When many clients begin building a makeup brush brand, one of the first things they naturally think about is a brush set.
That makes sense.
Compared with single brushes, a set feels more complete and more like a formal product line.
Visually, it is easier to communicate a sense of brand identity. In pricing terms, it also naturally sits higher than a single brush, so it can seem like an easier way to raise average order value.
But if you really look at it from the perspective of product development and sales, you quickly realize this:
designing a makeup brush set is actually very easy to get wrong.
Because a brush set and a single brush do not follow the same product logic.
With a single brush, the customer can choose exactly what she needs.
She knows what she is missing, so she buys that one brush.
In that situation, the demand is usually clearer, the purchase intention is more focused, and the psychological expectation is easier to satisfy accurately.
A set is different.
A set is not something the customer builds for herself, one brush at a time.
It is a decision the brand makes for her.
She does not get to remove the brushes she does not want. Her choice is simply whether to buy the set or not.
That means a set naturally carries more risk:
- the selling price is higher, so the payment pressure is higher
- if even one or two brushes feel unnecessary, the customer will feel she paid for something she did not really need
- if some brushes require more skill, ordinary users may not be able to use them well, and that can easily lead to disappointment
- even if the whole set looks complete, once the customer starts thinking “I do not really use these one or two brushes,” the overall shopping experience begins to crack
So from a product design point of view, the most important question in a set has never been “how many pieces should be included.”
What really matters is:
- whether it fits a certain price range
- whether it is easy to sell
- whether it truly covers high-frequency needs
- whether it makes the customer feel the money was well spent
That is exactly why I have always believed this:
the best brush set is not the one with the most pieces. It is the one with the clearest purpose and the easiest value for the customer to understand.
So this article is not really about listing what a brush set “usually includes.”
What it really wants to answer is:
How should a brand actually make decisions when designing a brush set?
And why do some sets look complete but still sell poorly, while others have fewer pieces and feel much more solid as products?
A Brush Set Is Not Just a Group of Brushes. It Is a Buying Decision Made for the Customer
If there is one layer of set design that is most often overlooked, it is this:
a brush set is not simply a group of brushes. It is a buying decision the brand is making on behalf of the customer.
That may sound simple, but it explains very clearly why sets are easier to get wrong than single brushes.
With a single brush, the customer buys based on a specific need.
She knows she needs a foundation brush, or that she is missing a blush brush, so the decision is clear.
A set is not like that.
Once a set has been designed, the customer cannot simply remove the brushes she does not want.
She is facing a full combination.
That means the brand has to think more carefully than it would with a single brush:
- is this whole set really right for the same kind of user?
- do these brushes actually belong together?
- will the customer feel that some brushes are valuable, while others are just filler?
- will she begin to question the whole set because one or two brushes feel unnecessary, confusing, or difficult to use?
That is why I say the logic of a set is different from the logic of a single brush.
A single brush is closer to precise customer selection.
A set is much closer to a structured decision made by the brand.
And because of that, when a set is not designed clearly enough, the customer does not experience “more choices.”
She experiences something more like:
I think I paid for things I did not really need.
That becomes especially dangerous in higher-priced sets.
Because the higher the price, the more sensitive the customer becomes to whether the set feels worth it.
If she discovers that some brushes are redundant, low-frequency, or difficult to understand, that psychological gap becomes much larger.
So the starting point of set design should not be:
How many brushes do I want to include?
It should be:
What kind of buying decision am I making for the customer?
The Starting Point of a Brush Set Is Not Piece Count, but Core Use Scenario and High-Frequency Needs
Many clients begin by saying:
I want to make a 12-piece set.
I want to make a 15-piece set.
I want a set that looks very complete.
But from a designer’s and factory’s point of view, a mature starting point should not be the number of pieces.
Because piece count itself does not tell you whether the set will actually work.
A more reasonable starting point is:
what core use scenario the set is supposed to serve
and
which functions are genuinely high-frequency, necessary, and easy for the customer to recognize as valuable
So from our development perspective, the first thing we care about is always this:
does this set already cover the most essential and most frequently needed steps in the full makeup process?
In other words, if the customer is not using other brushes, can she still complete the look she wants with this set?
