Which practice reduces the risk of allergic reactions during treatments?

Performing patch tests before treatments is crucial in reducing the risk of allergic reactions. A patch test involves applying a small amount of the product to a discreet area of the skin, allowing the esthetician to monitor for any adverse reactions. This practice helps to identify potential allergens in the products being used, as individuals may have varying sensitivities to different ingredients. By determining a client’s specific reactions prior to a full application, estheticians can tailor treatments more safely and effectively.

The other practices mentioned can actually increase the risk of using products that cause allergic reactions. Using a variety of strong fragrances may overwhelm the senses and heighten the chance of sensitivities. Encouraging clients to self-diagnose can lead to misidentification of allergies, as they may not possess the knowledge or expertise to assess their own skin reactions accurately. Lastly, using expired products introduces higher risks, as ingredients may break down over time and become irritating or even harmful to the skin. Thus, patch testing stands out as a proactive step in ensuring client safety during treatments.
