Hardwear Shine UV Topcoat vs Cosmetics Mac Nail Lacquer Polish Over-Accessorized (Pink Gold Glitter ) Boxed: which is safer?

Where these two actually differ

• We flag Uncured resin monomers (sensitization/irritation), Photoinitiators and UV sensitivity, Fragrance allergens and Volatile organic compounds (VOC) off-gassing on the Butter London and not on the MAC.
• We flag Volatile organic compounds (VOCs) and solvent inhalation, Phthalate plasticizers, Heavy metals in synthetic pigments and mica and Formaldehyde-releaser resins on the MAC and not on the Butter London.
• The Butter London is UV-curable gel topcoat, formula not publicly disclosed where the MAC is nitrocellulose, plasticizers, pigments, 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 MAC is the one to buy.
• We are less certain about the Butter London grade, at 35% confidence against 72%, because it discloses less.
