Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want a clean polish from a widely available mainstream brand that publishes a checkable ingredient list
You specifically want to avoid benzophenone UV filters, since this formula contains none
You want color you can paint and wear in minutes without a UV or LED lamp
You are happy with about a week of wear from a natural-origin lacquer at a normal price
You want a widely available polish that verifiably excludes the toxic trio, TPHP and parabens
You want long, gel-like wear up to 11 days without buying a UV or LED lamp
You value a brand that publishes its full ingredient list so claims can be checked
You are comfortable with a benzophenone UV filter in exchange for proven wear at a mainstream price
The main thing to know
This is a regular nail polish, not a long-wear system. OPI puts chip-free wear at about a week, so if you need color that survives two weeks of daily wear, a gel is the better choice.
The published ingredient list contains Benzophenone-1, an estrogenic UV filter, even though OPI markets a 9-free formula. It is the one hazard left in an otherwise well-vetted polish, and it sits outside the named 9-free claim.
Skip this if you...
You need two-plus weeks of chip-free wear and are willing to use a gel and lamp system to get it
You require a fully vegan formula, since OPI states Nature Strong is not 100% vegan
You want a tested, third-party wear figure rather than the brand's own week estimate
You are specifically avoiding benzophenone or oxybenzone UV filters for hormone reasons
You want every ingredient covered by the free-from claim, not just the nine named substances
You prefer a salon gel manicure and do not mind the lamp and removal that come with it
Neither of these quite what you're looking for?

Not necessarily. The overall score reflects how we weight those three pillars, but your priorities may differ. If you care most about safety, compare the safety scores directly.
