Self-Leveling Gel

What leveling actually is

A gel that levels has been formulated with a lower viscosity and a longer working time, so it behaves briefly like a liquid rather than a paste. Left alone for a few seconds it finds its own flat surface. A thicker, non-leveling gel holds whatever shape the brush left, which is why brush strokes and ridges survive into the cure. Neither is better; they are two different handling characteristics, and knowing which is in the bottle tells you how to apply it.

• Give it a few seconds. Fussing with the brush after the coat is down fights the property you paid for.
• Brush strokes vanish on their own. If they are still there, the gel was not a leveling formula or the coat was too thin.
• It flows toward the lowest point. Which is the whole of the good news and the whole of the bad news.
• Curing is not drying. The property behind every one of these behaviors is set out on the gel polish collection page.

Why gel polish peels at the edges

This is the most common problem with the format and it is almost always the same cause. Gel that flows will flow onto the cuticle and into the sidewalls if there is too much of it, and any gel touching skin has nothing to bond to. Skin moves and sheds, so that edge becomes a lift point within days, and once one edge lifts the whole coat starts peeling from there. The color is not at fault and neither is the lamp.

• Leave a visible margin. A hairline of bare nail at the cuticle is the single most effective fix.
• Less product, not a lighter touch. Flooding comes from volume on the brush rather than from pressure.
• Cap the free edge. Running the brush along the tip seals the layer where wear starts.
• Check the sidewalls too. Gel pooling against the skin at the sides lifts for exactly the same reason.
• Preparation decides adhesion. What happens before any color goes on is covered on the nail care page.

Why it stays soft or does not cure

A leveling gel looks smooth at any thickness, which quietly encourages heavy coats. Light has to reach all the way through a layer to cure it, and a thick coat cures at the surface while the material underneath stays soft. The result is a finish that dents under a fingernail, wrinkles when pressed, or peels away in one sheet a day later. Two thin coats cure completely where one thick coat never will.

• Thin coats, twice. This is the answer to almost every cure complaint with a leveling formula.
• A smooth surface hides depth. Because it self-levels, you cannot judge thickness by looking at it.
• Wrinkling means undercured. A surface that creases has cured on top of something still liquid.
• Pigment load matters. Dense colors block more light, so a high pigment gel needs thinner coats than a sheer one.

The sticky layer is two different things

Almost every gel leaves a tacky film after curing, and most of the time that is entirely normal. Oxygen at the surface interferes with the reaction, leaving a thin uncured layer that wipes away with alcohol and is meant to. What is not normal is stickiness that persists after wiping, or softness that goes deeper than the film. That is undercure, and the cause is thickness or lamp time rather than the product.

• A thin tacky film is expected. It wipes off cleanly and the finish underneath is hard.
• Still soft after wiping is not. That is uncured gel, and it means going back to thinner coats.
• Some formulas leave none at all. A no-wipe top coat is formulated to cure through completely.
