Best practice
When describing trends, use "reduces over time" to clearly indicate a diminishing quantity or effect as time progresses. This is particularly useful in scientific and business contexts where precise language is necessary.
Common error
Avoid using "reduces over time" when you simply mean something has been reduced once. "Reduces over time" implies a continuous or gradual decrease, not a one-time event. For a single reduction, say "was reduced" or "has been reduced".
