Gel Polish vs GELement: which is safer?
Opi GELement is the clear pick. Gelish Gel Polish carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Acrylate monomer sensitization and contact irritation, Incomplete curing and sticky layer residue, Occupational inhalation exposure in salon environments and Pigment and colorant identity opaque on the Gelish and not on the OPI.
- We flag UV/LED light exposure (cumulative), Unreacted acrylate monomers (contact sensitization), Respiratory irritation from uncured vapors during application and Nail plate thinning and brittleness (physical damage from removal) on the OPI and not on the Gelish.
- The Gelish is gel polymer resin (acrylate-based coating) where the OPI is gel polish (acrylates, oligomers, resins), which is most of the difference in these two grades.
- The gap is 35 points, wide enough that this is not a close call, and the OPI is the one to buy.
- We are less certain about the Gelish grade, at 35% confidence against 72%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
