How does a steamer benefit the skin during a facial?

The steamer provides significant benefits to the skin during a facial primarily by opening the pores and aiding in hydration. The warm, moist air generated by the steamer helps to soften the skin and loosen debris, such as dirt, oil, and makeup residue. This process prepares the skin for deeper cleansing and allows for more effective extraction of impurities. When the pores are opened, it also facilitates the absorption of products applied afterward, enhancing the overall hydration of the skin.

The other options present valuable effects but do not align with the primary function of a steamer during a facial. For example, while a steamer can contribute to an overall refreshing experience, it does not have a cooling effect suitable for sunburned skin. Exfoliation is typically achieved through physical or chemical means rather than steaming, and while steaming can improve circulation and give the skin a healthy glow, the direct enhancement of vibrancy is more closely linked to other factors, such as the products used and skin health. Therefore, the primary benefit of using a steamer is its ability to open the pores and hydrate the skin, making option B the most accurate choice.
