The use of an antiseptic solution is specifically intended to prevent bacterial growth on the skin. Antiseptics contain active ingredients that inhibit the growth of microorganisms, making them effective for cleansing and disinfecting areas of the skin to reduce the risk of infection. This is particularly important in a cosmetology setting where maintaining skin cleanliness is crucial for the health and safety of clients.

In contrast, a moisturizer is designed primarily to hydrate and soften the skin, without any antibacterial properties. Sunscreen serves to protect the skin from harmful UV rays, which can lead to sunburn and skin damage but does not address bacterial growth. An exfoliant is used to remove dead skin cells, improving the skin’s texture and appearance but does not have antibacterial properties either. Thus, the essential role of an antiseptic solution in inhibiting bacterial growth clearly highlights why it is the correct choice in this context.
