Hydrogel patch is one such formulation that attracts our attention. It is designed for a great advantage over the conventional cosmetics by delivering the active ingredients into skin at a desired amount and time. It is also designed for more targeted treatment and portable packaging. The hydrogel is able to hold a high amount of water when it is placed in contact with water. This action together with its occlusive effect results in the hydration of stratum corneum, leading to increase in the delivery of the active ingredient through skin. The volume of water in hydrogel also plays an important role in skin moisturizing. Moreover, it can remove dead skin cells during peel off because of its mild adhesion property.
