The product is hygienically packaged in a zipper-sealed pouch, so there's no need to worry. It's compact in size, making it easy to carry when traveling or going out. When opened, there are two patches inside, made of a slightly tacky yet elastic material that adheres well to the skin. After cleansing, I left the patches on for about 20 minutes, and they dried quite a bit when I removed them. I just used a toner to finish, and the high-purity glutathione seemed to be well-absorbed into my skin. Looking at the photos, there's a subtle, inner glow rather than an oily shine, and gently pressing the area feels pleasantly bouncy. UV damage to the skin is prevented, and melanin production that leads to dark spots and freckles is blocked in all three stages. Consistent use should yield faster results. Plus, it contains moisturizing and wrinkle-improving ingredients like adenosine and hyaluronic acid, with minimal irritation.

The effects were quite good, but the price is a bit burdensome for me.
