What is a key difference between stainless steel tweezers and titanium tweezers?

The correct answer highlights a significant aspect of material properties regarding allergic reactions. Stainless steel, while commonly used and effective for a variety of tools, may contain nickel, which is a metal known to cause allergic reactions in some individuals. This can lead to skin irritation or sensitivity when stainless steel tweezers come into contact with the skin, especially during beauty treatments involving lashes and brows.

In contrast, titanium is known for being hypoallergenic and less likely to cause such reactions, making it a preferred choice for medical and personal care tools. This is particularly important in beauty applications where the risk of irritation needs to be minimized.

Understanding this difference is critical for professionals in the beauty industry, as they want to ensure the safety and comfort of their clients. The other options present alternative characteristics of the two materials but do not address the significant health consideration related to allergic reactions.
