Understanding Gel Types and Their Differences

To make it easy to understand why different products are used in professional nail services, all modern gel materials are divided into 4 primary groups based on their strength and flexibility.

Soft Gels (Flexible Gel Systems)

The most flexible products in the nail industry. Once cured, they remain supple and adapt naturally to the movement of the nail plate, acting as a shock-absorbing layer.

 What it includes: Classic base coats, rubber bases, and gel polish colors.

 Consistency: Ranges from thin and fluid (classic base) to thick and viscous (rubber base).

 How it works:

 Classic Base Coat: Acts like double-sided tape—creates adhesion between the natural nail and gel polish without adding volume or shape.

 Rubber Base: Not only ensures strong adhesion but also evens out the nail plate. Formulated with rubber components, it absorbs everyday impacts while flexing alongside the nail.

The “golden middle”—a modern gel category that bridges the gap between base coat elasticity and hard gel strength.

 What it includes: Builder In A Bottle (BIAB), liquid builder gels and soft builder gels.

 Consistency: Medium-viscosity, self-leveling gel.

 How it works: Provides structural strength, builds correct apex architecture, and allows for minor free-edge extensions. It is noticeably firmer than a base coat while maintaining partial flexibility to protect the nail from snapping at the stress area.

The firmest, most rigid category of gel enhancements, offering maximum mechanical resistance with zero flexibility after UV/LED curing.

 What it includes: Traditional builder gels in jars/pots, sculpting gels and hard gels.

 Consistency: Ranges from fluid self-leveling formulas to thick jelly textures.

 How it works: Withstands heavy mechanical stress without bending. Designed for sculptured extensions on paper forms, extreme shapes, and reconstructing curved, hooked, or severely damaged nails.

A distinct, innovative hybrid category engineered by combining the durability of acrylic with the flexibility and workability of gel.

 What it includes: Traditional polygel/acrygel in tubes or jars and liquid polygel.

 Consistency: In tubes and jars—very thick, completely non-drip, and never runs into the cuticles; in bottles with a brush—more fluid and evenly self-leveling.

 How it works: Cures only under a lamp, allowing unlimited working time for precision sculpting, repairing broken sidewalls/corners, creating durable extensions, or shaping architecture with Dual Forms.

Comparing Gel Systems and Traditional Acrylic

Both materials belong to the same polymer (acrylate) family—a safe medical-grade plastic widely used not only in the nail industry, but also in dentistry (such as dental fillings). The main difference lies in their structure and how they wear on the natural nail

Structural Flexibility & Impact Protection

Both acrylic and gel can break or crack under heavy impact. However, because traditional acrylic is extremely rigid, it often snaps violently along the stress line, pulling natural nail layers with it. Gel systems provide balanced structural flexibility that absorbs everyday shock better, helping minimize severe trauma to the natural nail if an accident happens.

 
 
 

Traditional acrylic requires a liquid monomer that releases strong, noticeable airborne fumes as it evaporates. Gel cures exclusively under gentle LED/UV light and emits no harsh chemical vapors, making the service peaceful, clean, and completely comfortable for your senses.

 

 

Nail damage is rarely caused by enhancements themselves—it happens through over-filing during prep and removal. Traditional acrylic often requires heavier surface etching and extensive filing during removal, which can wear down the natural nail plate over time. Gel systems require only minimal, gentle surface prep for optimal adhesion, minimizing thinning.
