Why Polishes & Gels Thicken Over Time
Polishes and gels gradually thicken due to air exposure, evaporation of solvents, partial curing (especially gels), or inconsistent storage temperatures. Using the right thinner for the right product restores flow, shine, and performance. Using the wrong one can throw off curing, finish, or adhesion.
The Players: Which Thinner Is Which
| Product (click to shop) | Best For | What Makes It Different |
|---|---|---|
| Seche Restore | Regular lacquers / top coats (especially Seche Vite) | Formulated to restore Seche Vite’s original consistency. Pros: excellent for thickened top coats, retains shine, doesn’t dull color. Cons: not for gel polish; contains toluene, which some prefer to avoid. |
| Cre8tion Nail Polish Thinner | All types of lacquer / air-dry polishes | Acetate-based formula made to refresh regular polishes without altering shade or finish. |
| Cre8tion Gel Thinner | Gel polishes, sculpting gels (UV/LED curable) | Acetone-free; restores thickened gels while keeping cure times intact. |
| LeChat Gelos Gel Thinner | Gel systems that have started to thicken (colors, top coats, etc.) | Non-solvent gel thinner. A few drops restore original consistency without disrupting curing. |
| Kiara Sky Gel Polish Thinner | Gel polishes (UV/LED), when precise control is needed | Built-in dropper for accurate dosing, compatible with LED/UV gels. |
Ingredients & What to Watch Out For
- Solvents - Some thinners use strong solvents like toluene or butyl acetate, which work fast but have a stronger smell and can dry out skin if overused
- Match to the product – Regular polish and gel polish are made differently. Using a regular thinner in gel polish can mess up the curing process and leave a sticky finish.
- Solvent vs. non-solvent – Solvent thinners are best for regular polish. Non-solvent thinners are specially made for gels and won’t interfere with curing.
- Safety - Always work in a well-ventilated area, cap tightly after use, and store away from heat or sunlight.
“Which One to Use When” & What We Recommend
- Thickened regular nail polish / lacquer → Seche Restore (for Seche Vite) or Cre8tion Nail Polish Thinner
- Thickened gel polish colors or top coats (LED/UV) → Cre8tion Gel Thinner or Kiara Sky Gel Polish Thinner; these maintain cure times and finish.
- Builder gels or sculpting gels that have become too viscous → LeChat Gelos (non-solvent).
How to Safely Thin Polishes & Gels
- Wipe bottle neck and cap for a tight seal.
- Shake thinner bottle gently before use.
- Add one drop to the product bottle. Always add small increments (1–2 drops).
- Close, roll between palms (avoid shaking vigorously).
- Rest for a few minutes. Test.
- For gels: swatch and cure to confirm proper curing.
- Store upright, tightly sealed, and away from heat/light.
