Which of the following practices can enhance product absorption in a skincare routine?

Exfoliation is a key practice that can significantly enhance product absorption in a skincare routine. By removing dead skin cells and debris from the surface of the skin, exfoliation allows subsequent skincare products—such as serums, moisturizers, and treatments—to penetrate more effectively. This improved penetration can lead to better efficacy of active ingredients, making them more beneficial for the skin.

Integrating exfoliation into a regular skincare regimen ensures that the skin remains fresh and receptive to the products applied afterward. It's important to choose the right type of exfoliation, whether physical or chemical, to suit one's skin type and concerns, to maintain a healthy balance and avoid irritation.

In contrast, using hot water to wash the face can strip the skin of its natural oils, potentially leading to dryness and irritation, which can impede the effectiveness of skincare products. Additionally, using oil-based products first can create a barrier that makes it harder for water-based products to be absorbed. Skipping moisturizer altogether can also leave the skin dehydrated and less capable of absorbing other products. Thus, exfoliation stands out as the ideal choice for enhancing product absorption in a skincare routine.
