The cosmetic industry is evolving with the advent of 3D printing, allowing personalization of skincare products. This study investigated how different print design settings affect the hydration performance of hydrogel-based masks. Using an extrusion-based 3D printer, 3-layered gelatin hydrogel occlusive and porous patches were printed and applied on healthy volunteers under no-occlusion (4h) and occlusion (24h; plastic occlusion stress test).
Results revealed occlusive patches enhanced moisture by 108.85%, in contrast to a 45.38% increase from porous patches. Additionally, the occlusive design showed greater variation in transepidermal water loss, while the porous variant reduced it by -9.96% after 4h. Porous patches also retained more skin surface water. Overall, mask geometry influences hydration, correlating with the skin occlusion degree determined by design.

The cosmetic industry is currently witnessing a surge in the personalized skincare trend, providing an alternative to the conventional one-size- and one-treatment-fits-all skincare approaches  (1, 2). The concept of personalized beauty has been further revolutionized by exploring 3D printing technologies, which enables the creation of customized skincare products that cater to individual skin requirements and characteristics. In addition, 3D printing offers flexibility in adjusting bioactive dosages and release rates and allows printing different designs and geometries, making modifications to skincare products fast and efficient (2–5).
Indeed, 3D printing technologies are making inroads into several skincare areas, including the development of customized cleansers, makeup products, personalized packaging, and customized hydrogel-based facial masks (6). Focusing on hydrogel-based facial masks, which are one of the most popular mask types for sensitive skins due to its cooling and soothing effects (7), major advances have been made in terms of customizing this kind of skincare products.