Only after that basic framework is clear does it make sense to discuss piece count, material, or shape.
From experience, a more practical order of judgment usually looks like this:
core function / core use scenario → price range → product positioning + target customer
That order matters.
Because if the core demand is still vague, then even if the materials are chosen well, the shapes are refined carefully, and the set has many pieces, that still does not mean anyone will buy it.
You can position it beautifully, but if no precise customer is willing to pay for it, it has no real value.
That is why I think the first set for a new brand should not begin with scale. It should begin with clarity. The clearest way to think about set design is to start from core use, price point, target user, and hero brushes, and only then define the final structure.
- who is this set for?
- what kind of makeup does she actually do most often?
- which brush functions will she really use at a high frequency?
- what exactly will make her feel this set is worth buying?
- within what price range will this set feel reasonable to her?
Those questions matter much more than the number of pieces.
A Set Only Works When Every Brush Has a Clear and Independent Value
If we temporarily set aside business conditions like budget, brand positioning, and target user, and only look at whether a set works as a product, then one principle matters a great deal:
every brush in the set should have a clear and independent value inside the overall makeup process.
That means no brush should be there just to fill space.
Each one should be carrying a real and understandable function.
A simple but practical example would be this.
If we think about a relatively complete everyday makeup routine, a set is more likely to feel solid when its basic framework includes functions such as:
- one foundation brush
- one multifunction concealer brush
- one or two eyeshadow placement/detail brushes
- one medium blending brush
- one smaller detail brush
- one brow / eyeliner brush
- one blush brush
- one contour brush
- bronzer (optional)
- one setting or powder brush
The most important thing here is not that these exact names must appear in every set.
What matters is the logic they represent:
- each brush should have a clear function
- there should not be heavy overlap between brushes
- the usage flow should feel natural
- the logic from base makeup to eye makeup to setting should make sense
- there should not be low-frequency or hard-to-explain shapes included just to increase the count
That point is especially important.
Because the biggest risk in many brush sets is not that they contain too few brushes.
It is that the customer cannot clearly understand why those brushes are different from one another.
Once that happens, the value of the entire set begins to drop.
A Set Is Not Better Just Because It Is More Complete. Many “All-in-One” Sets Are Harder to Sell
This is one of the most common and most serious mistakes I see.
A lot of clients naturally fall into this pattern of thinking:
If I am making a set, then should it not cover as many functions as possible?
Should it not include every shape the customer might ever need?
Would 10 pieces, 12 pieces, 15 pieces, or even more than 20 pieces not feel more professional, richer, and more worthwhile?
That logic sounds reasonable at first.
But in reality, it is very dangerous.
Because once you try to force “every possible function” into one set, you easily fall into a major trap:
you think you are building a complete, all-purpose set, but in reality you are creating confusion and buying resistance.
This problem is especially obvious with eye brushes.
Eye brushes can absolutely be made very rich and very detailed.
Different shapes, different sizes, different thicknesses, and subtle structural variations do create real technical differences.
From a professional point of view, that richness can indeed make the set look very sophisticated.
But professionalism and sellability are not the same thing.
If you create too many eye brushes with very small differences, and in the end even you cannot explain those differences clearly, the customer is even less likely to understand them.
What she will feel is something more like:
These all seem kind of similar.
And once the customer starts feeling that, the richness and sophistication you wanted to communicate begin to turn into something else in her mind:
complexity
confusion
uncertainty about whether this is really worth buying
That is why, from a marketing and sales point of view, very large, very dense, and excessively “complete” sets are often not an advantage. They are a burden.
Which is exactly why I say:
a set is not better because it covers more. It is better when its purpose is clearer.
If you are selling brushes individually, then I absolutely encourage bolder creativity and more subtle variations, because customers can choose according to their personal needs.
But if you are designing a set, and the brand is making the decision for the customer, then restraint becomes far more important.
For a New Brand, the First Set Should Be Built Through Reduction, Not Expansion
If there is one principle I would most want a new brand to remember about set design, it would be this:
do not try to make the first set too big.
Because the most important job of a first set is not to prove that your brand can do everything.
Its job is to make the customer willing to buy it—and to feel it was worth buying afterward.
