The product information mentions hyaluronic acid, collagen, vitamin C, calendula, and retinol. What is the primary purpose of each in the context of these eye patches? — Gift set "5 Senses" consisting of five 8 g hydrogel eye patches, DIZAO.

Each active contributes to the overall experience and effect of the patches, based on their widely recognized cosmetic properties. Hyaluronic acid is a humectant, meaning it helps bind and retain water on the skin's surface, which can make the under-eye area look smoother and less dry. Collagen is valued mainly for its film-forming effect; it helps create a temporary, supple layer on the skin, improving the feel and soft appearance after use. Vitamin C (often as a derivative like ascorbyl glucoside in such formats) is a common brightening ingredient that can help improve the look of tired skin and uneven tone. Calendula extract is a classic botanical known for its gentle, soothing character, which is particularly welcome around the delicate eye contour. Retinol is a well-known cosmetic active associated over time with smoother-looking skin and a more refined texture. It's important to note that in a rinse-off patch format, the contact time is limited, so effects are primarily superficial and temporary, focused on hydration, comfort, and an immediate freshened look.
