must be a compliant natural material.
The assessment considers the exfoliant's gentleness and suitability for the lips, and confirms no plastic microbeads are used see our microplastics guide. Sugar-based lip scrubs are popular partly because they neatly sidestep both the harshness and microplastics concerns, dissolving safely as they are used.
Anhydrous, but watch real-world water
Most lip scrubs are anhydrous sugar suspended in oils, butters and waxes, with no added water so they generally do not need a traditional preservative. The sugar at high concentration also has some self-preserving effect. This makes basic lip scrubs relatively simple on the preservation front, which suits their often small-batch, natural positioning.
However, lip scrubs are typically applied with fingers from a small pot, which can introduce water and microbes, and they are used on wet lips. The assessor considers this real-world use; where water exposure is significant, preservation may need revisiting. Any lip scrub that does contain water needs proper preservation and a challenge test. Our preservatives guide covers the principles.
Flavour and sweeteners
Lip scrubs are usually flavoured and sweetened to be pleasant on the lips vanilla, fruit, mint and the like. Flavourings (shown as “Aroma” on the label) and any sweeteners must be safe for this part-ingested use and used at appropriate levels. As with fragrance, flavourings can contain declarable allergens, and they need to be food-safe-grade materials suitable for lip products, not random flavour oils.
The assessment checks flavourings and sweeteners for suitability and level, mindful of ingestion. Because the whole appeal of a lip scrub is often its tempting flavour, it is doubly important these ingredients are appropriate and safe to eat in small amounts. Using materials intended and cleared for lip use is the safe route.
Essential oils on the lips
If essential oils are used for example mint or citrus they need particular care on the lips, both because of ingestion and because some are unsuitable or need strict limits for lip products. Citrus oils raise the usual phototoxicity question, and strong oils like cinnamon or clove can be irritating to delicate lip skin. The lip context calls for conservative, well-chosen essential-oil use.
The assessment treats essential oils in lip products with appropriate caution, checking levels against limits for this sensitive, ingested use. Our essential oils safety guide gives the background. For lips, less is generally more, and gentle, suitable flavourings are often a better choice than potent essential oils.
Labelling small lip products
Lip scrubs come in small pots, which makes fitting the mandatory labelling INCI list, RP details, net quantity, durability or PAO, batch code, function, warnings and allergens a challenge. The rules allow some information on accompanying material (a leaflet or attached tag) where the container is too small, which is often the practical solution for tiny lip products.
As always, small size is not an excuse to drop required information. Careful label design, peel-back labels, or accompanying leaflets let you fit everything compliantly. Our ingredient list and label warnings guides cover what must appear; the craft is fitting it onto a small pot.
Common lip scrub mistakes
The most common and serious lip-scrub mistake is using non-permitted colourants reaching for a pretty mica or a craft colour that is not cleared for lip use, forgetting that lip products are ingested and tightly controlled on colour. A second is harsh or non-dissolving exfoliants coarse salt or rough particles on delicate, sometimes cracked lips when gentle, dissolving sugar is far better suited. A third is unsuitable flavourings, using random flavour oils rather than materials appropriate and safe for a part-ingested lip product.
Other slips include over-using potent essential oils (cinnamon, clove or citrus) on the lips, assuming no preservation is ever needed despite finger-and-water contact, and dropping mandatory labelling because the pot is small. Each is avoidable: use lip-permitted colourants, choose gentle dissolving exfoliants, use suitable flavourings, go easy on essential oils, consider real-world water exposure, and fit full labelling via design or a leaflet.
Underlying all of these is the single key insight: a lip scrub is partly eaten. Once you formulate with ingestion front of mind every colour, flavour and ingredient safe to take into the body in small amounts the right choices tend to follow. Sugar-based, lip-approved, lightly flavoured scrubs are popular precisely because they sit comfortably within these constraints while still being a delightful product.

Does lip scrub need a CPSR?
Yes. A lip scrub is a cosmetic needing a CPSR, PIF, Responsible Person, notification and compliant labelling. Because lip products are partly ingested, the assessment is especially careful.
Why are lip products treated differently?
Because they're applied to the lips and partly ingested licked or wiped off and swallowed in small amounts. The assessment must consider oral exposure, and every ingredient must be safe to take into the body in small amounts.
Can I use any colour in a lip scrub?
No. Only colourants permitted for use in lip products may be used, because of ingestion. Many colourants allowed in other cosmetics aren't cleared for the lips, and craft or food colours are unsuitable.
What exfoliant should I use in a lip scrub?
Sugar is the classic choice because it's gentle and dissolves, reducing harshness and ingestion concerns. Plastic microbeads are banned, so the exfoliant must be a compliant natural material suited to delicate lip skin.
Does a lip scrub need a preservative?
Most are anhydrous (sugar in oils and butters) and generally don't, with sugar adding some self-preserving effect. But finger application and wet lips can introduce water, so the assessor considers real-world use, and any water-containing scrub must be preserved and challenge-tested.
Are flavourings and sweeteners a concern?
They must be safe for part-ingested use and used at appropriate levels, using materials suitable and cleared for lip products. Flavourings can also contain declarable allergens, which the assessment checks.
How do I label a tiny lip scrub pot?
Use careful design, peel-back labels or an accompanying leaflet to fit the full mandatory information. Small size doesn't allow dropping required details the rules permit some information on accompanying material.
Can I use mica or pigments to colour a lip scrub?
Only if they are colourants permitted for use in lip products and used within their conditions. Many colourants and craft micas aren't cleared for the lips, because lip products are ingested, so each must be checked against the permitted list.
Are essential oils safe in a lip scrub?
They need extra caution, because lip products are part-ingested and lip skin is delicate. Citrus oils raise phototoxicity questions and strong oils like cinnamon or clove can irritate, so conservative, suitable use is best.
