Leafgel Color Gel K02 Jelly Fuchsia [See-through Series]
Lower concern; typical cosmetic gel with no known PFAS triggers, but no brand transparency on formulation.
Leafgel Color Gel K02 is a cosmetic nail/beauty gel product. Standard gel cosmetics do not typically contain intentional PFAS, and this product shows no red flags like water-resistance claims, nonstick coatings, or grease-resistant treatments.

The full breakdown
What it's made of and why it matters
Leafgel K02 is a UV-cured gel polymer (likely acrylic-based cross-linked resin) formulated as a color gel in the 'jelly' series, meaning it has lower pigment density and higher translucency. Gel polishes cure under UV or LED light and remain flexible once set, reducing chipping compared to traditional lacquer. The 'see-through' formulation suggests minimal heavy pigment load, which generally correlates with lower heavy-metal colorant burden, though no independent analysis of this specific shade is publicly available.
The brand's record and disclosure
Leafgel is a South Korean cosmetics brand with moderate presence in global nail markets, but publicly available ingredient disclosure and safety certifications are limited. The brand has not published detailed formulation statements or responded to common cosmetic transparency inquiries in documented public records. No major recalls or health incidents are on record for this product line, and it does not advertise vegan, cruelty-free, or non-toxic positioning that would signal third-party audit claims.
How it compares in its category
Gel polishes as a category carry lower reformulation risk than traditional liquid lacquers because the polymer matrix is cross-linked under UV, reducing volatile organic compound (VOC) emissions during use. Jelly gels typically contain fewer synthetic iron oxides and organic dyes than opaque shades, positioning them lower-risk for heavy-metal pigment accumulation. Leafgel's pricing and market positioning sit in the mid-tier bracket, neither premium (with third-party testing claims) nor ultra-budget (where unlabeled fillers and impurities are more common).
If you buy it
Ensure good ventilation during application and removal to minimize inhalation of any volatile compounds during curing. Avoid prolonged skin contact with uncured gel; wash hands immediately after application and use a barrier (like cuticle oil) on skin before painting. Remove gel only with acetone-soaked wraps or professional removal to avoid unnecessary solvent exposure; peel-off removal can damage nail beds. Replace the product if the consistency becomes watery, discolored, or separates, as gel polymers can degrade or harbor bacterial growth if stored above 25C or left open.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Heavy metals in synthetic pigments (colorants)
Jelly gels typically use lower pigment loads and fewer synthetic iron oxides than opaque shades. No recalls or test data for this specific Leafgel product are publicly documented, so residual heavy-metal risk is not established.
Volatile organic compounds (VOCs) during curing
Gel polishes emit low-level VOCs during UV or LED curing; the cross-linked polymer matrix limits post-cure off-gassing compared to traditional lacquers. Exact VOC profile for Leafgel K02 is not disclosed, so exposure depends on application ventilation and curing time.
Skin sensitization from uncured polymer or residual monomers
Uncured gel can cause contact dermatitis or allergic sensitization in sensitive individuals; nail technicians and frequent users face higher cumulative risk. Leafgel does not publish monomer or allergen disclosure, so individual risk profiles cannot be assessed without patch testing.
Bacterial or fungal growth in gel reservoir if stored improperly
Gel polishes are water-resistant but can trap moisture or degraded polymer matter if caps are left loose or product is exposed to temperature fluctuation. No preservative-system data is publicly available for Leafgel K02, so contamination risk depends on user storage practices.
Acetone solvent exposure during removal
Gel removal via acetone-soaked wraps is the standard method and carries well-documented acute and chronic solvent-exposure risks (drying, irritation, systemic absorption). This hazard is inherent to gel-polish category, not specific to Leafgel, but should inform removal frequency and technique.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
