The use of disposable applicators, such as cotton swabs, sponges, and spatulas, ensures that products are applied hygienically, with a fresh applicator used for each client and each dip into product containers. This practice helps prevent contamination of products and reduces the risk of spreading bacteria or viruses between clients. Disposable applicators are immediately discarded after use, maintaining a high level of hygiene and safety during all treatments, especially those involving sensitive areas like the face or eyes.
