What should be done with creams and semi-solid substances before usage?

The correct approach for handling creams and semi-solid substances emphasizes the importance of sanitation and hygiene. Using a sanitized spatula to remove these products helps prevent contamination that could occur from using fingers. Fingers can introduce bacteria and other pathogens into the product, which can compromise its integrity and potentially harm the skin or health of the individual using it. Therefore, utilizing a sanitized spatula ensures that the product remains uncontaminated and safe for use.

In contrast, applying creams directly with fingers can lead to cross-contamination, especially if the fingers are not clean. Mixing these products with others without knowledge of their compatibility could affect their efficacy or cause adverse reactions. Warming the products may be beneficial in some contexts, but it does not address the sanitation concerns necessary for safe application. Thus, removing them with a sanitized spatula is the most responsible practice.
