A premium anti-aging hydrogel mask that pairs encapsulated retinal liposomes with lotus flower extract for a potent yet gentle resurfacing and brightening treatment. K-SECRET's Seoul 1988 Hydrogel Mask uses liposomal delivery technology to encapsulate retinal — the most potent non-prescription vitamin A derivative — ensuring controlled, stable release into the skin for maximum efficacy with minimal irritation, while lotus flower extract delivers whitening, antioxidant, and soothing benefits within a deep-contact hydrogel sheet.

Key Benefits

• Retinal Liposome Technology — Liposomal encapsulation protects retinal from oxidative degradation and delivers it in a time-released, skin-compatible form that maximizes penetration and efficacy while significantly reducing the irritation risk associated with conventional retinoid treatments.
• Retinal Anti-Aging & Resurfacing — Retinal (retinaldehyde) is one conversion step from retinoic acid, making it significantly more potent and faster-acting than retinol. It visibly reduces fine lines, wrinkles, and skin laxity while accelerating cell turnover for smoother, firmer skin.
• Lotus Flower Brightening — Rich in antioxidants, flavonoids, and natural brightening compounds, lotus flower extract fades hyperpigmentation, evens skin tone, and imparts a luminous, porcelain-like radiance that complements retinal's resurfacing action.
• Hydrogel Deep Contact — Hydrogel sheet format adheres closely to every contour of the face, creating an occlusive seal that prevents essence evaporation and maximizes the absorption of retinal and brightening actives deep into the skin.
• Soothing & Comfortable — Lotus flower's natural anti-inflammatory and calming properties reduce post-retinal redness and sensitivity, making this mask more tolerable for retinoid-new skin than standard retinal treatments.

How to Use

After cleansing and toner, apply the hydrogel mask to the face and leave on for 20–30 minutes. Remove and gently pat remaining essence into the skin. Do not rinse. Follow with moisturizer. Use 1–2 times per week in the evening. Always apply SPF the following morning. Introduce gradually if new to retinoids — begin with once per week and increase as tolerated.
