NSF Contents and Claims Certified
More than skin deep
NSF Contents and Claims Certified ensures beauty and personal care products are accurately labeled, with ingredient claims independently verified for truth and accuracy. Through independent, science-based evaluation of the finished product, NSF assesses ingredient content, reviews safety considerations, evaluates content claims for accuracy and conducts ongoing oversight to help ensure products continue meeting certification requirements over time.
Your serum is transparent.
Make sure your label is too.
Terms like “clean,” “safe,” and “nontoxic” aren’t always defined or verified. NSF Contents and Claims Certification replaces ambiguity with independent evaluation and documented evidence so consumers have a clear, objective basis for trust.
If it’s on the label, it’s backed by evidence
In personal care, what matters is how a formula performs. NSF certification evaluates products are what they say they are, ingredient claims are supported, and safety risks are assessed.
3rd party certified
NSF has no financial stake in whether a product passes or fails. Certification is conducted by our experts, not self-reported by brands - removing any conflict of interest from the process.
Beyond the ingredient list
NSF assesses the finished product as it's actually used including how ingredients interact, manufacturing conditions, and real-world performance factors.
Confidence that doesn’t expire
Certification includes continued review and periodic retesting to ensure products stay compliant over time, not just at the point of approval.
