The correct answer focuses on the importance of using clean tools for application, which is essential in maintaining hygiene and preventing contamination during product application. Clean tools, such as brushes, spatulas, or applicators, help ensure that products remain free from bacteria, oils, and other impurities that can compromise skin health. Using unclean tools can transfer contaminants to the skin, potentially leading to infections or adverse reactions.

Maintaining cleanliness in esthetics is critical, as clients often seek treatments for skin concerns, and contamination can exacerbate these problems. Clean tools also promote professionalism and build trust between clients and estheticians, knowing that safe practices are being followed.

While the other choices relate to product application techniques, they do not address the issue of contamination as effectively as using clean tools does. For instance, applying water or layering products in a specific order does not inherently minimize the risk of transferring bacteria or other substances from surfaces or previous applications to the client's skin. Similarly, using a spatula for extraction is a good practice, but it is only part of a larger dedication to cleanliness that ensures optimal health and safety standards.
