Barrier cream is designed to protect the skin from irritants and contaminants, and for it to remain effective, it needs to be reapplied regularly throughout the day. This is because barrier creams can wear off due to various factors such as washing hands, sweating, or physical activities that may remove or degrade the cream's protective layer. Regular application ensures that the skin remains shielded from potential hazards, maintaining its integrity and minimizing the risk of skin irritation or breakdown.

The effectiveness of barrier creams is contingent on their consistent presence on the skin, particularly in environments where the skin is exposed to hazardous substances or abrasive conditions. Therefore, regular reapplication is crucial to uphold the protective benefits that these creams provide, emphasizing the importance of maintaining skin protection over the course of the day, rather than just at the start or end of a shift or during specific times.
