What is the consequence of using expired products on clients?

  1. Risk of irritation and ineffective results

  2. Increased longevity of the product

  3. No known consequences

  4. Enhanced effectiveness

The correct answer is: Risk of irritation and ineffective results

Using expired products on clients poses a significant risk, primarily because these products can lead to irritation of the skin or hair. Ingredients in cosmetics and skincare items can degrade over time, leading to changes in pH levels and a breakdown of active components, which may result in adverse reactions. Additionally, expired products are often less effective due to the diminished potency of their active ingredients. This means that clients may not experience the desired outcomes, leading to dissatisfaction and potential harm. Therefore, maintaining awareness of product expiration dates is crucial for ensuring both safety and quality in any cosmetology practice.
