Over the last few years, the nail industry has become obsessed with speed and convenience. “All-in-one” systems promise everything in a single bottle — base coat, builder and sometimes even top coat combined together.
At first this may sound absolutely ideal - fever steps, Faster appointments, easier application, less complexity and less expenses
But when we look beyond marketing and actually examine the chemistry behind professional nail systems, a very different picture appears.
The reality and my personal believe as a brand owner is that properly designed multi-step systems remain significantly more reliable, more stable and often safer than most all-in-one products.
And there is a scientific reason for that. Lets look into that more and in details...
Different Layers Exist for a Reason !
Traditional gel systems were never separated into: base coat, builder gel and top coat just to make services longer or more complicated.
Each layer was originally developed to perform a completely different chemical function. Trying to force all of those functions into "one bottle" creates unavoidable compromises.
Base Coats Are Designed for Adhesion — Not Structure
A professional base coat is specifically engineered to bond to the natural nail plate. The ingredients and levels of certain chemicals are completely different to ones used in structural builder gels.
To achieve this, formulas often contain:
-
highly adhesive monomers,
-
flexible oligomers,
-
penetration-promoting ingredients,
-
and adhesion enhancers as phosphates etc...
These ingredients help create excellent retention and flexibility.
However, they are generally intended to be applied in very thin layers.
Why? Because many adhesion-focused ingredients are not ideal for thick structural applications. When these types of ingredients are used excessively in thicker layers, they may: create uneven curing, increase heat spikes, leave higher levels of residual uncured monomers, reduce structural rigidity, and increase long-term instability.
This is one of the key reasons professional systems separate the adhesion layer from the structural layer.
Builder Gels Require Completely Different Chemistry
Builder gels have a very different purpose.
They must: support structure, maintain an apex, resist impact, remain durable over weeks of wear, while still flexing slightly with the natural nail, they should be able to create thicker layers without causing damage to the natural nail
Achieving this balance requires a carefully controlled polymer network.
A builder gel optimized for strength should not behave chemically like a base coat. Builder gels often contains more photoinitiators to promote proper curing of thicker layers applied.
Yet many all-in-one systems attempt to combine both functions into a single formula. This forces chemists into compromise formulations that are rarely as optimized as dedicated separate products.
When it comes to top coat the chemistry behind it and ingredients inside are even more different to ones used in base and builder.
The “All-In-One” Concept Sounds Better Than It Performs
From a marketing perspective, all-in-one products are brilliant.
From a formulation perspective, they are extremely difficult to perfect these kind of products.
One bottle is expected to:
-
adhere like a base,
-
build strength like a builder,
-
self-level perfectly,
-
resist cracking,
-
maintain flexibility,
-
cure evenly on surface and inside,
-
minimize heat,
-
and sometimes even provide top coat durability.
These requirements often directly conflict with each other chemically.
As a result, many all-in-one systems become overly soft, overly flexible, nconsistent during curing, or structurally weaker than proper multi-step systems.
using certain adherence promoting chemicals used in base coats in thick layers (for example in builder gels) may affect the proper function of certain photoiniciators which may lead to undercuring issues and that's why
Polymerization Is One of the Biggest Concerns
One of the most important — and least discussed — issues in the nail industry is polymerization quality. A gel may appear fully cured on the surface while remaining partially uncured internally.
This becomes more problematic when products are applied thickly, formulas are heavily pigmented, or one formula is overloaded with multiple performance demands like "all-in-one".
Multi-step systems where we use separate Base coat, builder and Top coat, like Nail Jam, are generally easier to optimize because each layer has a narrower, more controlled role.
This allows more predictable curing and more stable crosslinking leading to complete polymerization.
More Convenience Often Means More Compromise
The modern nail industry increasingly rewards speed, simplicity and viral trends.
But chemistry does not care about marketing. A product cannot magically become: ultra-flexible, ultra-hard, ultra-adhesive, low-heat, perfectly self-leveling and perfectly curing without compromise somewhere in the formula. Many all-in-one systems achieve convenience by sacrificing long-term structural performance or curing stability.
This is why experienced nail technicians may experience ncreased lifting, softness, peeling, heat spikes,or reduced retention
One of the greatest advantages of multi-step systems is control.
Professional nail technicians can customize:
-
adhesion - use prescriptive base coat for every client needs
-
flexibility - choosing the right viscosity of Hard or soft gel to meet clients needs
-
structure - whenever clients needs just soft light overlays or strong builder customised to their lifestyle
-
and finish
For example:
-
weaker nails may need a more flexible base,
-
long extensions may require a stronger builder,
-
certain clients may benefit from harder/thicker top coats.
A single all-in-one product simply cannot offer the same level of customization.
Safety in nail chemistry is not determined by trends like:
-
“one-step,”
-
or “builder in a bottle.”
The most important factors are:
-
complete polymerization,
-
stable formulation,
-
reduced skin exposure,
-
predictable curing,
-
and controlled application.
Multi-step systems generally allow greater formulation precision and more predictable curing behavior, which is one reason many professional brands still rely on them despite the popularity of simplified systems.
Why Many High-End Professional Brands Still Use Multi-Step Systems
There is a reason why many respected professional brands continue using separate base coats, separate builders and separate top coats.
Not because they are outdated.
But because separating functions creates:
-
better chemical stability,
-
more predictable performance,
-
stronger structural integrity,
-
improved retention,
-
and more reliable long-term wear.
In professional nail chemistry, specialization almost always performs better than trying to make one product do everything.
Convenience has become one of the biggest selling points in the modern nail industry. But faster does not automatically mean better.
At Nail Jam , this philosophy is at the core of our product development. Different clients, nail types and application styles require different levels of adhesion, flexibility and strength — which is why we believe one single formula cannot perfectly suit every situation.
That is also the reason we introduced our prescriptive base coat system, designed to allow nail professionals to mix and match products depending on the individual client’s needs. Instead of forcing one formula to perform every function, our system gives nail technicians greater control over retention, flexibility and structure by pairing different base systems with different builder gels.
And in my opinion, truly professional results come from systems specifically designed to work together, not from asking one product to do everything at once.
