Which of the following can be used for skin protection against lasers?

Using sunscreen creams approved by ANSI is an effective method for skin protection against lasers because these products are specifically designed to provide a barrier against harmful ultraviolet (UV) and other radiation types, including laser light. The American National Standards Institute (ANSI) has established safety standards that these sunscreens must meet to ensure they offer reliable protection. This implies that they have been evaluated for their effectiveness in minimizing skin damage caused by specific radiation scenarios, including lasers, making them a recommended choice for protecting exposed skin during laser procedures.

While sunblock with SPF 15 can provide some level of skin protection against UV rays from the sun, it does not specifically account for the different wavelengths and intensities of laser light, making it less suitable for laser applications. Loose-fitting garments can offer a physical barrier against laser exposure, but their effectiveness heavily depends on the material and weave of the fabric. Similarly, while polyester clothing may provide some level of protection due to its density and reflective properties, it does not have the same targeted protection features as ANSI-approved creams, making it a less reliable option for laser safety.
