Poor-Quality Gel Polish: How to Recognize Inferior Products

Gel polishes are among the most popular products in modern nail care. They offer long-lasting color, shine, and durability. But not all products on the market meet professional standards. Low-quality gel polishes can lead to disappointing results and, worse, may cause long-term damage to the natural nails. At MONLIS School in Munich, one of the top institutions for manicure and pedicure training in Bavaria, students learn from day one how to recognize and avoid inferior products – a crucial skill for every nail technician.

Why is gel polish quality so important?

A high-quality gel polish not only creates a flawless look but also protects and strengthens the natural nail while providing a smooth, even, and long-lasting finish. In contrast, poor-quality products can:

• dry out or discolor the nail plate,

• cause allergic reactions or skin irritation,

• apply unevenly and bubble,

• chip or peel within days.

Using inferior materials compromises not only the client’s satisfaction but also the long-term reputation of the salon or nail technician.

Signs of poor-quality gel polish

1. Strong, harsh chemical smell:
Premium gel polishes typically have a mild, almost neutral scent. A strong, unpleasant chemical odor may indicate the presence of cheap or harmful ingredients or poor manufacturing practices.

2. Too runny or too thick consistency:
A good gel polish has a creamy, balanced texture that spreads easily. If it’s too runny, it can flood the cuticles and be difficult to control. If it’s too thick, it may clump or form streaks and bubbles during application.

3. Color changes or patchiness when curing:
If the polish changes color significantly or develops uneven patches under a UV/LED lamp, it likely contains unstable or low-grade components. High-quality gel polish cures evenly and retains its true color.

4. Weak color payoff even after multiple layers:
If two or three coats still don’t provide solid coverage, this is a sign of poor pigmentation or formula quality. Professional products usually deliver strong color results even with one layer.

5. Short wear time and early chipping:
A well-formulated gel polish should last 2–3 weeks without major issues. If it begins chipping, cracking, or peeling within a few days, it likely contains cheap binders or has an imbalanced composition.

6. Skin irritation or allergic reactions:
High-quality gel polishes are dermatologically tested and free of harsh substances like formaldehyde, toluene, or DBP (dibutyl phthalate). If a client experiences itching, redness, or irritation, it's a red flag – the product may not be safe.

What should the label tell you?

Another important factor is clear labeling. A reputable gel polish will always display:

• a full list of ingredients,

• expiration date,

• manufacturer details,

• clear usage instructions.

If this information is missing, especially with low-cost online purchases, it’s best to avoid using the product. Certified and regulated suppliers are the safest choice.