That means the first set should not be built around total completeness.
It should be built around:
- high-frequency needs
- clearly defined hero brushes
- lower cognitive burden
- lower buying pressure
- brushes whose value is easy to feel and easy to explain
But before even that, there is another question that has to be confirmed first:
what is the budget, or what is the final selling price range?
That point is extremely important.
Because if the client has not even clarified the target budget, the intended wholesale cost, or the final selling range, then every later discussion about material, shape, piece count, and craftsmanship remains very unstable.
Very often, clients can also tell us more about their brand positioning and target customer.
That helps tremendously in deciding:
- what kind of materials make sense
- what kinds of shapes are easier for that market to accept
- how many brushes are actually reasonable in one set
- which functions absolutely need to stay
- which functions can be developed later as separate products
So for a first set, the more mature logic is not:
“I want a 12-piece set, now let’s fill it.”
It is:
“I want to define the budget and price band first, and then decide how many brushes actually make sense within that structure, and which functions are truly worth keeping.”
That is why I always say:
for a new brand, the first set should be built through reduction.
Reduction is not conservatism.
Reduction is what makes the product clearer, easier to sell, and easier for the customer to feel was worth the purchase.
Different Users and Selling Scenarios Do Not Follow the Same Set Logic
Another point that gets ignored very easily is this:
many people assume that “a brush set is a brush set,” as if the logic does not really change depending on who it is for.
But in reality, different users and different selling scenarios can require very different kinds of sets.
Retail users care more about high-frequency use and value for money
For the general retail user, the most important things are usually not extreme variety or technical perfection.
What matters more is:
- whether the set covers what she actually uses
- whether it is easy to understand
- whether it is easy to handle
- whether the experience feels good
- whether the money feels well spent
In other words, retail users care much more about high-frequency brushes, low learning burden, and an overall sense of buying rationality.
Professional users care more about detail and control
Professional users, especially makeup artists, are completely different.
They demand much finer control, pursue more exacting results, and are much more willing to pay for specific materials and more specialized shapes.
In that context, more segmented and more technical brush types really do have value.
So if a set is meant for the professional market, it can absolutely become more complex, more detailed, and more refined.
But only if you are very clear about who you are selling it to.
Gift-oriented sets often depend more on luxury perception than on functional detail
Gift sets follow another logic again.
In these products, the brushes themselves still matter, of course. But very often, the customer is not first asking, “Is this one for contour or bronzer?”
What she sees first is:
- does the product feel luxurious enough?
- does the material look refined?
- does the packaging feel impressive enough?
- does the whole set feel suitable as a gift?
That means in a gift-oriented set, the sense of luxury and completeness often matters even more than fine distinctions in functional design.
KOL or collaboration sets depend heavily on content and personal preference
If the set is tied to social media or a KOL collaboration, then another variable enters the picture.
In those cases, the factory and designer can certainly make recommendations, but in the end, the client’s and the KOL’s own preferences still matter a great deal.
Because what the KOL likes, how she uses brushes, and how she is willing to present them all affect whether she can actually convert her audience.
So once again, the real logic remains:
everything still has to begin with what can actually be sold.
That is why I always think a brush set is never just a product decision. It is the result of:
product logic + selling scenario + user understanding
working together.
A Strong Set Does Not Spread Cost Evenly. It Makes Shape, Hair, Price Point, and User Type Work Together
A mature brush set is never built through even allocation. It is not a case where every brush receives the same material level, the same cost weight, or the same development priority. A more realistic approach is to let shape, hair, price point, and user type work together.
As explained in How to Choose Makeup Brush Shapes, shape should be defined by function, placement, and application logic rather than by appearance alone. And as discussed in How to Choose Makeup Brush Hair, material choice should follow finish, formula, market acceptance, and cost structure rather than the material name alone.
That means different positions inside the set should carry different layers of value.
Based on the experience you shared, if we temporarily ignore budget and target user and only look at shape and hair as a framework, then a more mature structure usually looks something like this:
- smaller and medium powder brushes, where the experience difference is easiest to feel—such as eye brushes and blush brushes—are often the best places to prioritize natural hair
- large face brushes, such as foundation, contour, bronzer, and sculpting positions, are more often and more reasonably handled with synthetic fiber, provided that the blending ratio and shaping are done correctly
This is a very mature strategy.
