Thank you for viewing. This is a circular, needle-shaped sheet based on micro-patches and containing niacinamide, etc. It prevents skin irritation and refines the skin's texture. The cause of acne is "acne bacteria." Acne bacteria tend to live on dry skin and oily, shiny skin, and it is widely known that acne occurs when these acne bacteria proliferate. This product contains niacinamide, an ingredient that suppresses the growth of acne bacteria, the cause of acne, and is a cosmetic product that helps to eliminate acne. Although it is new and unused, please refrain from purchasing if you are nervous about home storage (^人^)
