Basecoat & Sealer Nail Polish vs Nail Polish: which is safer?

Where these two actually differ

• We flag Heavy metals in organic pigments, Volatile organic compounds (VOCs) from solvents and Bacterial or fungal growth in water-based formula on the Piggy Paint and not on the Shellac.
• We flag UV radiation exposure from curing lamps, Photoinitiator skin sensitization, Nail plate damage and fungal infection risk and Unregulated volatile organic compounds (VOCs) and solvents on the Shellac and not on the Piggy Paint.
• The Piggy Paint is Water-based organic pigments and plant-derived resins where the Shellac is Gel-resin UV-cured polish blend (proprietary), which is most of the difference in these two grades.
• The gap is 60 points, wide enough that this is not a close call, and the Piggy Paint is the one to buy.
• We are less certain about the Shellac grade, at 45% confidence against 82%, because it discloses less.
