Which technique uses steam to open up pores before extraction?

The technique that utilizes steam to open up pores before extraction is steaming. Steaming is an effective method often employed in esthetics to prepare the skin for extractions. The warmth and moisture from the steam help to soften the skin and loosen the debris within the pores, making it easier to perform extractions with less trauma to the skin.

Using steam also enhances circulation and promotes relaxation, which can contribute to a more comfortable experience for clients. This preparatory step is essential for effective and safe extraction procedures, as it helps to minimize the risk of skin damage and reduces discomfort during the extraction process.

The other techniques listed do not involve the use of steam for pore preparation. Excoriation refers to the act of damaging or scraping the skin, which is not a gentle approach suitable for extractions. Hydrotherapy involves the use of water in various forms for therapeutic purposes, but does not specifically include steam as a method for preparing skin for extractions. Scrubbing involves physically exfoliating the skin but does not utilize steam to assist in opening pores.
