LuLuLun Hydra AZ Mask is a Japanese daily-use sheet mask featuring azelaic acid derivative as its key ingredient. This facial mask targets skin concerns like excess sebum, enlarged pores, and skin roughness while providing hydration. The mask uses a specially developed "melty feel" sheet that adheres closely to the skin, creating a water-layer sensation. Best suited for those with oily, troubled skin or those concerned with pore visibility. The formula includes niacinamide, mild AHA, and next-generation hyaluronic acid for comprehensive skincare benefits.
