How it's used

This idiom is frequently used in professional or medical contexts to manage expectations when a solution does not yield uniform results. It serves as a polite way to explain why a recommendation might fail for some people despite working for others. While it sounds slightly formal, it is perfectly acceptable in everyday conversation when discussing health, beauty, or lifestyle advice.
