Which factor should be prioritized when applying makeup to ensure the best results?

Prioritizing the factor of ensuring the client's skin is not lifted during makeup application is essential for achieving the best results. This aspect is vital because lifting the skin can cause discomfort, lead to uneven makeup application, and ultimately detract from the client's overall appearance. Proper technique in makeup application emphasizes the importance of respecting and caring for the skin's integrity.

When the skin is handled gently and appropriately, it allows for smoother application, better blending, and a more polished final look. Furthermore, maintaining the skin's condition minimizes the risk of irritation and ensures that makeup adheres properly, providing lasting coverage.

In contrast, focusing on the cost of products, speed of application, or using only natural products does not guarantee the best outcome. While these factors may have their merits, they do not directly relate to the quality of application or the well-being of the client's skin during the process. Thus, a skillful and careful approach to skin handling takes precedence for optimal makeup results.
