What does hand washing primarily help to prevent?

1. Allergic reactions

2. Skin irritation

3. Spread of germs

4. Infection on tools

The correct answer is: Spread of germs

Hand washing primarily helps to prevent the spread of germs. This practice is vital in both personal hygiene and in professional settings such as esthetics, where maintaining a clean and safe environment is crucial for client safety. By effectively washing hands, you remove dirt, bacteria, and viruses that can easily transfer to clients or the instruments used during treatments. While allergic reactions and skin irritation are important considerations in skincare, hand washing does not directly address these issues. Allergic reactions are often related to product ingredients rather than the presence of germs, and skin irritation can result from various factors, including product use or environmental conditions. Infection on tools is a concern as well; however, while hand washing contributes to overall sanitation, it alone does not prevent infections related to unsterilized tools unless the tools are properly disinfected or sterilized. Therefore, the primary function of hand washing in this context is to prevent the transmission of harmful microorganisms.
