What product may be used to stop minor bleeding on a client?

The appropriate product to stop minor bleeding on a client is powdered alum. Alum, which is an astringent, has properties that contract tissues and promote coagulation, making it effective for controlling bleeding from minor cuts or abrasions. Its use in esthetic practices can be particularly beneficial when performing procedures that may inadvertently break the skin, as it helps to quickly minimize blood loss.

While alcohol wipes are useful for disinfecting the skin prior to a procedure, they do not aid in stopping bleeding and can actually cause further irritation to a fresh wound. Cotton balls are primarily used for absorption or application of products but do not have any hemostatic properties and would not stop bleeding on their own. Corticosteroids are anti-inflammatory medications and are not designed for use in stopping bleeding; their purpose is more aligned with reducing inflammation and allergic reactions in the skin, making them unsuitable for this specific purpose.
