Which method increases product penetration during treatments?

Using steam during treatments is effective for increasing product penetration because it opens up the pores of the skin through the application of heat and moisture. When the skin is heated, the outer layer becomes more permeable, allowing active ingredients in products to penetrate deeper layers of the skin. This enhanced absorption can lead to improved efficacy of the skincare products being used, making steam a commonly employed technique in various facials and esthetic procedures.

Additionally, while applying with fingers and massaging the product can aid in spreading and lightly working the product into the skin, they do not create the same level of pore opening or moisture infusion as steam does. Using cold compresses, conversely, tends to constrict blood vessels and pores, which would limit product absorption rather than enhance it. Therefore, the method that most significantly boosts penetration is steam application.