Because it is not an even distribution. It is a layered balance between experience and cost.
In other words, the positions in the set that are most capable of creating a visible difference in feel and finish should receive that extra value.
And the larger, higher-hair-volume positions—where synthetic fiber can still deliver a good result at a much more realistic cost—should be handled more economically but still intelligently.
That is why I always believe:
a set feels premium not because every brush is overbuilt, but because the set knows exactly where experience needs to be strongest.
Sometimes the Best Set Is Not Bigger. It Is Better Structured
This, to me, is one of the clearest places where professional experience shows.
Many clients begin by sending a large number of reference images and asking for a direct copy.
Sometimes that means 20 or more brush images, all intended for one “complete” set.
If a factory simply follows that request mechanically, then yes, the set can be produced.
But that does not mean it is the best product structure.
A more mature approach is usually to stop and ask:
- do all of these shapes really need to be in one set?
- should these functions really be grouped together?
- could this be divided into different product directions instead?
- which brushes are strong enough to launch first, and which should be kept for later?
One of your examples shows this perfectly.
What started as a 24-brush idea was not forced into one oversized set.
Instead, it was separated into three sets, each aimed at a different scenario and a different customer pain point.
That is not just deletion.
It is a much more mature kind of product structure.
Another example works the same way.
A client wanted 12 brushes.
After detailed discussion, it became clear that some of the functions were overlapping. So in the end, the set kept a 7-piece eye-brush combination, while the larger face brushes were recommended as separate single-unit sales, with discounts if customers bought multiple pieces.
That structure had several clear advantages:
- it preserved the important shapes
- it avoided forcing everything into one set that would be heavier for the customer to buy
- it gave the customer more freedom of choice
- it lowered the purchase barrier
- it reduced the feeling of “I paid for brushes I do not really need”
Both of those cases point to the same conclusion:
the best set is not always the bigger one. Very often, it is the one with the better structure.
Sometimes reduction is the right answer.
Sometimes separation is the right answer.
Sometimes allowing some brushes to return to single-brush sales is much more reasonable than forcing them into a set.
The Best Set Is Not the One with the Most Pieces. It Is the One with the Clearest Purpose
At this point, the main conclusion of this article should already be quite clear.
On the surface, designing a makeup brush set looks like deciding which brushes to include.
But at a deeper level, what you are really deciding is:
- will the user buy it?
- will she feel it was worth it after buying it?
- can she truly use the brushes inside it?
- will she feel that every brush inside the set has a reason to be there?
So from both a product and business point of view, I always come back to this:
A good set is not the one with the most pieces, but the one with the clearest purpose.
A successful brush set is built around usage frequency, function, and market fit.
Those two ideas are enough to describe the essence of set design.
A mature set is not trying to pack in as many brushes as possible.
It is first trying to identify high-frequency needs clearly, define the budget and price band, reduce the customer’s learning burden and buying pressure, and then decide which functions must stay, which should be developed later, and which are better sold as singles.
Which means:
- a set is not better because it is more complete; it is better because it is clearer
- for a first set, high-frequency demand matters most
- shape, hair, price point, and user type need to be considered together
- a truly good set must make the customer feel it is worth buying
Once that logic is in place, the set stops being something that only “looks complete.”
It becomes something the market can actually accept as a product.
Final Thoughts
If you are defining your first makeup brush set, one of the most useful things to understand before deciding the piece count is this:
a set does not exist to look richer.
It should exist as a clearer product system—something easier to sell, easier to understand, and easier for the customer to feel was worth the money.
So instead of asking first:
Should I make a 12-piece set or a 15-piece set?
It is better to ask:
Who is this set for?
Which high-frequency functions does she really need most?
Within this budget and price band, which brushes are most worth keeping?
Once those questions are clear, the piece count, material strategy, shape choices, and overall structure all become much easier to define.
A truly good set is never good because it has more brushes.
It is good because every brush is standing in the right place.
Together, they form a complete, clear, understandable, and purchasable system.
And that is what a makeup brush set is really supposed to do.
