Name one sign that a facial treatment might be contraindicated.

A key sign that a facial treatment might be contraindicated is the presence of open sores on the skin. Open sores can indicate an ongoing skin condition or infection, which poses a risk for further irritation or introducing bacteria into the skin during treatment. Performing facial services on skin with open sores can lead to complications and worsen the condition, potentially causing severe adverse reactions.

In contrast, dry skin, acne, and oily skin can often be addressed with appropriate facial treatments. While these conditions may require specific methods or products, they do not inherently prevent the application of facials in the same way that open sores do. Thus, recognizing the presence of open sores is essential for maintaining client safety and skin health during cosmetic procedures.
