Which implement is specifically used to press out blackheads?

The comedone extractor is specifically designed for the purpose of removing blackheads and other types of acne. This tool typically features a small loop or scoop on one end that can be pressed against the skin to effectively extract clogged pores without causing damage to the surrounding skin. The design of the comedone extractor allows for precise application, helping to minimize the risk of scarring or infection that can occur when using fingers or other less specialized tools.

The other options, while related to skincare, do not serve the specific purpose of blackhead extraction. A facial brush may help in cleansing the skin and exfoliating, but it does not have the capability to extract comedones. A pore vacuum is an electronic device that can help to unclog pores, but it functions differently than an extractor and may not be as effective for blackheads. A blackhead remover tool might sound similar to the comedone extractor; however, this term is often used generically and can refer to various tools that might not have the same targeted design as the comedone extractor. Thus, the comedone extractor is the best choice for specifically pressing out blackheads.
