Why is it not advisable to apply full makeup immediately after a facial?

Applying full makeup immediately after a facial can lead to makeup that appears uneven and patchy, which is a key reason why it's advised to wait. Immediately following a facial, the skin is often highly hydrated and may still be slightly moist from the products used, such as serums and moisturizers. In this state, makeup can struggle to adhere properly, resulting in an uneven application. Additionally, the fresh, revitalized skin may have a natural glow, which can be disrupted by heavy makeup, emphasizing patches rather than providing a smooth finish. Allowing time for products to settle and the skin to stabilize enhances the effectiveness of makeup application and contributes to a more polished final look.

While other factors like skin irritation or facial oils might also pose concerns, the primary issue focuses on ensuring that the foundation and other products interact effectively with the skin's current state for even color and texture.
