Antiseptics are chemical germicides specifically designed for use on the skin. They are formulated to reduce the risk of infection by killing or inhibiting the growth of microorganisms without harming the skin. Common examples of antiseptics include alcohol, iodine solutions, and hydrogen peroxide, which can be safely applied to skin surfaces.

In contrast, bleach is a strong chemical compound primarily used for disinfecting surfaces and laundry; it is not suitable for direct application on skin due to its harshness and potential for causing irritation or burns. Disinfectants, while effective at eliminating germs on inanimate objects, are not intended for use on living tissues, making them inappropriate for application to the skin. Quat solutions, or quaternary ammonium compounds, are typically used to clean salons and surfaces but are not formulated for skin application and may cause irritation.

By understanding these distinctions, it becomes clear that antiseptics play a vital role in skin care, particularly in maintaining hygiene and preventing infection in cosmetology and nail technology practices.
